Memanggil fungsi dari aplikasi

iOS+

Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Apple Anda.

Gunakan Swift Package Manager untuk menginstal dan mengelola dependensi Firebase.

1. Di Xcode, dengan project aplikasi Anda dalam keadaan terbuka, buka File > Add Packages.
2. Saat diminta, tambahkan repositori SDK platform Apple Firebase:

  https://github.com/firebase/firebase-ios-sdk

3. Pilih library Cloud Functions.
4. Setelah selesai, Xcode akan otomatis mulai me-resolve dan mendownload dependensi Anda di latar belakang.

Web version 9

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Web Anda. Pastikan untuk menjalankan perintah berikut dari terminal Anda:

   npm install firebase@9.10.0 --save
   

2. Wajibkan Firebase core dan Cloud Functions secara manual:

    import { initializeApp } from 'firebase/app';
    import { getFunctions } from 'firebase/functions';
   
    const app = initializeApp({
        projectId: '### CLOUD FUNCTIONS PROJECT ID ###',
        apiKey: '### FIREBASE API KEY ###',
        authDomain: '### FIREBASE AUTH DOMAIN ###',
      });
    const functions = getFunctions(app);
   

Web version 8

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Web Anda.
2. Tambahkan library klien Cloud Functions dan Firebase core ke aplikasi Anda:

   <script src="https://www.gstatic.com/firebasejs/8.10.1/firebase.js"></script>
   <script src="https://www.gstatic.com/firebasejs/8.10.1/firebase-functions.js"></script>
   

Cloud Functions SDK juga tersedia sebagai paket npm.

1. Jalankan perintah berikut dari terminal Anda:

   npm install firebase@8.10.1 --save
   

2. Wajibkan Firebase core dan Cloud Functions secara manual:

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

Java

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Android Anda.

2. Dalam file Gradle modul (level aplikasi), (biasanya <project>/<app-module>/build.gradle), tambahkan dependensi untuk library Android Cloud Functions. Sebaiknya gunakan Firebase Android BoM untuk mengontrol pembuatan versi library.

   dependencies {
       // Import the BoM for the Firebase platform
       implementation platform('com.google.firebase:firebase-bom:30.4.1')
   
       // Add the dependency for the Cloud Functions library
       // When using the BoM, you don't specify versions in Firebase library dependencies
       implementation 'com.google.firebase:firebase-functions'
   }
   

   Dengan menggunakan Firebase Android BoM, aplikasi Anda akan selalu menggunakan versi library Android Firebase yang kompatibel.

   (Alternatif) Tambahkan dependensi library Firebase tanpa menggunakan BoM

   Jika memilih untuk tidak menggunakan Firebase BoM, Anda harus menentukan setiap versi library Firebase di baris dependensinya.

   Perlu diperhatikan bahwa jika Anda menggunakan beberapa library Firebase di aplikasi, sebaiknya gunakan BoM untuk mengelola versi library, yang memastikan bahwa semua versi kompatibel.

   dependencies {
       // Add the dependency for the Cloud Functions library
       // When NOT using the BoM, you must specify versions in Firebase library dependencies
       implementation 'com.google.firebase:firebase-functions:20.1.1'
   }

Dart

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Flutter Anda.

2. Dari root project Flutter Anda, jalankan perintah berikut untuk menginstal plugin:

   flutter pub add cloud_functions
   

3. Setelah selesai, build ulang aplikasi Flutter Anda:

   flutter run
   

4. Setelah diinstal, Anda dapat mengakses plugin cloud_functions dengan mengimpornya di kode Dart:

   import 'package:cloud_functions/cloud_functions.dart';
   

C++

Untuk C++ dengan Android:

1. Ikuti petunjuk untuk menambahkan Firebase ke project C++ Anda.
2. Tambahkan library firebase_functions ke file CMakeLists.txt Anda.

Untuk C++ dengan platform Apple:

1. Ikuti petunjuk untuk menambahkan Firebase ke project C++ Anda.
2. Tambahkan pod Cloud Functions ke Podfile:

   pod 'Firebase/Functions'

3. Simpan file, lalu jalankan:

   pod install

4. Tambahkan framework Cloud Functions dan Firebase core dari Firebase C++ SDK ke project Xcode Anda.
   • firebase.framework
   • firebase_functions.framework

Unity

1. Ikuti petunjuk untuk menambahkan Firebase ke project Unity Anda.
2. Tambahkan FirebaseFunctions.unitypackage dari Firebase Unity SDK ke project Unity Anda.
