firebase-functions-mock

Work locally with firebase functions

Install

npm install firebase-functions-mock

Supports

• onRequest express app handling
• onWrite database event handling
• Mocks out auth and config
• Runs static delivery of your public files folder

How to use

functions/index.js

const firebase = require('firebase-admin');
const admin = firebase.initializeApp({
  credential: firebase.credential.cert(JSON.parse(process.env.SERVICE_ACCOUNT)),
  databaseURL: JSON.parse(process.env.FIREBASE_CONFIG).databaseURL,
});
let functions = require('firebase-functions');

// When in debug mode, override functions with the mock and
// pass in the instance of "admin" and optional options
if (process.env.NODE_ENV !== 'production') {
  functions = require('firebase-functions-mock')(admin, {
    config: process.env.FIREBASE_CONFIG,
    port: 3001,
    publicPath: 'public'
  });
}

exports.app = functions.https.onRequest(require('./app'));
exports.publish = functions.database.ref('articles/{uid}/{articleName}').onWrite(require('./publish'));

Limitations

This project is in its initial state to build the jsblog.io project. It has a lot of potential for improvements. Although contributions are already made, here are some things to look into:

• Test more scenarios with onWrite usage

Get going

To get going with Firebase Functions I highly recommend using this boilerplate which has the whole workflow set up for you.
