Refined Cloudflare Pages Action

An opinionated fork of the official Cloudflare Pages Action.

A GitHub Action for creating Cloudflare Pages deployments, using Direct Upload with Wrangler.

Advantages over official solutions

  • ✅ Generated build summaries
  • ✅ Deploy multiple sites from a single monorepo
  • ✅ Builds site previews of PRs from forked repositories, a known issue with official solutions
  • ✅ GitHub Deployments on PRs from forks

Usage

Important

This action entirely replaces the Cloudflare Pages GitHub integration. Before continuing, you should disable the automatic builds made by Cloudflare for the repository you are applying this action to.

  1. Locate your Cloudflare account ID.
  2. Generate an API token.
  3. Add the Cloudflare account ID and API token as secrets to your GitHub repository.
  4. Create a .github/workflows/publish.yml file in your repository:
on:
  push:
    branches:
      - main

jobs:
  publish:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      deployments: write
    name: Publish to Cloudflare Pages
    steps:
      - name: Checkout
        uses: actions/checkout@v3

      # Run a build step here if your project requires one
      # ...

      - name: Publish to Cloudflare Pages
        uses: AdrianGonz97/refined-cf-pages-action@v1
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          githubToken: ${{ secrets.GITHUB_TOKEN }}
          projectName: YOUR_PROJECT_NAME
          directory: YOUR_BUILD_OUTPUT_DIRECTORY
          # Optional: Supply a deployment name if you want to have GitHub Deployments triggered
          deploymentName: Production
          # Optional: Switch what branch you are publishing to.
          # By default, this will be the branch which triggered this workflow
          branch: main
          # Optional: Change the working directory
          workingDirectory: my-site
          # Optional: Change the Wrangler version, allows you to point to a specific version or a tag such as `beta`
          # Specifying an empty string ('') will omit the version specifier.
          wranglerVersion: '3'
  1. Replace YOUR_PROJECT_NAME and YOUR_BUILD_OUTPUT_DIRECTORY with the appropriate values to your Pages project.

And you're ready to go!

Tip

Be sure to check out the Enabling PR Previews from Forks section if you're interested in enabling this particular feature.

Get account ID

To find your account ID, log in to the Cloudflare dashboard > select your zone in Account Home > find your account ID in Overview under API on the right-side menu. If you have not added a zone, add one by selecting Add site.

If you do not have a zone registered to your account, you can also get your account ID from the pages.dev URL. E.g: https://dash.cloudflare.com/<ACCOUNT_ID>/pages

Generate an API Token

To generate an API token:

  1. Log in to the Cloudflare dashboard.
  2. Select My Profile from the dropdown menu of your user icon on the top right of your dashboard.
  3. Select API Tokens > Create Token.
  4. Under Custom Token, select Get started.
  5. Name your API Token in the Token name field.
  6. Under Permissions, select Account, Cloudflare Pages and Edit:
  7. Select Continue to summary > Create Token.

Add Cloudflare credentials to GitHub secrets

  1. Go to your project’s repository in GitHub.
  2. Under your repository’s name, select Settings.
  3. Select Secrets and variables > Actions > New repository secret.
  4. Create a secret and put CLOUDFLARE_ACCOUNT_ID as the name with the value being your Cloudflare account ID.
  5. Create another secret and put CLOUDFLARE_API_TOKEN as the name with the value being your Cloudflare API token.

Disabling the Cloudflare Pages GitHub integration

If you have already connected your repository to the Cloudflare Pages GitHub integration, you'll need to disable it.

  1. Go to your project’s repository in GitHub.
  2. Under your repository’s name, select Settings.
  3. Select GitHub Apps, and next to Cloudflare Pages, select Configure
  4. Under Repository access, select Only select repositories, and remove your repository.

Enabling PR Previews from Forks

If your site does not use/have any runtime secrets in your preview environment on Cloudflare, then it should be fine to use as-is. We use this method in shadcn-svelte and its implementation can be found here.

Example: Preview Deployment with NO RUNTIME/BUILD-TIME SECRETS

First we'll build the project in an unprivileged environment where secrets are not exposed. This allows use to safely run untrusted code:

# build-preview.yml
name: Build Preview Deployment

on:
  pull_request:
    types: [opened, synchronize]

jobs:
  build-preview:
    runs-on: ubuntu-latest
    name: Build Preview Site and Upload Build Artifact
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      # Run your install/build steps here
      # ...

      # Build example
      - name: Build site
        run: pnpm build
        env:
          # if you need environment variables that are _NOT secrets_, apply them here during build
          # using GH Action variables
          SOME_ENV_VAR: ${{ vars.SOME_ENV_VAR }}

      # Uploads the build directory as a workflow artifact
      - name: Upload build artifact
        uses: actions/upload-artifact@v4
        with:
          name: preview-build
          path: YOUR_BUILD_OUTPUT_DIRECTORY

Then we'll deploy the project to Cloudflare in a privileged environment where we can safely use secrets (i.e. your cloudflare credentials):

