Firebase Operations

This action allows you to:

• Set values into your firebase database (realtime or firestore) from and based on your current build.
• Retrieve a value from realtime DB and set as output for subsequent step logic.

Build inspired by https://github.com/w9jds/firebase-trigger.git

Inputs

• credentials - Required This action uses firebase admin, so you need to provide a service account json object for proper authentication.
• databaseUrl - Required Database Url you are trying to connect to. It is usually something like: https://[project_id].firebaseio.com
• databaseType - Optional The database you want to connect to. Defaults to realtime, Accepts realtime and firestore.
• path - Required Path to the field you want to modify. If you are using firestore, this is the collection path.
• doc - Required for Firestore Document you want to modify. Uses set, so it will write/overwrite the whole file.
• value - Optional Value you would like to set. Defaults to Date.now() timestamp. If you are using Firestore this MUST be a JSON Object.
• operation - "read"

Usage

For "write" operation: Writes to a realtime database, and sets the lastRelease to a Date.now() timestamp.

notify:
  runs-on: ubuntu-latest
  name: Nofity
  needs: [build, deploy]
  steps:
    - name: Update latest version in realtime database
      uses: w9jds/firebase-trigger@master
      with:
        credentials: ${{ secrets.FIREBASE_CREDENTIALS }}
        databaseUrl: https://[project_id].firebaseio.com
        path: version/lastRelease
        operation: read | write
        value: "some data from other step"

For "read" operation: Retrieves value and sets output as retrievedValue which can be used in subsequent steps - e.g. ${{ steps.whatever-step-id.outputs.retrievedValue }}. The output is a JSON string.

Recommendation

You should store the Service Account JSON into a secret on your repo. Also, this can be very powerful if you start passing outputs from other jobs into this one to write values.
