Decap CMS setup

  1. Create an admin directory inside the src
  2. Create an uploads directory inside the root of your project
  3. Add index.html, index.js and a config.yml file to your admin directory

Your index.html should look like this:

<!DOCTYPE html>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Decap CMS</title>
    <script src="index.js" type="module"></script>

Your index.js should look like this:

import CMS from "decap-cms"

Your config.yml for GitHub should look like this:

  name: git-gateway
  branch: main # Branch to update (optional; defaults to master)

media_folder: "static/uploads"
public_folder: "/uploads"

  - name: "posts"
    label: "Posts"
    folder: "posts"
    create: true
    slug: "{{slug}}"
      - {label: "Title", name: "title", widget: "string"}
      - {label: "Excerpt", name: "excerpt", widget: "string"}
      - {label: "Publish Date", name: "date", widget: "datetime"}
      - {label: "Body", name: "body", widget: "markdown"}

Push to GitHub

It's now time to commit your changes and push to GitHub.

git init
git add .
git commit -m "Initial Commit"
git remote add origin
git push -u origin main

Add your repo to Netlify

Go to Netlify and select 'New Site from Git'. Select GitHub and the repository you just pushed to. Click Configure Netlify on GitHub and give access to your repository. Finish the setup by clicking Deploy Site. Netlify will begin reading your repository and starting building your project.

Enable Identity and Git Gateway

Netlify's Identity and Git Gateway services allow you to manage CMS admin users for your site without requiring them to have an account with your Git host or commit access on your repo. From your site dashboard on Netlify:

  1. Go to Settings > Identity, and select Enable Identity service.
  2. Under Registration preferences, select Open or Invite only. In most cases, you want only invited users to access your CMS, but if you're just experimenting, you can leave it open for convenience.
  3. If you'd like to allow one-click login with services like Google and GitHub, check the boxes next to the services you'd like to use, under External providers.
  4. Scroll down to Services > Git Gateway, and click Enable Git Gateway. This authenticates with your Git host and generates an API access token. In this case, we're leaving the Roles field blank, which means any logged in user may access the CMS. For information on changing this, check the Netlify Identity documentation.

Start publishing

It's time to create your first blog post. Login to your site's /admin/ page and create a new post by clicking New Blog. Add a title, a date and some text. When you click Publish, a new commit will be created in your GitHub repo with this format Create Blog “year-month-date-title”.

Then Netlify will detect that there was a commit in your repo, and will start rebuilding your project. When your project is deployed you'll be able to see the post you created.

Your basic blog scaffold is done, now you can query data from the GraphQL server just like you're working with the filesystem. For more info read querying data.
