Firebase Functions Quickstart

Introduction

This quickstart demonstrates Callable Functions which are HTTPS Cloud Functions that can be invoked directly from your mobile application.

Getting Started

• Add Firebase to your iOS Project.
• Set up Firebase Functions Functions in the docs should be updated, since the functions applied in the quickstart might not be the same as the ones in the example from the doc above.

To align with the quickstart, the index.js should be updated to

const functions = require('firebase-functions');

exports.addNumbers = functions.https.onRequest((request, response) => {
  var first = Number(request.body.data.firstNumber);
  var second = Number(request.body.data.secondNumber);
  response.json({ data: {operationResult: first + second} });
});

exports.capitalizeMessage = functions.https.onRequest((request, response) => {
  var upText = request.body.data.text;
  response.json({ data: {text: upText.toUpperCase()} });
});

• Run on a local machine To let the quickstart run on a local machine, you can Emulate execution of your functions locally by adding a flag -D EMULATOR to the Other Swift Flags under the Build Settings.

• Run in production Once functions are deployed to a production environment, the Functions quickstart can just build and run without additional settings to connect to a Firebase project. Remember to remove the -D EMULATOR flag if you ran the quickstart through an emulator before.
