Docusaurus

This guide instructs you on how to integrate Decap CMS with Docusaurus.

Before you begin

Sign up for GitHub and Netlify.
Download Node.js version 14 or above.
Install the GitHub CLI.
Install and authenticate the Netlify CLI.

Create a new Docusaurus project

# 1. Use Docusaurus to create a site scaffold.
npx create-docusaurus@latest my-website classic

# 2. Run the development server.
cd my-website
npm run start

A browser window opens at http://localhost:3000.

The development server now serves your website at http://localhost:3000. As you edit the source files in /my-website/, you can visit http://localhost:3000 to preview your changes.

Push your project to GitHub

Decap CMS requires a backend to store content. Decap CMS supports using Git hosts, like GitHub or GitLab, as backends. This guide uses GitHub.

# 1. Initialize your local Git repository.  
git init

# 2. Rename your initial branch to match GitHub.
git branch -m main

# 3. Stage all your local files to your repository.
git add . 

# 4. Commit your staged changes.
git commit -m 'Initial commit'

# 5. Create a remote repository on GitHub using the GitHub CLI.
gh repo create my-website

Don't add a license or a .gitignore. Do add an "origin" git remote.

# 6. Update your remote repository with your staged changes. 
git push -u origin main

Publish your project using Netlify CLI

Connect Netlify CLI to your GitHub repository.
```
netlify init
```
Choose Create & configure a new site.
Choose your team and site name.
Choose yarn build for your build command.
Choose build for your deployment directory.

Choose the default option for everything else.

Your website is now deployed. Netlify provides you with a randomly generated domain name. Run netlify open --site to view your deployed site.

Add Decap CMS to your project

Before you begin

Remove all existing posts from /blog.
```
rm -rf ./blog/*
```
Create a new blog post post titled 2021-11-15-first-blog-post.md.
```
touch ./blog/2021-11-15-first-blog-post.md
```

Edit 2021-11-15-first-blog-post.md to look like this:

---
title: First Blog Post
slug: first-blog-post
tags:
  - foo
  - bar
authors:
  - name: Garrison McMullen
    title: Instruction Writer
    url: https://github.com/garrison0
    image_url: https://avatars.githubusercontent.com/u/4089393?v=4

Procedure

Create an admin directory inside static.
```
cd static
mkdir admin
```
In the admin directory, create a config.yml file and an index.html file.
```
cd admin
touch config.yml
touch index.html
```

Edit index.html to look like this:

<!doctype html>
<html>
<head>
  <meta charset="utf-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Content Manager</title>
</head>
<body>
  <!-- Include the script that builds the page and powers Decap CMS -->
  <script src="https://unpkg.com/decap-cms@^3.0.0/dist/decap-cms.js"></script>
</body>
</html>

index.html displays the Decap CMS admin interface. You'll use the admin interface to edit your blog posts.

Edit config.yml to look like this:

backend:
  name: github
  branch: main 
  repo: <your-github>/my-website

# These lines should *not* be indented
media_folder: "static/img" # Media files will be stored in the repo under static/images/uploads
public_folder: "/img/" # The src attribute for uploaded media will begin with /images/uploads

collections:
- name: blog
  label: "blog"
  folder: blog
  identifier_field: title
  extension: md
  widget: "list"
  create: true
  slug: "{{year}}-{{month}}-{{day}}-{{slug}}" # Filename template, e.g., YYYY-MM-DD-title.md
  fields:
    - { name: title, label: Title, widget: string }
    - { name: body, label: Body, widget: markdown }
    - { name: slug, label: Slug, widget: string }
    - label: "Tags"
      name: "tags"
      widget: "list"
    - label: "Authors"
      name: "authors" 
      widget: "list"
      fields:
        - { name: name, label: Name, widget: string }
        - { name: title, label: Title, widget: string } 
        - { name: url, label: URL, widget: string } 
        - { name: imageUrl, label: ImageURL, widget: string }

config.yml specifies what kind of content your blog posts have. The content specification enables Decap CMS to edit existing posts and create new ones with the same format. To learn more, read about Decap CMS' Configuration options.

Visit localhost:3000/admin
You can now view and edit 2021-11-15-first-blog-post.md through the admin interface. You can also create new blog posts.

Warning: Any changes you publish through the admin interface will only effect your remote GitHub repository. To retrieve these changes locally, git pull from your local repository.
Commit and push your new changes to your remote repository.
```
git add . 
git commit -m "Add Decap CMS"
git push
```
Netlify builds and deploys your new changes.

Add GitHub as an authentication provider

Before you can access /admin/ through your Netlify domain, you need to set up an authentication provider. The authentication provider allows Decap CMS to determine whether users have read and write access to /admin/. This guide uses GitHub credentials for authentication.

Configure GitHub

Create a new GitHub OAuth application.
Enter your Netlify domain as the Homepage URL.
Enter https://api.netlify.com/auth/done as the Authorization callback URL.
Click Register application.
Click Generate a new client secret.
Copy the provided client secret and client ID.

Configure Netlify

On Netlify, under Site Settings > Access control > OAuth > Authentication Providers, click Install provider.
Enter your client secret and client ID from GitHub.
Click Install.

🎉 All done! Now you can access the admin interface through your Netlify URL.
