Menambahkan Firebase Admin SDK ke server

Node.js

Firebase Admin Node.js SDK tersedia di npm. Jika Anda belum memiliki file package.json, buat file tersebut melalui npm init. Selanjutnya, instal paket npm firebase-admin dan simpan ke package.json Anda:

npm install firebase-admin --save

Untuk menggunakan modul tersebut di aplikasi Anda, terapkan require padanya dari file JavaScript apa pun:

const { initializeApp } = require('firebase-admin/app');

Jika menggunakan ES2015, Anda dapat menerapkan import pada modul tersebut:

import { initializeApp } from 'firebase-admin/app';

Java

Firebase Admin Java SDK dipublikasikan ke repositori pusat Maven. Untuk menginstal library tersebut, deklarasikan sebagai dependensi di file build.gradle Anda:

dependencies {
  implementation 'com.google.firebase:firebase-admin:9.4.1'
}

Jika menggunakan Maven untuk mem-build aplikasi, Anda dapat menambahkan dependensi berikut ke pom.xml:

<dependency>
  <groupId>com.google.firebase</groupId>
  <artifactId>firebase-admin</artifactId>
  <version>9.4.1</version>
</dependency>

Python

Firebase Admin Python SDK tersedia melalui pip. Anda dapat menginstal library tersebut untuk semua pengguna melalui sudo:

sudo pip install firebase-admin

Atau, Anda dapat menginstal library hanya untuk pengguna saat ini dengan meneruskan flag --user:

pip install --user firebase-admin

Go

Go Admin SDK dapat diinstal menggunakan utilitas go get:

# Install the latest version:
go get firebase.google.com/go/v4@latest

# Or install a specific version:
go get firebase.google.com/go/[email protected]

C#

Admin SDK .NET dapat diinstal menggunakan pengelola paket .NET:

Install-Package FirebaseAdmin -Version 3.1.0

Sebagai alternatif, Anda dapat menginstalnya menggunakan aplikasi utilitas command line dotnet:

dotnet add package FirebaseAdmin --version 3.1.0

Atau, Anda dapat menginstalnya dengan menambahkan entri referensi paket berikut ke file .csproj Anda:

<ItemGroup>
  <PackageReference Include="FirebaseAdmin" Version="3.1.0" />
</ItemGroup>

Node.js

const app = initializeApp();

Java

FirebaseApp.initializeApp();

C#

FirebaseApp.Create();

Node.js

const myRefreshToken = '...'; // Get refresh token from OAuth2 flow

initializeApp({
  credential: refreshToken(myRefreshToken),
