Abandoned

With the rollout of the new Firebase console, this buildpack no longer works. We do not have any plans to continue supporting this repo.

Heroku Buildpack for Firebase

This is an unofficial buildpack to automatically provision Firebase instances for Heroku apps.

Usage

1. Add this buildpack to an existing Heroku app:

# "-i 1" inserts this buildpack as the first buildpack to run, so that your
# Firebase is guaranteed to be available by the time your normal buildpack runs.
$ heroku buildpacks:add -i 1 https://github.com/casetext/heroku-buildpack-firebase \
  --app <your-app-name>

2. Set the config vars FIREBASE_ADMIN_USER and FIREBASE_ADMIN_PASS to a valid set of login credentials to Firebase.

3. Build your app as usual. When your buildpack runs, there will now be three environment variables set:

• FB_NAME: the randomly-chosen name of the Firebase, like few-melodic-winter
• FIREBASE_URL: the hostname of the Firebase, like few-melodic-winter.firebaseio.com
• FIREBASE_AUTH_SECRET: an authentication secret for the Firebase that you can use to generate JWTs of your own or just on its own as an administrative credential.

Custom auth config

The auth configuration (OAuth via Facebook/etc., users and passwords, etc.) of a Firebase cannot be changed without specialized tools.

If you would like to enable different authentication types for your new Firebase (which is the reason you aren't using firebaseio-demo.com to begin with), add a file named firebase-config.json to the root of your repo.

The default auth config looks like this. You can copy it out and change it as you need.

{
  "domains": [],
  "sessionLengthSeconds": 86400,
  "anonymous": {
    "enabled": false
  },
  "facebook": {
    "enabled": false,
    "key": "",
    "secret": ""
  },
  "github": {
    "enabled": false,
    "key": "",
    "secret": ""
  },
  "google": {
    "enabled": false,
    "key": "",
    "secret": ""
  },
  "password": {
    "enabled": false,
    "emails": {
      "password-reset": {
        "from": "@<YOUR_FIREBASE_NAME>.firebaseapp.com",
        "fromname": "",
        "replyto": "",
        "subject": "",
        "template": "Hello!\n\nIt looks like you've forgotten your password.\n\nUse the following temporary password within the next 24 hours to log in and update your account: %TOKEN%\n\nThanks!",
        "format": "plainText"
      }
    }
  },
  "twitter": {
    "enabled": false,
    "key": "",
    "secret": ""
  }
}

About buildpacks

For more information about using buildpacks on Heroku, see these Dev Center articles:

• Buildpacks
• Buildpack API

Locking to a buildpack version

In production, you frequently want to lock all of your dependencies - including buildpacks - to a specific version. That way, you can regularly update and test them, upgrading with confidence.

First, find the version you want from the list of buildpack versions. Then, specify that version with buildpacks:set:

heroku buildpacks:set https://github.com/casetext/heroku-buildpack-firebase#v1 -a my-app

Hacking

To make changes to this buildpack, fork it on Github. Push up changes to your fork, then create a new Heroku app to test it, or configure an existing app to use your buildpack:

# Create a new Heroku app that uses your buildpack
heroku create --buildpack <your-github-url>

# Configure an existing Heroku app to use your buildpack
heroku buildpacks:set <your-github-url>

# You can also use a git branch!
heroku buildpacks:set <your-github-url>#your-branch

Testing

The buildpack tests use Docker to simulate Heroku's Cedar-14 container.

Note that before you run the tests, you will need to have the environment variables FIREBASE_ADMIN_USER and FIREBASE_ADMIN_PASS set in the host machine's environment (i.e., the machine you're executing make test on).

To run the test suite:

make test

The tests are run via the vendored shunit2 test framework.
