Firebase Functions Interop Library for Dart #

This library provides JS bindings for Firebase Functions Node SDK. It also exposes a convenience layer to simplify writing Cloud Functions applications in Dart.

Please note that it's currently a proof-of-concept-preview version so it lacks many features, tests and documentation. But, it's already fun to play with!

Usage #

Make sure you have Firebase CLI installed as well as a Firebase account and a test app. See Getting started for more details.

1. Create a new project directory and initialize functions: #

$ mkdir myproject
$ cd myproject
$ firebase init functions

This creates functions subdirectory in your project's root which contains standard NodeJS package structure with package.json and index.js files.

2. Initialize Dart project #

Go to functions subfolder and add pubspec.yaml with following contents:

name: myproject_functions
description: My project functions
version: 0.0.1

  sdk: '>=1.20.1 <2.0.0'

  # Firebase Functions bindings
  firebase_functions_interop: ^0.0.1 
  # Node bindings required to compile a nice-looking JS file for Node.
  # Also provides access to globals like `require` and `exports`.
  node_interop: ^0.0.1 

  - $dart2js
  - node_interop # This transformer must go after $dart2js

Then run pub get to install dependencies.

3. Write a Web function #

Create bin/index.dart and type in something like this:

import 'package:firebase_functions_interop/firebase_functions_interop.dart';

void main() {
  FirebaseFunctions functions = new FirebaseFunctions();
  var httpsFunc = functions.https.onRequest((request, response) {
    response.send('Hello from Firebase Functions Dart Interop!');

  exports.setProperty('helloWorld', httpsFunc);

Copy-pasting also works.

4. Build your function #

Building functions is as simple as running pub build. Note that Pub by default assumes a "web" project and only builds web folder so we need to explicitely tell it about bin:

$ pub build bin

5. Copy and deploy #

The result of pub build is located in build/bin/index.dart.js. Replace default index.js with the built version:

$ cp build/bin/index.dart.js index.js

Deploy using Firebase CLI:

$ firebase deploy --only functions

6. Test it #

Navigate to the new function's URL printed out by the deploy command. You should see "Hello from Firebase Functions Dart Interop!" on the screen.
