Organize Cloud Functions for Firebase

Question

What is the best practice to organize all our Cloud Functions for Firebase?

I see from the sample GitHub repository that all functions reside in a single index

Answer 1

You could use something like export { functionName } from './file' at your index.js file.

/functions/index.js

// This is the main entry point for the app written in ES that is compatible with node lts
import * as functions from 'firebase-functions';

export { sendWelcomeEmail } from './userEmails';

exports.helloWorld = functions.https.onRequest((request, response) => {
  let helloMsg = `Hello!`;
  response.send(helloMsg);
});
