This GitHub action manages Heroku review apps for your software delivery pipeline. This was born out of the frustration of not being able to use review apps for a long time and there's no timeline when Heroku will have this sorted. See status.heroku.com/incidents/2413 for more info.

This mimics 💯 how review apps work with the native Heroku integration.

• ⚙️ Focuses on automated preview deploy. You get the same automated preview deploy experience for your PRs.
• 🏎 Fast . No need to upload all your git info/metadata or history to Heroku.(coming soon - configure which files to omit from source code upload).
• 🧘🏽‍♀️ No fear of 3rd party having access to all your private GitHub data/repository.

Here's an example workflow that uses this action. This example workflow runs when you open (reopen), close, or push a new commit to your PR branch.

This action delete review apps when the associating PR is closed.

on:
  pull_request:
    types: [opened, reopened, closed, synchronize]

jobs:
  automate-review-app:
    runs-on: ubuntu-latest
    name: A job to create and delete review a review app
    steps:
      - name: Checkout
        uses: actions/checkout@v3
      - name: Deploy Heroku app
        uses: pmbanugo/[email protected] # Uses the action
        id: deploy
        with:
          api-key: ${{ secrets.HEROKU_API_KEY }}
          pipeline-id: ${{ secrets.HEROKU_PIPELINE_ID }}
          app-name-prefix: getting-started
          region: us
          use-app-json: true # Use this if your app contains app.json in the root directory
      - name: Get the review app url # Use the output from the `deploy` step
        run: echo "The URL is ${{ steps.deploy.outputs.url }}"
      - name: Comment on commit # Optional: You can use any action to comment on the PR
        uses: phulsechinmay/[email protected]
        with:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          COMMENT_IDENTIFIER: "Deploy"
          message: |
            I deployed a review app for you to try out this pull request 👇🏽

            Heroku App: ${{ steps.deploy.outputs.url }}

The action expects a few input parameters which are defined below.

• app-name-prefix (optional): Prefix for the app. This is should generally be the name of the pipeline e.g airtable prefix will produce soludo-pr-PR_NUMBER.herokuapp.com.
• api-key (required): Your Heroku API key
• pipeline-id (required): The id of the pipeline to deploy the review app to.
• region (optional): The region to deploy to. For example eu or us. Default: eu
• stack (optional): The Heroku stack to deploy and build with e.g heroku-18. Default: heroku-20. If the input use-app-json is true, the stack will be determined by what's in app.json, and if not present, the default on Heroku will be used.
• use-app-json (optional): Set up the initial build using the app.json in the root directory. Default: false.

I used a similar code for my private workflow since the removal of GitHub integration from Heroku. I decided to release this seeing that there's no clear indication as to when it'll be sorted. There are some edge cases that should be handled (proper error handling) but at the current release is not being done. I'll be making improvements in the coming days/weeks until Heroku restores their service (or until the community no longer needs this).

This action works well with most cases at the moment. If something is broken or you would extra features or configuration, feel free to create an issue.

To better support the maintenance and active development of this projects (as well as others), it'll be helpful if you sponsor me here on GitHub.
