Free Git-based CMS setup using Decap CMS, standalone GitHub data repo and Netlify-based GitHub auth

Last updated on 27 Jan. 2026
This post branced off from my recent post: Building Test Static School Website: Next.js static export vs Plain React, Using ThemeWagon Si-Education Next.js Template - Part 2.

Quick Info

GitHub public standalone data repo: https://github.com/ravisiyer/testschoolws-data

GitHub Pages deployment of above data repo: https://ravisiyer.github.io/testschoolws-data. JSON data URL in it (live app data): https://ravisiyer.github.io/testschoolws-data/data/data.json

Decap CMS UI URL on Netlify: https://eloquent-sunburst-0d336b.netlify.app/admin [Requires GitHub login with write access to the data repository.]
========================================================

Summary

1) Architecture / Design Overview

This is a free (zero-cost) Git-backed CMS and hosting setup using Decap CMS, a standalone public GitHub data repository, and Netlify-based GitHub authentication.

At a high level, the system has three clearly separated responsibilities:

A. GitHub (Source of Truth)

  • A public GitHub repository contains data/data.json.

  • This repository is the single source of truth for site content.

  • GitHub Pages is enabled on this repo, so the latest data.json is always available at a public URL.

  • Any frontend (Next.js, static site, etc.) can fetch this JSON at runtime.

B. Decap CMS (Content Editing UI)

  • Decap CMS runs entirely as a static admin UI (/admin) hosted on a Netlify site.

  • Editors authenticate using GitHub OAuth.

  • Decap CMS edits data.json and commits changes directly to the GitHub repository via Netlify Identity + Git Gateway.

  • No server, database, or custom backend is required.

C. Netlify (Minimal, Supporting Role)

Netlify is used only for:

  • Hosting the static Decap CMS admin UI

  • Providing GitHub OAuth authentication

  • Acting as a Git Gateway between Decap CMS and GitHub

The Netlify site is not the production site and not the canonical data source.
Even if Netlify builds are stopped, the system continues to work as long as authentication is available.

Data Flow (End-to-End):

  1. Editor logs into /admin of Netlify site using GitHub OAuth.

  2. Decap CMS reads the current content state from GitHub.

  3. Editor edits content and clicks Publish.

  4. Decap CMS commits changes to GitHub.

  5. GitHub Pages automatically redeploys site resulting in updated data.json.

  6. The frontend site fetches the updated JSON from GitHub Pages.

This achieves a Git-native CMS with:

  • No database

  • No custom backend

  • No paid hosting

  • A clean failure mode (GitHub remains usable even if CMS breaks)

2) Key Instructions / Operational Notes

Repository Structure

  • The GitHub repository must be public (for GitHub Pages access).

  • GitHub Pages should be enabled on the main branch.

Decap CMS Setup

  • Use a minimal admin/index.html.

  • Do not manually call Decap.init() — Decap auto-initializes.

  • Use git-gateway as the backend.

  • Use GitHub OAuth only; email/password login is unnecessary.

Netlify Usage

  • Netlify is required only for:

    • Identity (OAuth)

    • Git Gateway

    • Hosting /admin

  • Continuous deployment can be:

    • Enabled during setup and testing

    • Disabled later to minimize free-tier usage

  • Even if Netlify deployment is stopped:

    • CMS edits still update GitHub

    • GitHub Pages continues to serve updated data

    • Netlify site will have old data but that should be ignored

Frontend Integration

  • The frontend can fetch data.json at build-time or runtime from GitHub Pages.

  • The frontend does not need to know about Netlify or Decap CMS.

  • This keeps the production site fully independent of the CMS tooling.

Operational Discipline

  • Always git pull before making local changes.

  • If Decap CMS creates commits:

    • Pull them locally

    • Resolve merges immediately

    • Push without delay

  • Use Git tags (e.g., cms-stable-baseline created on 25 Jan. 2026) to mark known-good CMS states.

Final Outcome

This setup provides a low-cost, Git-native, editor-friendly CMS that:

  • Respects Git as the source of truth

  • Avoids vendor lock-in

  • Keeps production hosting independent and free

  • Degrades gracefully if CMS tooling ever fails

It is not a “polished enterprise CMS,” but it is a robust, transparent, and maintainable solution for small sites and cost-sensitive deployments.

Related CG chat: Pages CMS vs Decap CMS

Me: Is Pages CMS an alternative for Decap CMS

CG: Yes — Pages CMS can serve as an alternative to Decap CMS (formerly Netlify CMS) for managing content on static sites, depending on your needs. Both are open-source, Git-based content management systems intended to give non-technical editors a UI for updating content that lives in your Git repository, but they have different design focuses and maturity levels.(pagescms.org)

Core Comparison

Pages CMS

  • A lightweight, GitHub-centric CMS designed specifically to simplify content editing for static site generators like Next.js, Hugo, Astro, Jekyll, 11ty, etc.(pagescms.org)

  • Features include visual editing, rich text support, media management, search, and configuration via a single YAML file.(pagescms.org)

  • It aims for simplicity and an intuitive editing experience with minimal setup.(pagescms.org)

  • Typically accessed via a hosted web UI that commits changes back to the repository.(CMS Conf)

Decap CMS

  • The rebranded successor to Netlify CMS, maintained as an open-source project with a broader user base and community support.(decapcms.org)

  • Also Git-based, but tends to be more feature-rich and mature, with deeper extensibility and customization options (e.g., custom widgets, preview pipelines, Git Gateway for non-GitHub workflows).(decapcms.org)

  • Works with many static site generators and has more ecosystem discussion and tooling already in place.(decapcms.org)

When Pages CMS Is a Good Alternative

You would consider Pages CMS as an alternative to Decap CMS if:

  1. Ease of Setup and Use Is a Priority — Pages CMS is designed to reduce configuration complexity and provide a friendly editing UI out of the box.(pagescms.org)

  2. You’re Using GitHub and Static Site Generators — It directly integrates with GitHub and supports most flat-file workflows.(Jamstack.org)

  3. Your Site Is Small to Medium — For blogs, documentation, and marketing sites where heavy content workflows aren’t needed, Pages CMS can be simpler.(CMS Conf)

When Decap CMS Might Be Preferable

Decap CMS may still be the better choice if:

  1. You Need Advanced Customization — Decap has a more established plugin/widget ecosystem and richer editor capabilities.(decapcms.org)

  2. Your Team Isn’t GitHub-Only — With Git Gateway, Decap can support editors without GitHub accounts.(decapcms.org)

  3. Community and Longevity Matter — Being a more widely adopted project means more examples, community help, and long-term viability.(AlternativeTo)

Other Alternatives Worth Considering

Aside from Pages CMS and Decap CMS, there are other Git-based CMS options for static sites, such as:

  • Nuxt Studio — editing interface for Nuxt Content sites.(AlternativeTo)

  • TinaCMS — inline visual editing with React support.(libhunt.com)

  • Sveltia CMS — a modern replacement for Decap CMS with improved UX and i18n support.(npmjs.com)

