How to Create a Blog with Quartz, GitHub, and Cloudflare

If you don't want to use Jekyll as your static site generator for GitHub Pages and you want to have a custom domain for your GitHub Pages. This post is for you!

0. Dependencies

• Find a package manager for your current system and become familiar with it. I will use brew since I'm on macOS.
• brew install node git gh or something similar for your package manager.
• Using gh or the GitHub cli makes working with GitHub easier.

1. Fork Quartz

• You can either use Quartz as a Template or Fork it.
  • Template: copy of Quartz as is, which might make keeping up with Quartz updates slightly difficult. Updates will probably need a copy and paste of Quartz at the root. Managing changes this way is difficult.
  • Fork: easier to sync changes from the source. Any changes or modifications you make to Quartz will become merge conflicts when an update happens, which are easier to manage with the right tools.
  • I recommend a Fork. After you click on Fork, STOP.

2. Name your Quartz Fork to initialize your GitHub Pages

• Since you can have only one public Fork of Quartz at a time, I used my Fork to create my GitHub Pages.
• Under the repo name after you click Fork, I entered ababber.github.io. When you name your Quartz Fork repo, replace ababber with your GitHub username, which initializes your GitHub Pages.
• According to GitHub, you only have one GitHub Page per username.
• Once the Fork is created. There are a few more steps before you're live.

3. Setup Quartz locally

# clone with git
git clone https://github.com/username/username.github.io.git

# 0. if you get an error, then use the GitHub 
# cli to login to GitHub on your command line
# with the following command: `gh auth login`

# 1. clone with the github cli:
# gh repo clone username/username.github.io 

# change directory into repo root
cd username.github.io

# install quartz dependencies
npm i

# initialize quartz and create an index.md
npx quartz create 

# select: Empty Quartz
# select: Treat links as relative paths

# cd into content/, which is where quartz will 
# look to create static pages 
cd content 

# create a test markdown file
touch test.md

# return to the repo root
cd ..

# this will build a preview of your blog
npx quartz build --serve

# 0. Ensure your browser allows http traffic

# 1. Once the build is done, go to http://localhost:8080
# in your browser.

# 2. In the left hand Explorer column, you should
# see test or the file created earlier.

4. Setup Deploy in Repo

• In your favorite code editor, create a file called deploy.yml.
  • I recommend vscode.
• In the hidden directory /username.github.io/.github/workflows/, add deploy.yml
• The content of deploy.yml is below:

name: Deploy Quartz site to GitHub Pages

on:
  push:
    branches:
      - v4

permissions:
  contents: read
  pages: write
  id-token: write

concurrency:
  group: "pages"
  cancel-in-progress: false

jobs:
  build:
    runs-on: ubuntu-22.04
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0 # Fetch all history for git info
      - uses: actions/setup-node@v4
        with:
          node-version: 22
      - name: Install Dependencies
        run: npm ci
      - name: Build Quartz
        run: npx quartz build
      - name: Upload artifact
        uses: actions/upload-pages-artifact@v3
        with:
          path: public

  deploy:
    needs: build
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    runs-on: ubuntu-latest
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4

5. Configure GitHub for Quartz Deploy

• Go to your Quartz Fork, which will be something like: https://github.com/username/username.github.io.
• Click on the Settings tab for the repo.
• In the left hand column, click on Pages.
• Under Build and deployment in the Source drop down menu, select GitHub Actions
• We've already setup the workflow with deploy.yml.
• At the bottom, select Enforce HTTPS if not selected.

6. Sync Content

• In quartz.config.ts, change the baseUrl property to your GitHub Pages root domain, which should be something like username.github.io.

# check if everything looks fine
npx quartz build --serve

# commit the changes and deploy your quartz site
npx quartz sync

# 0. it will take a few minutes for your page to 
# go live at username.github.io

# 1. in your username.github.io Actions tab, you 
# can check the status of your build and deploy, 
# any errors will be listed here

7. Setup Custom Domain with cloudflare

• Go to cloudflare
• Create an account.
• Search for a domain name.
• Register it (prices will vary depending on the domain name).
• From your Account Home go to the domain you just created.
• Click on DNS and ensure you're in the Records section.
• Select Add record:
  • Type: CNAME
  • Name: @
  • Target: username.github.io
  • Select Save
• Select Add record:
  • Type: CNAME
  • Name: www
  • Target: username.github.io
  • Select Save
• For all the records that were created, ensure the Proxy status is OFF, we will enable this later.
• On the left hand column of your custom domain page, click on SSL/TLS.
• Ensure you are on the Overview section of SSL/TLS.
• Click on Configure.
• By default cloudflare sets Custom SSL/TLS to Flexible. Change this to Full.
  • We need to do this because username.github.io is being served to cloudflare over HTTPS by GitHub.
  • If we don't do this then your GitHub page may become unreachable and report the following error: ERR_TOO_MANY_REDIRECTS. This is caused by a conlict with the Custom SSL/TLS Flexible setting and the Github Pages Enfore HTTPS setting which creates an unexpected feedback loop.

8. Set GitHub Pages Custom Domain

• Verify your custom domain with the following instructions.
• Go to https://github.com/username/username.github.io.
• Click on your repo Settings tab.
• In the left hand column, click on Pages.
• Under Custom domain, enter your customdomain.com root. Don't include the protocol or a subdomain.
• Click on Save.
• Wait on this page for GitHub to perform checks. If everything was setup correctly, DNS check successful will appear.

9. Final Things to Configure

• Go to your repo on your local machine.
• In quartz.config.ts change the baseUrl property to your customdomain.com root.
• Sync changes to GitHub with: npx quartz sync.
• Wait for the build and deploy to finish in your username.github.io repo.
• Check if your customdomain.com is live.
• Troubleshooting can be done in your username.github.io repo Actions and Settings --> Pages tabs.
• Once everything is live and working correctly, go back to your cloudflare account.
  • Log in.
  • Go to your customdomain --> DNS --> Records
  • Set Proxy status to ON for the previously created CNAME records.
