अपने सर्वर पर Firebase एडमिन SDK टूल जोड़ना

Node.js

Firebase Admin Node.js SDK टूल, npm पर उपलब्ध है. अगर आपके पास पहले से कोई package.json फ़ाइल नहीं है, तो npm init की मदद से एक फ़ाइल बनाएं. इसके बाद, firebase-admin npm पैकेज इंस्टॉल करें और उसे अपने package.json में सेव करें:

npm install firebase-admin --save

अपने ऐप्लिकेशन में मॉड्यूल का इस्तेमाल करने के लिए, किसी भी JavaScript फ़ाइल से require इसे इंपोर्ट करें:

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

अगर ES2015 का इस्तेमाल किया जा रहा है, तो मॉड्यूल को import किया जा सकता है:

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

Java

Firebase Admin Java SDK टूल, Maven Central डेटा स्टोर में पब्लिश किया गया है. लाइब्रेरी इंस्टॉल करने के लिए, अपनी build.gradle फ़ाइल में इसे डिपेंडेंसी के तौर पर शामिल करें:

dependencies {
  implementation 'com.google.firebase:firebase-admin:9.4.2'
}

अगर आपने अपने ऐप्लिकेशन को बनाने के लिए Maven का इस्तेमाल किया है, तो अपने pom.xml में यह डिपेंडेंसी जोड़ें:

<dependency>
  <groupId>com.google.firebase</groupId>
  <artifactId>firebase-admin</artifactId>
  <version>9.4.2</version>
</dependency>

Python

Firebase Admin Python SDK, pip के ज़रिए उपलब्ध है. sudo ���� मदद से, सभी उपयोगकर्ताओं के लिए लाइब्रेरी इंस्टॉल की जा सकती है:

sudo pip install firebase-admin

इसके अलावा, --user फ़्लैग का इस्तेमाल करके, लाइब्रेरी को सिर्फ़ मौजूदा उपयोगकर्ता के ल���ए इंस्टॉल किया जा सकता है:

pip install --user firebase-admin

शुरू करें

Go Admin SDK को go get यूटिलिटी का इस्तेमाल करके इंस्टॉल किया जा सकता है:

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

# Or install a specific version:
go get firebase.google.com/go/v4@4.15.1

C#

.NET Admin SDK को .NET पैकेज मैनेजर का इस्तेमाल करके इंस्टॉल किया जा सकता है:

Install-Package FirebaseAdmin -Version 3.1.0

इसके अलावा, dotnet कमांड-लाइन यूटिलिटी का इस्तेमाल करके इसे इंस्टॉल करें:

dotnet add package FirebaseAdmin --version 3.1.0

इसके अलावा, अपनी .csproj फ़ाइल में पैकेज की यह रेफ़रंस एंट्री जोड़कर भी इसे इंस्टॉल किया जा सकता है:

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