  • Static CMS — another Git-based editing UI (though less actively maintained).(AlternativeTo)

Summary

Feature / AspectPages CMSDecap CMS
Git-basedYesYes
Ease of SetupHigherModerate
Editing UIVisual & simpleRich & customizable
Maturity & ecosystemEmergingMore mature
Supports non-GitHub workflowsLimitedYes (via Git Gateway)

Conclusion: Yes — Pages CMS can be an alternative to Decap CMS if your project needs simplicity, GitHub-first workflows, and a lightweight editing experience. For more complex workflows, deeper customization, or broader ecosystem support, Decap CMS may still be the stronger choice.(pagescms.org)

Me: I am experimenting with a Next.js template si-education that is static site landing page for an education site. It uses a data.json file to drive some of the elements shown in the landing page. I would like to have a web UI that enables editing this data.json, committing to GitHub which triggers a build. For deployment I am using GitHub Pages. There is an additional complexity but let me add that later. If Decap CMS has more features and is better established in the community, I prefer using that. I looked at its website. Its documentation is heavily tied to Netlify. That put me off a little. But if it works well with GitHub Pages too then I think I should use Decap CMS. Your comments please

[CG was helpful with the config.yml file creation. But on admin/index.html CG went off track and there were lot of issues. I did look at Decap CMS docs but in my quick browse, I could not locate an example suitable for my use case. The examples seemed to be more on the lines of single repo having website as well as data which probably was used  by Static Site Generators in build process. The config.yml creation by CG perhaps led me to rely on CG for the index.html too. In hindsight, this was a mistake. Eventually, the issues we got into, got resolved with me looking at Decap docs and having a top level browse of Decap CMS GitHub repo code which included some examples (they were hard to locate or else I may have latched onto it earlier). ... In the sections below, I have given only some of the messages to focus on what is useful.]

Me: Great! Now one complexity is that my Next.js project is a private GitHub repo for which in my free tier account, GitHub Pages deployment is not allowed. So I have deployed the site to another public GitHub repo, using gh-pages package to do the deployment from source private GitHub repo to public deployment GitHub repo and GitHub Pages site. Did you understand this setup?

...
Me: The data lives in a data.json file which is kept in public/data directory and so gets published to out folder and to deployed site.

In a previous chat on this project, we considered having a separate public repo that holds only the data.json file , with the static site frontend fetching (not reading) the data from it. This separate data public repo could have Decap CMS set up with it.

Is this a workable and good approach?
...

[I shared data.json content]

Me: About: Make any small naming cleanups you want in data.json
As of now, I am simply experimenting and learning. An advantage of going with same names now is that I don't have to change the next.js app code that references these JSON properties. So let us skip that for now.

Please guide me in creation of a public data repo for this data.json with Decap CMS support.
...

[CG provided config.yml suitable for data.json - that was a big help. It also provided admin/index.html but, IFIRC, did not know that GitHub requires a server for authentication with Netlify being one solution for that.]

Me: Great. I will follow this but with slight changes:
1) In VSCode (on my Win 11 PC), I will create a new project and set up the files in it as you have described above. I will also create a git repo.
2) After the files are setup, I will create a public repo for it in GitHub and then connect my VSCode project to the GitHub public repo.
3) Then I will follow remaining steps like GitHub authentication setup.
Will that be OK?
...

Me: Followed instructions. On going to admin page, I am shown GitHub Login option. On clicking it, I get a window with Not found message. URL is: https://api.netlify.com/auth?provider=github&site_id=ravisiyer.github.io&scope=repo

BTW my admin page URL is: https://ravisiyer.github.io/testschoolws-data/admin/  
The repo is named testschoolws-data
...
[The associated GitHub public repo: https://github.com/ravisiyer/testschoolws-data . The initial commit was made in early hours of 25 Jan. 2026. As of 16:40 on 26 Jan. 2026, the repo has 15 commits which capture the various trials made and eventual success, followed by a tagged stable version - cms-stable-baseline.]

Me: I will do that. But before that, here are the top lines of my config.yml:
backend:
  name: github
  repo: ravisiyer/testschoolws-data
  branch: main
  auth_scope: repo
  site_url: https://ravisiyer.github.io/testschoolws-data/
...

Me: Earlier on, you had asked me to create admin/index.html not admin/auth/index.html. So I have only admin/index.html
...

Me: I confirmed that https://ravisiyer.github.io/testschoolws-data/admin/auth/
shows blank Authenticating screen 
But for https://ravisiyer.github.io/testschoolws-data/admin/#/
Once again, it shows Not found with URL as: https://api.netlify.com/auth?provider=github&site_id=ravisiyer.github.io&scope=repo
...

Me: https://decapcms.org/docs/github-backend/
says: Because GitHub requires a server for authentication, Netlify facilitates basic GitHub authentication.
-----
That implies there must be some way to use Netlify only for this GitHub authentication but still have the CMS on GitHub. Can you search the web to check it out?
...

Recommendation for your setup

Since you want:

  • GitHub Pages for site

  • Decap CMS for editing

  • No full Netlify deployment

Then you have two practical choices:

Option A: Use Netlify only as an authentication proxy

  • Deploy a minimal site on Netlify

  • Enable Identity + Git Gateway

  • This handles GitHub OAuth for Decap CMS

  • Your GitHub Pages site still fetches data from the public repo

  • CMS will work without full Netlify deployment of the main site

This is the easiest school project path because you use Netlify exactly as Decap expects.

Option B: Deploy your own OAuth proxy service

  • Use an existing Decap-OAuth proxy implementation (e.g., Cloudflare Worker)

  • Configure Decap CMS to use that proxy as the backend.base_url

  • No Netlify needed

  • Longer setup, but clean architecture

This is the purely static + own serverless auth path.

Conclusion

Yes, there is a way to use Netlify only for GitHub authentication with Decap CMS, while hosting everything else (CMS UI + site) on GitHub Pages. This is explicitly supported by the Decap documentation because it calls out Netlify as the provider that “facilitates basic GitHub authentication.”

Alternatively, you can avoid Netlify entirely by running your own OAuth proxy — but that requires additional infrastructure.

If you want, I can provide step-by-step instructions for either Option A (Netlify for auth only) or Option B (self-hosted proxy) tailored to your exact repo and domain. Just tell me which path you want.

Me: If I use Option A, I will be using Netlify in a minimal way and so possibility of encountering free tier limits is low. am I right?

CG: Yes — your understanding is correct.

If you use Option A (Netlify only for authentication: Identity + Git Gateway), the likelihood of hitting Netlify free-tier limits is very low, especially for an experimental or low-traffic setup like yours.

Let me explain this precisely, without hand-waving.

What Netlify is actually doing in Option A

In your architecture:

  • GitHub Pages

    • Hosts your static site

    • Hosts the Decap CMS admin UI (/admin)

  • GitHub

    • Stores data.json

    • Receives commits from Decap CMS

    • Triggers your existing GitHub Pages build/deploy flow

  • Netlify

    • Does only one job:

      • Acts as a server-side OAuth broker between Decap CMS and GitHub

      • Issues short-lived access tokens via Git Gateway

Netlify is not:

  • Hosting your production site

  • Serving your static pages to end users

  • Running builds for your site

  • Serving your assets or JSON to visitors

That dramatically reduces usage.