# deploy-preview.yml
name: Upload Preview Deployment
on:
  workflow_run:
    workflows: ['Build Preview Deployment']
    types:
      - completed

permissions:
  actions: read
  deployments: write
  contents: read
  pull-requests: write

jobs:
  deploy-preview:
    runs-on: ubuntu-latest
    if: ${{ github.event.workflow_run.conclusion == 'success' }}
    name: Deploy Preview to Cloudflare Pages
    steps:
      # Downloads the build directory from the previous workflow
      - name: Download build artifact
        uses: actions/download-artifact@v4
        id: preview-build-artifact
        with:
          name: preview-build
          path: build
          github-token: ${{ secrets.GITHUB_TOKEN }}
          run-id: ${{ github.event.workflow_run.id }}

      - name: Deploy to Cloudflare Pages
        uses: AdrianGonz97/refined-cf-pages-action@v1
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          githubToken: ${{ secrets.GITHUB_TOKEN }}
          projectName: YOUR_PROJECT_NAME
          deploymentName: Preview
          directory: ${{ steps.preview-build-artifact.outputs.download-path }}

If your project does use runtime secrets, then the deployment job can be fitted with an environment field that requires manual approval before each deployment.

Manual approval using environments needs to be setup at the repo level, as described in this Melt UI PR under the "Make the Preview environment protected" step.

Example: Preview Deployment WITH RUNTIME SECRETS 

# build-preview.yml
name: Build Preview Deployment

on:
  pull_request:
    types: [opened, synchronize]

jobs:
  build-preview:
    environment: Preview # The name of the environment that requires manual approval before each deployment
    runs-on: ubuntu-latest
    name: Build Preview Site and Upload Build Artifact
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      # Run your install/build steps here
      # ...

      # Build example
      - name: Build site
        run: pnpm build
        env:
          # If you need environment variables that are **NOT secrets**,
          # apply them here during build using GH Action Variables
          SOME_ENV_VAR: ${{ vars.SOME_ENV_VAR }}

      # Uploads the build directory as a workflow artifact
      - name: Upload build artifact
        uses: actions/upload-artifact@v4
        with:
          name: preview-build
          path: YOUR_BUILD_OUTPUT_DIRECTORY
# deploy-preview.yml
name: Upload Preview Deployment
on:
  workflow_run:
    workflows: ['Build Preview Deployment']
    types:
      - completed

permissions:
  actions: read
  deployments: write
  contents: read
  pull-requests: write

jobs:
  deploy-preview:
    runs-on: ubuntu-latest
    if: ${{ github.event.workflow_run.conclusion == 'success' }}
    name: Deploy Preview to Cloudflare Pages
    steps:
      # Downloads the build directory from the previous workflow
      - name: Download build artifact
        uses: actions/download-artifact@v4
        id: preview-build-artifact
        with:
          name: preview-build
          path: build
          github-token: ${{ secrets.GITHUB_TOKEN }}
          run-id: ${{ github.event.workflow_run.id }}

      - name: Deploy to Cloudflare Pages
        uses: AdrianGonz97/refined-cf-pages-action@v1
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          githubToken: ${{ secrets.GITHUB_TOKEN }}
          projectName: YOUR_PROJECT_NAME
          deploymentName: Preview
          directory: ${{ steps.preview-build-artifact.outputs.download-path }}

In the off chance that you need build-time secrets (which you should try to avoid for previews), then you'll need to use the pull_request_target event with manual approvals before each deployment.

Important

With this method, each PR needs to be reviewed thoroughly before deployment approval to ensure that secrets are not being exposed via malicious code. Use with discretion.

Example: Preview Deployment WITH BUILD-TIME SECRETS 

name: Preview Deployment
on:
  pull_request_target:

jobs:
  deploy-preview:
    environment: Preview # The name of the environment that requires manual approval before each deployment
    runs-on: ubuntu-latest
    permissions:
      contents: read
      pull-requests: write
      deployments: write
    name: Deploy Preview to Cloudflare Pages
    steps:
      - uses: actions/checkout@v4
        with:
          ref: ${{ github.event.pull_request.head.ref }}
          repository: ${{ github.event.pull_request.head.repo.full_name }}

      # Run your install/build steps here
      # ...

      # Build example
      - name: Build site
        run: pnpm build
        env:
          SOME_SECRET: ${{ secrets.SOME_SECRET }} # Uses some secret during build

      - name: Deploy to Cloudflare Pages
        uses: AdrianGonz97/refined-cf-pages-action@v1
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          githubToken: ${{ secrets.GITHUB_TOKEN }}
          projectName: YOUR_PROJECT_NAME
          directory: YOUR_BUILD_OUTPUT_DIRECTORY
          deploymentName: Preview

Specifying a branch

The branch name is used by Cloudflare Pages to determine if the deployment is production or preview. Read more about git branch build controls.

If you are in a Git workspace, Wrangler will automatically pull the branch information for you. You can override this manually by adding the argument branch: YOUR_BRANCH_NAME.

Specifying a working directory

By default Wrangler will run in the root package directory. If your app lives in a monorepo and you want to run Wrangler from its directory, add workingDirectory: YOUR_PACKAGE_DIRECTORY.

Outputs

Name Description
id The ID of the pages deployment
url The URL of the pages deployment
alias The alias, if it exists, otherwise the deployment URL
environment The environment that was deployed to
