Chiama le funzioni dalla tua app

iOS

1. Segui le istruzioni per aggiungere Firebase alla tua app iOS .
2. Aggiungi il pod Cloud Functions al tuo Podfile :

   pod 'Firebase/Functions'

3. Salva il file, quindi esegui:

   pod install

ragnatela

1. Segui le istruzioni per aggiungere Firebase alla tua app web .
2. Aggiungi le librerie client Firebase core e Cloud Functions alla tua app:

   <script src="https://www.gstatic.com/firebasejs/7.21.0/firebase.js"></script>
   <script src="https://www.gstatic.com/firebasejs/7.21.0/firebase-functions.js"></script>
   

L'SDK di Cloud Functions è disponibile anche come pacchetto npm.

1. Esegui il seguente comando dal tuo terminale:

   npm install firebase@7.21.0 --save
   

2. Richiede manualmente sia Firebase core che Cloud Functions:

   const firebase = require("firebase");
   // Required for side-effects
   require("firebase/functions");
   

Giava

1. Segui le istruzioni per aggiungere Firebase alla tua app Android .
2. Nel tuo file build.gradle livello di build.gradle , assicurati di includere il repository Maven di Google in entrambe le sezioni buildscript e allprojects .
3. Aggiungi la dipendenza per la libreria Android di Cloud Functions al file Gradle del modulo (a livello di app) (solitamente app/build.gradle ):

   implementation 'com.google.firebase:firebase-functions:19.1.0'