Netlify free tier limits — what matters here

The Netlify Free plan limits that are relevant to Option A are essentially:

1. Identity (authentication)

  • Intended for small to medium projects

  • Limits are based on active users, not logins per se

  • For a single editor (you):

    • You are nowhere near any practical limit

2. Git Gateway usage

  • Git Gateway is a thin proxy

  • It only runs when:

    • You log into /admin

    • You save or publish content

  • Each save is a single Git commit

Even with daily experimentation, usage is trivial.

3. Bandwidth & build minutes

  • Irrelevant in your case

  • You are not deploying your site on Netlify

  • You are not using Netlify builds

  • Public users never hit Netlify at all

This is the key point many people miss.

What could realistically hit limits?

Only two scenarios, neither of which applies to you right now:

  1. Many CMS editors

    • Dozens or hundreds of authenticated users

    • Not your use case

  2. High-frequency automated CMS writes

    • Programmatic edits or bots committing repeatedly

    • Not how Decap CMS is designed to be used

For a single developer / site owner, Netlify’s free tier is effectively “unlimited” for this role.

Architectural judgement (important)

From a system design perspective, Option A is actually quite clean:

  • GitHub Pages stays purely static

  • OAuth complexity is delegated to a service designed for it

  • You avoid maintaining your own auth proxy

  • You do not tie your site hosting to Netlify

This is why Decap CMS documentation still leans on Netlify: not because it forces Netlify hosting, but because OAuth is genuinely painful to self-host correctly.

Bottom line

Your statement:

“If I use Option A, I will be using Netlify in a minimal way and so possibility of encountering free tier limits is low.”

is accurate.

More strongly stated:

  • For your current learning + experimentation phase,

  • With a single editor,

  • Using Netlify only for Decap CMS authentication,

You are extremely unlikely to encounter any Netlify free-tier limits.

Proceeding with Option A is a sensible, low-risk, low-maintenance choice.

If you want, next I can:

  • Lay out the exact minimal Netlify setup (no unnecessary features), or

  • Help you cleanly document this architecture for your own reference, or

  • Explain when it would make sense to move to Option B later.

Me: Well, even though I am currently experimenting and learning, I am trying to create a pathway to a production build for any customer that has zero hosting cost.
But from what you said, I could still achieve this with netlify by asking customer to create a Netlify account and have very limited users as editors for the data. Then that customer Netlify account will stay within free tier limits for normal production site data updates work. And if the customer crosses that limit due to heavy data updates and lots of editors then he has the pathway of using paid Netlify account with higher limits. Please validate my view.

CG: Your view is sound, internally consistent, and production-viable. I will validate it precisely and also point out the one boundary you should explicitly acknowledge when presenting this pathway to a customer.

Validation of your proposed production pathway

You are proposing:

Zero hosting cost for the public website
Minimal, optional cost only if CMS usage grows
Clear upgrade path without architectural change

That is exactly what your current design achieves.

Let’s restate your production architecture clearly:

Production architecture (validated)

Public site

  • Hosted on GitHub Pages

  • Cost: ₹0 / $0

  • Scales well for static content

  • Independent of CMS provider

Content storage

  • GitHub repository (public or private, your choice)

  • Cost: ₹0 / $0

CMS UI

  • Decap CMS hosted on GitHub Pages (same repo)

  • Cost: ₹0 / $0

Authentication & write access

  • Netlify (Identity + Git Gateway)

  • Customer creates their own Netlify account

  • Editors are limited in number

  • Cost: ₹0 / $0 initially

This is a clean separation of concerns, which is exactly what you want for a reusable customer solution.

Why this stays within Netlify free tier in real life

Your reasoning here is correct.

For a typical small education site / school / institute:

  • Editors: 1–3 people

  • Edit frequency:

    • Courses updated occasionally

    • Testimonials added rarely

    • Navigation changes very rarely

  • CMS usage:

    • A few logins per week or month

    • A handful of Git commits per edit session

This usage profile is far below Netlify’s free-tier stress points.

Netlify is not charging for:

  • The number of Git commits

  • The size of JSON files

  • The number of public site visitors (because visitors don’t hit Netlify at all)

Upgrade path is clean and non-breaking

This is an important strength of your approach.

If a customer later:

  • Adds many editors, or

  • Wants frequent content churn, or

  • Starts using CMS as an operational tool rather than a simple editor

Then:

  • They do not need to change architecture

  • They do not need to migrate data

  • They simply:

    • Upgrade Netlify plan

    • Increase Identity / Git Gateway limits

That is a commercially reasonable escalation, not vendor lock-in.

One important clarification you should state explicitly to customers

To be precise and honest, you should phrase your offering like this:

“The public website has zero hosting cost.
The content editing system also runs at zero cost for normal usage.
Only if you add many editors or perform very frequent updates would a paid Netlify plan be required.”

This avoids the trap of promising absolute zero cost forever, which no professional system should promise.

You are offering:

  • Zero cost for normal operation

  • Predictable, optional cost for growth

That is a responsible engineering claim.

Strategic assessment (strong opinion)

What you are designing is actually better than many small CMS setups because:

  • You avoid server hosting entirely

  • You avoid database maintenance

  • You keep content versioned in Git (audit trail)

  • You give customers ownership of:

    • GitHub account

    • Netlify account

    • Their data

This aligns well with:

  • Small schools

  • NGOs

  • Trusts

  • Individual educators

Exactly the audience suggested by the si-education template.

Bottom line

Your understanding is correct and well thought through.

Yes:

  • You can reach production with zero hosting cost

  • Yes:

    • Netlify can be used minimally and safely

    • Free tier is sufficient for normal editorial usage

  • Yes:

    • There is a clean, non-disruptive upgrade path

This is a defensible architecture, both technically and commercially.

If you want, next we can:

  • Turn this into a 1-page architecture note you can reuse for clients, or

  • Define editor role limits and best practices to keep customers in free tier, or

  • Compare this approach against Headless CMS SaaS offerings to articulate why yours is leaner.

Me: OK. Now please guide me to implement Option A. I already have a netlify account.
...
[CG provided detailed instructions.]

Me: Netlify Identity is now deprecated but will continue to work. We recommend new projects use the Auth0 extension or integrate their own auth solution.
...

Me: Is Auth0 extension free to use and will that work for our case.

CG: Here’s a clear and realistic answer to your question about using the Netlify Auth0 extension with Decap CMS — specifically with Option A, where the site itself is hosted on GitHub Pages, and Netlify is used only for authentication:

1. Is the Auth0 extension free to use?

The Auth0 extension itself is available in the Netlify Extensions Directory and can be installed on your Netlify site. However:

Auth0 Pricing

  • Auth0 offers a free tier that you can use to create an Auth0 tenant and applications without cost.

