اتّبِع التعليمات لإضافة Firebase إلى تطبيقك على Apple.

استخدِم أداة Swift Package Manager لتثبيت تبعيات Firebase وإدارتها.

1. في Xcode، مع فتح مشروع تطبيقك، انتقِل إلى ملف > إضافة حِزم.
2. أضِف مستودع حزمة تطوير البرامج (SDK) لمنصّات Apple من Firebase عندما يُطلب منك ذلك:

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

3. اختَر مكتبة Cloud Functions.
4. أضِف العلامة -ObjC إلى قسم رموز ربط أخرى في إعدادات الإنشاء الخاصة بالهدف.
5. عند الانتهاء، سيبدأ Xcode تلقائيًا في حلّ ملفاتك المضمّنة وتنزيلها في الخلفية.

Web

1. اتّبِع التعليمات لإضافة Firebase إلى تطبيق الويب. احرص على تنفيذ الأمر التالي من وحدة التحكّم الطرفية:

   npm install firebase@11.0.2 --save
   

2. يمكنك طلب Firebase Core وCloud Functions يدويًا:

    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);
   

Android

1. اتّبِع التعليمات لإضافة Firebase إلى تطبيق Android.

2. في ملف Gradle للوحدة (على مستوى التطبيق) (عادةً <project>/<app-module>/build.gradle.kts أو <project>/<app-module>/build.gradle)، أضِف الاعتمادية لمكتبة Cloud Functions لنظام التشغيل Android. ننصحك باستخدام الرمز Firebase Android BoM للتحكّم في إصدارات المكتبة.

   dependencies {
       // Import the BoM for the Firebase platform
       implementation(platform("com.google.firebase:firebase-bom:33.6.0"))
   
       // 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")
   }
   

   باستخدام Firebase Android BoM، سيستخدم تطبيقك دائمًا إصدارات متوافقة من مكتبات Firebase لنظام التشغيل Android.

   (بديل)  إضافة تبعيات مكتبة Firebase بدون استخدام BoM

   إذا اخترت عدم استخدام Firebase BoM، يجب تحديد كل إصدار من مكتبة Firebase في سطر التبعية الخاص به.

   يُرجى العلم أنّه في حال استخدام مكتبات Firebase متعدّدة في تطبيقك، ننصحك بشدة باستخدام BoM لإدارة إصدارات المكتبة، ما يضمن توافق جميع الإصدارات.

   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:21.1.0")
   }
   

   هل تبحث عن وحدة مكتبة خاصة بلغة Kotlin؟ اعتبارًا من تشرين الأول (أكتوبر) 2023 (Firebase BoM 32.5.0)، يمكن لمطوّري Kotlin وJava الاعتماد على وحدة المكتبة الرئيسية (للاطّلاع على التفاصيل، راجِع الأسئلة الشائعة حول هذه المبادرة).
