ES 2017 transpilation

This sample shows how you can write your Cloud Functions code using the ES2017 syntax - which is not supported natively by Cloud Functions. This requires to run a preparation step where your code is transpiled to a supported version of JavaScript.

Functions Code

See file functions/index.es7 for the code.

The function is a simple hello world sample that will write "Hello " as the value of any node created as /hello/<name> in the Firebase Realtime Database.

We're using some ES2017 syntax that is not supported natively by Cloud Functions such as async/await. The code will be transpiled to ES5 using the BabelJS CLI.

See the functions/package.json file for the prepare script which runs the transpilation step.

Deploy and test

This sample comes with a Function and web-based UI for testing the function. To configure it:

  1. Create a Firebase Project using the Firebase Console.
  2. Clone or download this repo and open the es2017-transpile directory.
  3. You must have the Firebase CLI installed. If you don't have it install it with npm install -g firebase-tools and then configure it with firebase login.
  4. Configure the CLI locally by using firebase use --add and select your project in the list.
  5. Install dependencies locally by running: cd functions; npm install; cd -
  6. Transpile the code bu running: cd functions; npm run prepare; cd -
  7. Deploy your project using firebase deploy
  8. Open the Firebase console for your project and using the Realtime Database tab, create a node /hello/Bob with value true. Soon after the node has been created the Function will change the value to Hello Bob