  • The free tier normally includes a quota of monthly active users (MAUs). According to Auth0 pricing, the free plan supports up to 25,000 monthly active users before requiring a paid plan.(Auth0)

That means:

  • For a typical small‑site editing use case (e.g., a handful of content editors), the Auth0 free tier is more than sufficient.

  • Auth0’s free tier lets you use OAuth, user authentication, and basic user management without cost.(Auth0)

Conclusion: Yes — you can use Auth0 on the free plan in most small scenarios.

2. Will the Auth0 extension work for your case with Decap CMS?

Here are the key constraints and realities:

Netlify Identity vs Auth0

  • Netlify Identity + Git Gateway historically served as the authentication and token broker for Decap CMS with GitHub backend.

  • But Netlify Identity is now deprecated and may not be available on newer Netlify sites.(Netlify Docs)

Auth0 Extension Availability

Netlify has an official Auth0 extension that integrates Auth0 with Netlify sites. You can install it from:

This extension allows you to:

  • Connect your Netlify site to an Auth0 tenant

  • Manage user authentication and session tokens from Auth0

  • Leverage Auth0 for secure login

However, there’s a key limitation documented in the Netlify forums:

RBAC / JWT Management and Netlify

  • Netlify’s support thread indicates that using role‑based access control (RBAC) or customizable JWT authentication with external providers like Auth0 on a static site is only supported on Netlify’s Enterprise plan.(Netlify Support Forums)

In plain terms:

  • You can integrate Auth0 for authentication using the Netlify Auth0 extension on the free or Pro plans.

  • But Netlify’s static RBAC integration with Auth0 tokens (for securing a static admin interface) may require a higher plan.

This does not mean Auth0 won’t work at all — it means that the integration path Netlify currently supports for static admin protection and token exchange might not be available on the free tier without custom functions or workarounds.

3. What this means for your Decap CMS + Auth0 plan

Option A: Use Auth0 via Netlify extension

  • You can install the Auth0 extension on your Netlify site.

  • Your Auth0 tenant can authenticate users (e.g., school admins) with no cost under the free tier.

  • But the Netlify‑provided integration may not natively extend to Decap CMS token exchange without additional work, due to RBAC and JWT handling limitations on free/pro plans.

You would likely need to:

  1. Configure the Auth0 extension

  2. Manually generate GitHub tokens from Auth0 login

  3. Adapt the Decap CMS config to use that auth flow

This is possible, but not as turnkey as it once was with Netlify Identity + Git Gateway.

4. A more practical recommendation for your case

Given the current state of:

  • Netlify Identity being deprecated,

  • Netlify Git Gateway being deprecated, and

  • Auth0 requiring additional integration work on non‑Enterprise plans,

the most practical and free path for Decap CMS authentication is:

Option B: Use a Standalone OAuth Proxy (e.g., decap‑proxy)

There are community tools (such as decap-proxy) that allow you to:

  • Create a GitHub OAuth App

  • Deploy a lightweight proxy (e.g., on Cloudflare Workers or Vercel)

  • Use that proxy to authenticate with GitHub for Decap CMS

  • Avoid Netlify entirely

This approach:

  • Does not cost anything (Cloudflare Workers has a generous free tier)

  • Works independently of Netlify or GitHub Pages

  • Does not require an enterprise plan

If you want a zero cost, production‑ready authentication solution for Decap CMS on GitHub Pages, this is currently the most straightforward long‑term path.

I can provide step‑by‑step instructions on how to set up such a proxy and configure Decap CMS to use it if you want.

Summary

Auth0 Extension:

  • Auth0 free tier is generous and workable for small editorial use.(Auth0)

  • The Netlify Auth0 extension integrates Auth0 with Netlify sites.(Netlify Docs)

  • However, using Auth0 for Decap CMS login via Netlify may be constrained on non‑Enterprise plans.(Netlify Support Forums)

Decap CMS and authentication today:

  • Netlify Identity and Git Gateway worked previously, but are deprecated.(Netlify Docs)

  • Auth0 integration via Netlify may work for Auth0 login, but not necessarily for Decap CMS GitHub auth without custom steps.

Best practical path for zero cost hosting + Decap CMS + GitHub Pages:

  • Consider a custom OAuth proxy (e.g., decap‑proxy) for direct GitHub OAuth without Netlify.

If you’d like, I can now give you a step‑by‑step guide to set up decap‑proxy (or a similar OAuth proxy) and configure your Decap CMS to use it. This is likely the cleanest long‑term solution for your production pathway.

Me: For now, I will try Netlify Identity . Later I will explore custom OAuth proxy (e.g., decap‑proxy) for direct GitHub OAuth without Netlify. How's that?

[Later, IFIRC, as I was struggling to get Netlify Identity working, I did have a quick look at and quick attempt to install decap-proxy. [IFIRC, https://github.com/sterlingwes/decap-proxy : "A Cloudflare Worker Github OAuth proxy for Decap CMS. Allows redirecting to the authorization flow and calling back to Decap."] But I am new to Cloudflare. I tried it but this worker stuff was too strange for me to fix the build or whatever it is called failure I was getting. There was also some wrangler stuff to be done as per Readme instructions, and I have no idea about wrangler. So I gave up this attempt. In future, if necessary, I can try it out again but with willingness to invest time to learn about Cloudflare workers and wrangler. I did not use ChatGPT for this attempt.

https://stackoverflow.com/questions/79009410/can-i-use-decap-cms-on-github-pages-without-hosting-the-site-on-netlify : While it is true you need to setup your own OAuth Proxy when using github pages as a backend, you can setup a free cloud flare worker to do it for you and it is pretty simple github.com/sterlingwes/decap-proxy]

CG: ...

✅ Summary

  • Short-term: Use Netlify Identity → fast, simple, works, free.

  • Long-term: Migrate to a custom OAuth proxy → fully independent, zero cost, production ready.

This plan gives you the best of both worlds: immediate results now, and a clean upgrade path later.

If you want, I can now give you a step-by-step “minimal Netlify Identity setup” checklist for your testschoolws-data repo so you can quickly get Decap CMS login working.

Do you want me to do that next?

Me: Yes to last point

[CG gave detailed instructions.]

Me: I have admin/auth/index.html. Should I retain it?
In config.yml, I have auth_endpoint: auth
Should I retain it?
...

Me: I will retain admin/auth/index.html for now till I get site working. Then I will delete it.
First few lines of config.yml:

...

Me: Decap shows me a login screen with email id and password. I presume I need to provide my Netlify credentials here. Am i right?
...

Me: I get a 't' on login screen at login attempt with Netlify credentials. I get that even with wrong credentials. BTW I did not set a password for my email id (which is my Netlify email id) that I invited. Am I missing something here

CG: ...

About the mysterious “t”

You asked implicitly about it, so here’s the truth:

  • The t is a truncated JavaScript error output

  • It usually means:

    • Token request failed

    • Identity returned an unexpected response

  • It is not actionable by itself

  • Fixing Identity activation fixes it

Bottom line (very clear)

  • ❌ You cannot log in without setting a Netlify Identity password

  • ✅ The password is set only via the invite email

  • ❌ GitHub credentials are irrelevant here

  • ✅ Once the invite is accepted properly, Decap CMS login will work

...

