Pull request previews for Hugo

Here's a step-by-step guide to help you install PushPreview in your Hugo project.

Prerequisites

Before you begin, you'll need to have the following:

• A PushPreview account. If you don't have one, sign up for free.
• A Hugo site created.

1. Add the workflow to your repository

To set up the PushPreview workflow in your Hugo project:

1. Go to the .github/workflows directory in your Hugo repository.

2. Create a new file named pushpreview.yml.

3. Copy the following content into pushpreview.yml:

   name: PushPreview
   
   on:
     pull_request_target:
       types:
         - labeled
   
   jobs:
     preview:
       runs-on: ubuntu-latest
       if: github.event.label.name == 'preview'
       steps:
         - uses: actions/checkout@v3
         - name: Comment
           run: |
             gh pr comment ${{ github.event.pull_request.number }} --repo ${{ github.repository }} --body "⚙️ Hang tight! PushPreview is currently building your preview. We'll share the URL as soon as it's ready."
           env:
             GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
   
         - uses: actions/setup-node@v3
           with:
             node-version: 18
   
         - name: Set BASE_URL
           run: echo "BASE_URL=/github/${{ github.repository }}/${{ github.event.number }}/" >> $GITHUB_ENV
   
         - name: Build site
           run: |
             cd docs
             yarn install --frozen-lockfile
             yarn build
   
         - name: Generate preview
           uses: PushLabsHQ/pushpreview-action@1.0.6
           with:
             source-directory: ./docs/build
             github-token: ${{ secrets.GITHUB_TOKEN }}
             pushpreview-token: ${{ secrets.PUSHPREVIEW_TOKEN }}

4. Modify the Build site step to align with your Hugo build process. For example:

   - name: Build site
     run: |
       cd docs
       sudo apt-get install -y hugo
       hugo

5. Ensure the source-directory in the Generate preview step points to your Hugo build output folder, typically ./public:

   - name: Generate preview
     uses: PushLabsHQ/pushpreview-action@1.0.6
     with:
       source-directory: ./docs/public
       github-token: ${{ secrets.GITHUB_TOKEN }}
       pushpreview-token: ${{ secrets.PUSHPREVIEW_TOKEN }}

6. Save your changes and push the updated pushpreview.yml file to your repository.

2. Configure the GitHub secret

To configure the GitHub secret, follow these steps:

1. Generate a PushFeedback token. For more information, see Authentication.

2. Go to the Settings tab of your GitHub repository or organization.

3. In the Settings menu, navigate to Secrets and chose Actions.

4. Click on New repository secret or New organization secret, depending on your choice in the previous step.

5. Use the following details to create a new token:

   • Name: PUSHPREVIEW_TOKEN
   • Token: The token you have generated.

6. Click Add secret.

3. Verify the installation

To ensure proper functioning of the PushPreview integration in your GitHub repository, follow these steps:

1. Create a new pull request in your GitHub repository.

2. Add the preview label to your new pull request. If the label doesn’t exist, create a new one.

   

3. Wait briefly for PushPreview to process the pull request and post a comment in the pull request thread.

4. Look for a comment from PushPreview containing a preview link. Click this link to view the changes.

Congratulations on setting up PushPreview! Your users can now view live previews of changes in pull requests, enhancing collaboration and review efficiency.
