Memulai Cloud Firestore

Web v8

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

   <script src="https://www.gstatic.com/firebasejs/8.7.1/firebase-app.js"></script>
   <script src="https://www.gstatic.com/firebasejs/8.7.1/firebase-firestore.js"></script>

   Cloud Firestore SDK juga tersedia sebagai paket npm.

   npm install firebase@8.7.1 --save
   

   Anda harus mewajibkan Firebase dan Cloud Firestore secara manual.

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

Web v9

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Web Anda.
2. Cloud Firestore SDK tersedia sebagai paket npm.

   npm install firebase@9.0.0-beta.6 --save
   

   Anda harus mengimpor Firebase dan Cloud Firestore.

   import { initializeApp } from "firebase/app";
   import { getFirestore } from "firebase/firestore";
   

iOS

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi iOS Anda.
2. Tambahkan pod Cloud Firestore ke Podfile Anda

   pod 'Firebase/Firestore'
   
   # Optionally, include the Swift extensions if you're using Swift.
   pod 'FirebaseFirestoreSwift'
   

3. Simpan file dan jalankan pod install.

Java

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Android Anda.
2. Dengan Firebase Android BoM, deklarasikan dependensi untuk library Android Cloud Firestore dalam file Gradle modul (level aplikasi), biasanya app/build.gradle.

   dependencies {
       // Import the BoM for the Firebase platform
       implementation platform('com.google.firebase:firebase-bom:28.2.1')
   
       // Declare the dependency for the Cloud Firestore library
       // When using the BoM, you don't specify versions in Firebase library dependencies
       implementation 'com.google.firebase:firebase-firestore'
   }
   

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

   (Alternatif) Deklarasikan dependensi library Firebase tanpa menggunakan BoM

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

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

   dependencies {
       // Declare the dependency for the Cloud Firestore library
       // When NOT using the BoM, you must specify versions in Firebase library dependencies
       implementation 'com.google.firebase:firebase-firestore:23.0.2'
   }
   

Kotlin+KTX

1. Ikuti petunjuk untuk menambahkan Firebase ke aplikasi Android Anda.
2. Dengan Firebase Android BoM, deklarasikan dependensi untuk library Android Cloud Firestore dalam file Gradle modul (level aplikasi), biasanya app/build.gradle.

   dependencies {
       // Import the BoM for the Firebase platform
       implementation platform('com.google.firebase:firebase-bom:28.2.1')
   
       // Declare the dependency for the Cloud Firestore library
       // When using the BoM, you don't specify versions in Firebase library dependencies
       implementation 'com.google.firebase:firebase-firestore-ktx'
   }

            arguments "-DFIREBASE_CPP_SDK_DIR=$gradle.firebase_cpp_sdk_dir"
          }
  
          apply from: "$gradle.firebase_cpp_sdk_dir/Android/firebase_dependencies.gradle"
          firebaseCpp.dependencies {
            // earlier entries
            auth
            firestore
          }
          

• Dependensi biner. Demikian pula, cara yang direkomendasikan untuk mendapatkan dependensi biner adalah dengan menambahkan kode berikut ke file CMakeLists.txt Anda:

          add_subdirectory(${FIREBASE_CPP_SDK_DIR} bin/ EXCLUDE_FROM_ALL)
          set(firebase_libs firebase_auth firebase_firestore firebase_app)
          # Replace the target name below with the actual name of your target,
          # for example, "native-lib".
          target_link_libraries(${YOUR_TARGET_NAME_HERE} "${firebase_libs}")

PHP

1. Library klien server Cloud Firestore (Java, Node.js, Python, Go, PHP, C#, dan Ruby) menggunakan Kredensial Default Aplikasi Google untuk melakukan autentikasi.
   • Untuk mengautentikasi dari lingkungan pengembangan, atur agar variabel lingkungan GOOGLE_APPLICATION_CREDENTIALS mengarah ke file kunci akun layanan JSON. Anda dapat membuat file kunci di halaman Kredensial Konsol API.

     export GOOGLE_APPLICATION_CREDENTIALS="path/to/your/keyfile.json"

   • Anda tidak perlu melakukan autentikasi jika menjalankan aplikasi pada App Engine atau Compute Engine di lingkungan produksi, menggunakan project yang sama dengan yang digunakan untuk Cloud Firestore. Jika menggunakan project berbeda, siapkan akun layanan.
2. Instal dan aktifkan ekstensi gRPC untuk PHP, yang akan Anda perlukan untuk menggunakan library klien.
3. Tambahkan library PHP Cloud Firestore ke aplikasi Anda:

   composer require google/cloud-firestore