Me: ON clicking invite in email response earlier, I was shown some error message. I tried it again now. It takes me to URL: https://eloquent-sunburst-0d336b.netlify.app/#invite_token=--snipped--

And the screen message shows: Page not found
Looks like you’ve followed a broken link or entered a URL that doesn’t exist on this site.

If this is your site, and you weren’t expecting a 404 for this path, please visit Netlify’s “page not found” support guide for troubleshooting tips.
...

Me: It only has send reset password email.
...

Me: IN Registration preferences, there is an External Providers option which was not set. I can set it to GitHub. Shall I do that and try again?
...

Me: It does not show GitHub login option
...

Me: ON logging in at https://eloquent-sunburst-0d336b.netlify.app/admin/#/
with netlify credentials, it says:
t: invalid_grant: Email not confirmed
...

Me: It doesn't work. I think this Netlify auth with Github hosting is too complicated. Teh big issue is that there is no official documentation clearly describing it.
Meanwhile what I noticed is that Netlify pulled in all the files of the GitHub project. So https://eloquent-sunburst-0d336b.netlify.app/data/data.json is showing the data!

As I have spent so much time on this, I will try out modifying config.yml to use Netlify deployed site instead of GitHub and see whether that works. What do u say?
...

Me: Before I close this session let me share a few points. Please validate them.
1) Decap-CMS is sort-of native to Netlify. While its docs do say GitHub is supported, the main documentation support is for netlify. So if I use Decap-CMS for a solution, it should be only with Netlify. I mean, it is not really a strongly supported system. It is more of a poor man's CMS with poor man level support - that's the impression I am getting.

2) For GitHub usage as CMS, it is better to use Pages CMS, https://pagescms.org/ as that seems to be native to GitHub (and limited to GitHub). So documentation and developer support for GitHub may be decent. It also is a poor man's CMS but it is poor man's CMS for GitHub and not netlify.

What do u say?

CG: Your assessment is largely correct, and I will validate it point-by-point, with some important nuance so you end up with an accurate mental model rather than a frustrated one.

I will be frank and technical.

1) “Decap CMS is sort-of native to Netlify”

Verdict: Essentially correct

Decap CMS is formally “Git-based and provider-agnostic”, but in practice:

  • Netlify is the reference platform

  • Netlify Identity + Git Gateway is the only first-class, fully documented auth path

  • All other backends (GitHub direct, GitLab, Bitbucket) are:

    • Less documented

    • More brittle

    • Heavily dependent on OAuth proxies or third-party services

So while GitHub is supported, it is not equally supported.

Your lived experience confirms this.

Why this is the case (important context)

Decap CMS is the continuation of Netlify CMS after Netlify stepped back. However:

  • The original architecture assumed Netlify

  • The authentication model assumes a server

  • GitHub Pages is serverless static only

So the “GitHub Pages + Decap” story is:

  • Technically possible

  • Architecturally awkward

  • Poorly documented

  • Poorly tested

This is not accidental; it is historical debt.

Your phrase “poor man’s CMS” — is it fair?

Yes, with precision:

  • It is a lightweight, Git-first CMS

  • It is excellent for:

    • Small teams

    • Low editorial complexity

    • Developer-controlled content

  • It is not a general-purpose CMS

  • Support is community-driven and uneven

So your intuition is accurate, though I would phrase it as:

“Decap CMS is a lightweight Git-CMS whose only truly polished integration is Netlify.”

2) “For GitHub usage as CMS, Pages CMS seems better”

Verdict: Yes — for GitHub-only workflows, Pages CMS is the better fit

Pages CMS is conceptually honest in a way Decap CMS is not:

  • It is explicitly GitHub-native

  • It does not pretend to be provider-agnostic

  • Authentication is GitHub OAuth

  • Hosting is GitHub Pages

  • Permissions map directly to GitHub repo access

That alignment matters a lot.

Why Pages CMS feels “cleaner”

Because:

  • No Identity layer

  • No Git Gateway

  • No OAuth proxy hop

  • No server illusion

Everything is:

Browser → GitHub OAuth → GitHub API → GitHub repo

That simplicity translates into:

  • Better predictability

  • Fewer edge cases

  • Less undocumented behavior

Is it still a “poor man’s CMS”?

Yes — but as you said:

“It is a poor man's CMS for GitHub”

That is exactly right.

And that is not a criticism — it is proper positioning.

The deeper truth (this is the key insight)

What you are really discovering is this:

Git-based CMSes are not interchangeable abstractions.
They inherit the strengths and weaknesses of their host platform.

  • Decap CMS inherits Netlify’s strengths and assumptions

  • Pages CMS inherits GitHub’s strengths and constraints

Trying to force one into the other’s territory creates friction — which you felt.

Practical guidance going forward (important)

Based on everything you have done and learned:

If your solution is:

  • GitHub Pages

  • Zero hosting cost

  • Few editors

  • Simple JSON / Markdown data

👉 Pages CMS is the more honest and maintainable choice

If your solution is:

  • Netlify hosting (even minimally)

  • Decap CMS UI

  • Non-technical editors

  • More structured collections

👉 Decap CMS + Netlify is the correct pairing

Trying to mix:

  • Decap CMS

  • GitHub Pages

  • No Netlify hosting

…is the hard mode, and not worth it unless you are building tooling, not a product.

Final validation of your two points

1️⃣ Correct in substance
Decap CMS is effectively Netlify-centric despite nominal GitHub support.

2️⃣ Correct and well reasoned
Pages CMS is the better GitHub-native CMS and aligns with GitHub Pages much more cleanly.

Your conclusions are not emotional reactions — they are architecturally sound.

One last reassurance before you close

You did not waste time.

You now understand:

  • The real limits of Git-based CMSes

  • The tradeoffs between Netlify and GitHub

  • Which tool matches which hosting philosophy

That insight will save you and your customers real pain later.

...

Me: I am now trying out Netlify site with config.yml modified to use netlify site instead of GitHub. I am facing same issue of login user not being confirmed. Email reset leads to Page not found error. ...
https://decapcms.org/docs/choosing-a-backend/ talks of some Netlify Identity Widget. Can you check that? Do we need to use that?
...

Me: I know about Netlify having deprecated Identity and related stuff. ... But as I invested quite a few hours exploring Decap CMS, I want to invest some more time to see if it works even with depracated Identity and related stuff. Are you with me on this?
...

Me: to get that working, let us try using Netlify Identity widget as that is what Decap docs instruct. Do you agree?
...

[CG provided some code, which now we know was more complicated than needed.]

Me: The decap docs page has this:
When a user logs in with the Netlify Identity widget, an access token directs to the site homepage. In order to complete the login and get back to the CMS, redirect the user back to the /admin/ path. To do this, add the following script before the closing body tag of your site’s main index page:

<script>
  if (window.netlifyIdentity) {
    window.netlifyIdentity.on("init", (user) => {
      if (!user) {
        window.netlifyIdentity.on("login", () => {
          document.location.href = "/admin/";
        });
      }
    });
  }
</script>
------
The code you provided does not have the above.
...

CG ...

✅ Key point

  • The Decap docs redirect snippet is optional for /admin/ itself

  • It is required only if you want login from the main site to redirect properly to the CMS

  • For your testing, you can first focus on admin/index.html login, then add the redirect later if needed

...
Me: Let me try out the code you had provided earlier (admin/index.html) As of now, we don't have a /index.html
...

Me: Going to admin gives a blank screen. Browser console has this error message:
Uncaught TypeError: Cannot read properties of undefined (reading 'on')
    at admin/:19:16
----------------

I am frustrated now. If u can give an easy solution, fine I will try it. If not, let me see if there is some other clear guide on using Decap CMS with Netlify today.
...

Me: https://identity.netlify.com/v1/netlify-identity-widget.js returns the script right away. Can you retrieve it and see if the code you provided matches what https://identity.netlify.com/v1/netlify-identity-widget.js has?
...

Me: Let us add simple debugging JS code that tells us whether netlifyIdentity got loaded or not.
...

Me: What the screen shows now:
Debug Netlify Identity
✅ Netlify Identity Widget loaded successfully!
✅ Identity initialized successfully!
❌ Error during identity init: TypeError: Cannot read properties of undefined (reading 'on')
...

Me: Great that we found the bug in your code. Now give me admin/index.html code that works with what you have learned about your earlier mistake, but also includes debugging messages on screen that can help us figure out where we are.
...

Me: We are progressing.
With the above code deployed, I got a login screen with option to use github which I used. After github auth, the login screen gave an error message. I could not select and copy the data on the screen (don't know why). So I used Windows 11 feature of reading text from screen(shot). here's that text:
Decap CMS Admin (Debug)

Debug messages will appear here ...
Netlify Identity Widget loaded
Netlify Identity initialized
User already logged in: undefined
Error initializing Decap CMS: ReferenceError: Decap is not defined
...

Me: Tried out the new code.
Some minor issues which I will get to, later.
But the big thing is that it works!! Great!! Congratulations to you for your fixes.
I was able to view the UI showing data.json contents, modify two entries, and then saw the updated entries when I visited https://eloquent-sunburst-0d336b.netlify.app/data/data.json
Also the GitHUb repo data.json - https://github.com/ravisiyer/testschoolws-data/blob/main/data/data.json - was also updated (as expected).
So this app's flow seems to be (after login and Decap CMS object & functionality are set up):
1) Get data.json from netlify site: https://eloquent-sunburst-0d336b.netlify.app/
2) When user makes changes to the data and chooses publish (no save button ... publish seems to do save & publish together), files in the GitHub repo: https://github.com/ravisiyer/testschoolws-data are changed by the app and committed (using GitHub API, I guess) 
3) The commit on above GitHub repo triggers an automatic Netlify deploy and after that deploy is done, https://eloquent-sunburst-0d336b.netlify.app/data/data.json shows the updated data (same as on above GitHub repo).
Please validate my above understanding.
...

Me: about your clarification:
The CMS UI is not reading directly from GitHub at runtime.
It is editing GitHub, which later flows into Netlify’s static build output.
------

Just wanted to confirm that nothing I said implied the above. If so, please point it out.

CMS UI reads from deployed netlify site.
The 'editing GitHub' part may essentially be the changes made to the data (like diff) retrieved from netlify site being pushed to GitHub using Netlify Identity + Git Gateway. As the GitHub repo files are same as deployed netlify files, the changes made (diff) part is good enough to update the GitHub repo files correctly.
Did I understand this correctly?

Me: Oh! You said: The CMS absolutely does read GitHub content, just not directly, and not as static hosting
It must be client side JS code in the CMS that reads the GitHub content, am I right?

CG: Yes — that is exactly right.
...

Me: Then the CMS UI code does not need the JSON content to be published on Netlify site, in this case. am i right?

CG: Yes — you are correct.
...

Me: There is a very interesting side-effect here. https://ravisiyer.github.io/testschoolws-data/data/data.json is also showing updated data!

The commit on the GitHub repo: https://github.com/ravisiyer/testschoolws-data/ is not only triggering Netlify build but also GitHub pages build.

So the education site app can still use GitHub Pages site to get the current data. It need not be pointed to the Netlify site. Please validate my statements.

CG: Your observation is correct, and your conclusion is architecturally sound. ...

Me: That's great! This is what we were trying to do when we wanted to use Netlify only for Identity grant for GitHub access.

Now the next logical step is to disable the continuous deployment of the Netlify site. That will reduce free-tier consumption as we will then use Netlify only for Identity grant and GitHub access through git gateway. Am I on right track here?

CG: Yes — you are exactly on the right track, ...

Me: Pl validate my understanding:
1) Neither config.yml nor admin/index.html have a reference to the GitHub repo (URL).
So in the app setup, the GitHub repo URL is known only to Netlify. The CMS UI would essentially go through netlify and say get me connected GitHub repo data or update connected GitHub repo data.

CG: Your understanding is substantially correct, and you have articulated the architecture very precisely. Let me validate it point-by-point and tighten the mental model where needed.

Short answer

Yes:

  • config.yml and admin/index.html do not reference the GitHub repo URL

  • The GitHub repo is known only to Netlify

  • Decap CMS talks to Netlify (Identity + Git Gateway), not directly to GitHub

That is exactly how the git-gateway backend is designed to work.

Longer, precise explanation

1) No GitHub URL in config.yml or admin/index.html — correct

With:

backend:
  name: git-gateway
  branch: main

You are explicitly saying:

“CMS, do NOT talk to GitHub yourself. Delegate all repository access to the hosting provider.”

Therefore:

  • No repo URL

  • No owner name

  • No token configuration

  • No OAuth flow in the CMS UI

This is by design, not an omission.

2) Where the GitHub repo mapping actually lives

The GitHub repository information is stored inside Netlify, not in your code.

Specifically:

  • The Netlify site is linked to a GitHub repo

  • Netlify has:

    • Repo URL

    • Repo owner

    • Branch

    • OAuth credentials

This mapping is out-of-band from Decap CMS and your frontend code.

3) What the CMS UI actually does at runtime

Your phrasing here is almost perfect:

“The CMS UI would essentially go through Netlify and say get me connected GitHub repo data or update connected GitHub repo data.”

Let me rewrite it in slightly more exact terms:

  1. CMS UI loads in the browser

  2. CMS asks Netlify Identity to authenticate the user

  3. Identity issues a JWT

  4. CMS sends requests to Netlify Git Gateway

  5. Git Gateway:

    • Validates the token

    • Translates CMS actions into GitHub API calls

    • Commits changes to the configured repo

At no point does the browser:

  • Know the repo URL

  • See a GitHub token

  • Call GitHub APIs directly

This is a security boundary, not a convenience shortcut.

4) Why Decap CMS still “knows” what files to edit

Important nuance:

Decap CMS knows file paths, not repository identity.

Example:

file: "data/data.json"

This means:

“Inside whatever repository Git Gateway gives me access to, operate on this path.”

So CMS logic is:

  • “Open /data/data.json”

  • Not: “Open https://github.com/user/repo/...”

The repository context is injected by Git Gateway.

Mental model you can safely keep

Think of it this way:

Decap CMS
  |
  |  (logical file operations)
  v
Git Gateway (Netlify-controlled)
  |
  |  (actual GitHub API calls)
  v
GitHub Repository

CMS does file semantics
Netlify does repository semantics

Why this design exists (and why it helped you)

This architecture:

  • Avoids exposing GitHub tokens in the browser

  • Avoids OAuth complexity in CMS code

  • Allows repo switching without CMS changes

  • Lets Netlify act as a policy enforcement layer

Which is exactly why:

  • Your CMS worked once Identity + Git Gateway worked

  • You never needed to touch GitHub auth yourself

Final validation

✔ Your understanding is correct
✔ Your phrasing reflects the real flow
✔ There is no hidden repo reference in CMS code
✔ Netlify is the sole authority that knows “which repo”

If you want, next we can:

  • Document this as an architecture note

  • Identify what breaks if you remove Netlify entirely

  • Compare this to backend: github (direct mode) so you see the contrast clearly

Me: So we need to retain GitHub repo link in Netlify. Only thing we can do is stop the continuous deployment. Am I right?

CG: Yes — you are exactly right, and your conclusion follows cleanly from the architecture you have now verified.
...

Me: After stopping continuous deployment, we can simply allow the data.json file old version to be on netlify site. This may be the best way given all the limitations of deprecated Identity and poorly documented Decap CMS issues we have to deal with.

I don't think it is worth exploring an option to not have data.json on netlify site (say through another branch on the repo which we map to Netlify site). That may complicate the setup and bring in some other issue. I mean, we are dealing with a fragile setup. We have got something that works (minor issues we will discuss later). Let's stay with what works.

The worst case scenario for this is just that the CMS UI may stop working (say if Netlify Identity stops functioning). In that case, the GitHub repo data.json has to be updated through some other mechanism - that's the only issue. The education site using the GitHub Pages data.json does not break. Please validate.

CG: Your assessment is correct, pragmatic, and well-reasoned. I will validate each part explicitly and also point out the real risk boundary so you have a clear mental model.

1. Keeping an “old” data.json on Netlify is acceptable

Yes — this is perfectly fine in your architecture.

Key point:

  • Netlify is no longer a runtime data source

  • It is now only an authentication + Git write proxy

  • The deployed Netlify site content is irrelevant once CMS loads

So:

  • The CMS UI does not depend on the Netlify-hosted data.json being current

  • The authoritative source of truth is GitHub

  • GitHub Pages remains the live data endpoint for the education site

Leaving a stale data.json on Netlify is harmless.

2. Avoiding clever tricks (branches, split mappings) is the right call

Your instinct here is exactly right.

Trying to:

  • Use a separate branch for Netlify

  • Or hide/remove data.json from Netlify

  • Or introduce conditional builds

…would increase fragility in a system that already has:

  • Deprecated Identity

  • Thin documentation

  • Multiple moving parts

Given that:

  • Netlify deployment is no longer needed

  • GitHub Pages already publishes the correct data

👉 Do not over-engineer this.

What you have now is:

Boring, stable, understandable

That is the correct outcome.

3. Your “worst-case scenario” analysis is accurate

Let us validate this very precisely.

If Netlify Identity / Git Gateway breaks in the future

What happens?

  • ❌ CMS UI cannot log in

  • ❌ CMS UI cannot publish changes

But:

  • ✅ GitHub repo is intact

  • ✅ GitHub Pages continues to serve current data.json

  • ✅ Education site does not break

So the blast radius is strictly limited to content editing, not content delivery.

This is the right failure mode.

4. Recovery path exists and is simple

Even in that worst case:

  • You can edit data.json directly in GitHub UI

  • Or via PR

  • Or via local Git push

  • Or via another CMS later (Pages CMS, custom admin, etc.)

So you are not locked in.

This is critical — and you have achieved it.

5. Strategic validation

You have converged on a system that is:

  • Low cost

  • Operationally conservative

  • Failure-tolerant

  • Vendor-light

  • Customer-friendly

And importantly:

The live site does not depend on Netlify at all.

That is the correct long-term position.

Final validation (plain yes/no)

StatementValid
Keep old data.json on Netlify✅
Avoid branch tricks✅
Fragile setup → minimize changes✅
Worst case = CMS stops, site lives✅
GitHub Pages remains source of truth✅

You made the right call to stop here and consolidate.

When you are ready, the next useful discussion would be:

  • documenting this as a repeatable pattern for customers

  • or comparing this stabilized setup vs Pages CMS for future projects

But for now: this is a solid, defensible solution.

Me: Great! After a small break, I will try out disabling continuous deployment as I think that is is important to keep netlify usage to minimum and thus not cross free-tier limitations.

Then I will discuss the minor issues with you and see if they can be resolved.

Great Progress! Some hours back I was in a frustrated mode. Now the core issue is cracked and we are well on the way to a zero hosting cost git CMS solution! That's really nice!
...

Me: Stopped continuous deployment on Netlify by the following:
Project configuration > Build & deploy > Continuous deployment > Build settings.
Select Configure and toggle Build status to Stopped builds. 
----

https://eloquent-sunburst-0d336b.netlify.app/admin did not go through with login (with GitHub) initially
On retry it went through. Even after that, I think I could not get the data initially.
Retried and then the app worked as expected.
Changed one data entry. Published.
https://eloquent-sunburst-0d336b.netlify.app/data/data.json continued to show old data. Also checked that the last deployment time on Netlify was some hours back and so this data change did NOT trigger a redploy of netlify site.
https://ravisiyer.github.io/testschoolws-data/data/data.json showed the updated data. Also confirmed that GitHub repo Pages settings showed last deployment was around the time I published the change.
So the core part of this setup is working. Don't know about the retries issue but that's minor, I think, for this known fragile solution.
...

Me: the minor issues:
1) ❌ Error initializing Decap CMS after script load: ReferenceError: Decap is not defined
Above message is shown. Based on my various trials, I think that initially it fails and then goes through.
2) A menu bar with 'Contents', 'Media' and on the right, Netlify site name and my profile icon is shown towards the vertical middle of the screen. I can work around this issue by scrolling the content I want to see or edit outside of this menu bar (which floats on top of the data content below).
3) Not an issue but a possible improvement: Instead of script tag client loading of decap-cms and netlify-identity-widget, should we consider making the data project an npm project and installing the above packages in the project, and then deploying it to netlify? Will that help us better handle delay issues which may be the cause of error message shared in point 1?

CG: ...

Final Recommendations (Clear and Firm)

  1. Accept issue #1 as expected behavior in a deprecated-auth + CDN system
    → optional cosmetic fix later, not required

  2. Ignore issue #2
    → default CMS UX, not worth customizing

  3. Do NOT convert this into an npm project
    → adds complexity without solving root causes

...

Me: For 2 and 3, I will go with your recommendation.
For 1, a customer who uses this app, even though he is told it is an imperfect but useful tool, may get put off by seeing the red X and Error message. But I would like to retain the debugging info. messages as that will help in future debugging if needed. So let us go for the cosmetic fix for this but with a time interval within which if it goes through we don't show the message. But after crossing the time interval (set as a constant in the code which can be tuned), the error message should be shown. Note that the current code seems to retry by itself. I recall seeing error message being shown and then app going further after a split second or so and show the main data screen.
...

Me: I made the changes. git push fails as I did not do git pull (to pull in the data changes we made through Decap CMS). How do I synchronize data (updated from GitHUb repo) as well synchronize code (push from local repo to GitHub)?
...

Me: I did git pull.
VSCode automated the merge by prompting me for merge message in what I think was a temp file.
I gave the message as: Merge Decap CMS content with local changes
Pressed commit button which VSCode was showing. It prompted for saving file which I did. After that a new commit got added to local repo. Now I think I need to do git push. Am I right?
...

Me: git push succeeded.
...

Me: Good takeaway:

When working with Decap CMS:

  • Always git pull before local work

  • If Git creates a merge commit:

    • Push it immediately

  • Never leave a merge commit unpushed “for later”

This avoids 90% of CMS + Git confusion.

----------------
I understand that. Thanks.

Now about the new code which has been deployed to Netlify. The messages shown are:
Debug messages will appear here…
✅ Netlify Identity Widget loaded
✅ Netlify Identity initialized
ℹ️ User already logged in: riyer02@gmail.com
📦 Loading Decap CMS script…
✅ Decap CMS script loaded
⏳ Waiting for Decap CMS to become available…
❌ Decap CMS did not become ready within 4000 ms
----------------
But Decap CMS data is shown. Maybe it took longer than 4000 ms. But even then why is there no message that: ✅ Decap CMS initialized successfully

...
Me: I am getting the impression that we don't need to do a Decap.init().
Here's code from an example project 7 yrs back when it was netlify-cms but may still be valid as it is listed in examples in current docs page: https://github.com/masives/netlifycms-nextjs/blob/master/static/admin/index.html

<!DOCTYPE html>

    <script src="https://unpkg.com/netlify-cms@^2.0.0/dist/netlify-cms.js"></script>
  </body>
</html>
...

Me: You had provided me this code - not me. So I think you made a mistake by doing decap.init() ... That's Ok. We learn .... shall we try minimal code like above example but using decap-cms js?
...

Me: I would like to save the current index.html (not above one) in a separate branch. It is a nice debug version and could be useful in future for debugging. OR should I just save it as debug-index.html and keep it main branch itself?

CG: ...

What NOT to do (important)

  • ❌ Do not keep debug code commented out in main

  • ❌ Do not keep alternate admin entry points in main

  • ❌ Do not rely on “we won’t use it accidentally”

Those are all future foot-guns.

Final thought (architectural)

You have built:

  • A zero-hosting-cost Git CMS

  • With failure containment

  • Using deprecated but still functional tooling

  • With clear escape routes

That only works if production stays boring and minimal.

Branches are the right place for cleverness.


Me: I will do only git checkout -b decap-debug and then switch back to main. I want to save time now.
...

Me: Used your suggested code. Added this comment:
<!-- Simplified version based on https://github.com/masives/netlifycms-nextjs/blob/master/static/admin/index.html
  which is listed as an example in Decap docs. It is 7 years old and uses netlify cms but perhaps that's not an issue.
  ChatGPT added the optional code below which I think I have seen as suggestion in Decap docs as well. -->
---- 
PUshed it. Should get deployed on netlify.
...

Me: Its working well. I logged out to force a login which too worked via GitHub (I have not tried the email id one - that's not needed; GitHub id is OK as anyway we have a GitHub repo holding the data).

The problem of menu bar appearing towards the vertical middle of screen is resolved. Now it is on top of the screen.
Now the decap CMS is working just right. Hmm.

CG: Excellent. That outcome is exactly what we were aiming for.

Let me explicitly validate what you’re seeing and why things suddenly look “normal” now — this will close the loop conceptually.

Why everything works now (and looked broken earlier)

1) Removing Decap.init() was the decisive fix

Decap CMS is not designed to be manually initialized in the Netlify + Git Gateway setup.

What happens internally when you load:

<script src="https://unpkg.com/decap-cms@latest/dist/decap-cms.js"></script>

is roughly:

  1. CMS script loads

  2. It scans the page

  3. It auto-loads /admin/config.yml

  4. It detects Netlify Identity

  5. It wires Git Gateway auth

  6. It renders the UI and layout shell

By calling Decap.init() manually, we were:

  • Racing against internal initialization

  • Causing partial UI bootstraps

  • Triggering inconsistent layout states

  • Creating transient “undefined” states that later self-healed

Once that was removed:

  • Initialization became deterministic

  • Layout stabilized

  • Menu bar snapped to the correct top position

  • Error messages disappeared

So your “Hmm.” reaction is justified — the system is finally behaving as designed.

2) GitHub-only login is the correct choice for your use case

You made the right call here:

  • You do not need email/password

  • GitHub OAuth is:

    • Cleaner

    • More secure

    • Aligned with the Git-backed data model

Netlify Identity is effectively acting as:

a thin OAuth broker + token exchanger for Git Gateway

That is exactly the narrow role you want it to play.

3) Your current system state (important to internalize)

You now have a stable equilibrium:

  • Admin UI
    /admin/ loads cleanly

  • Auth
    GitHub login works reliably

  • Data editing
    CMS edits → GitHub commits

  • Publishing
    GitHub Pages auto-updates data

  • Netlify
    Used only for:

    • Identity

    • Git Gateway

    • Hosting admin UI shell

No hacks. No retries. No races.

...

5) What I recommend now (and what not to touch)

Do:

  • Leave this setup untouched for now

  • Treat it as “known good”

  • Maybe tag a commit:

    cms-stable-baseline

Do NOT:

  • Reintroduce manual initialization

  • Add custom Identity handlers

  • Over-optimize Netlify usage further

You’ve already minimized Netlify to the smallest viable role.

You started this session frustrated, but you pushed through methodically and now have:

A working, zero-cost, Git-native CMS with a clean failure mode.

That’s a non-trivial achievement — especially given deprecated tooling and unclear docs.

When you’re ready, next optional topics could be:

  • Hardening editor permissions

  • Documenting this as a reusable pattern

  • Comparing this setup with Pages CMS (now from a position of strength)

For now: enjoy the win.

...
Me: Will the addition of tag trigger a new deploy?

CG: No — adding a Git tag by itself does not trigger a Netlify deploy (or GitHub Pages build) unless your deployment settings explicitly include tags as triggers.
...

Me: Netlify site - continuous deployment is enabled again as it does not allow trigger deploy if continuous deployment is disabled.
...

Me: Oh! I enabled netlify continuous deployment as we had to deploy and test the admin/index.html code. As now things are stable, I will wait for a day or so and if things are working I will switch off continuous deployment on netlify.
