This quickstart shows you how to set up Cloud Firestore, add data, then use either Core operations or Pipeline operations to query the data you just added in the Firebase console using server client libraries for Java, Node.js, and Python.
Use these client libraries to set up privileged server environments with full access to your database..
Create a Cloud Firestore database
If you haven't already, create a Firebase project: In the Firebase console, click Add project, then follow the on-screen instructions to create a Firebase project or to add Firebase services to an existing Google Cloud project.
Open your project in the Firebase console. In the left panel, expand Build and then select Firestore database.
Click Create database.
Select Enterprise for the database mode.
Select Firestore in Native Mode for the operation mode, which supports Core and Pipeline operations.
Select a location for your database.
Select a starting mode for your Cloud Firestore Security Rules:
- Test mode
Good for getting started with the mobile and web client libraries, but allows anyone to read and overwrite your data. After testing, make sure to review the Secure your data section.
To get started with the web, Apple platforms, or Android SDK, select test mode.
- Production mode
Denies all reads and writes from mobile and web clients. Your authenticated application servers (Node.js, Python, Java) can still access your database.
Your initial set of Cloud Firestore Security Rules will apply to your default Cloud Firestore database. If you create multiple databases for your project, you can deploy Cloud Firestore Security Rules for each database.
Click Create.
When you enable Cloud Firestore, it also enables the API in the Cloud API Manager.
Set up your development environment
Add the required dependencies and client libraries to your app.
Node.js
-
Add the Firebase Admin SDK to your app:
npm install firebase-admin --save
- Follow the instructions below to initialize Cloud Firestore with the proper credentials in your environment.
Python
- Add the Firebase Admin SDK to your Python app:
pip install --upgrade firebase-admin
- Follow the instructions below to initialize Cloud Firestore with the proper credentials in your environment.
Java
- Add the Firebase Admin SDK to your app:
-
Using Gradle:
implementation 'com.google.firebase:firebase-admin:9.7.0'
-
Using Maven:
<dependency> <groupId>com.google.firebase</groupId> <artifactId>firebase-admin</artifactId> <version>9.7.0</version> </dependency>
-
Using Gradle:
- Follow the instructions below to initialize Cloud Firestore with the proper credentials in your environment.
Initialize Cloud Firestore
Initialize an instance of Cloud Firestore:
Node.js
The Cloud Firestore SDK is initialized in different ways depending on your environment. Below are the most common methods. For a complete reference, see Initialize the Admin SDK.-
Initialize on Cloud Functions
const { initializeApp, applicationDefault, cert } = require('firebase-admin/app'); const { getFirestore, Timestamp, FieldValue, Filter } = require('firebase-admin/firestore');
initializeApp(); const db = getFirestore();
-
Initialize on Google Cloud
const { initializeApp, applicationDefault, cert } = require('firebase-admin/app'); const { getFirestore, Timestamp, FieldValue, Filter } = require('firebase-admin/firestore');
initializeApp({ credential: applicationDefault() }); const db = getFirestore();
-
Initialize on your own server
To use the Firebase Admin SDK on your own server (or any other Node.js environment), use a service account. Go to IAM & admin > Service accounts in the Google Cloud console. Generate a new private key and save the JSON file. Then use the file to initialize the SDK:
const { initializeApp, applicationDefault, cert } = require('firebase-admin/app'); const { getFirestore, Timestamp, FieldValue, Filter } = require('firebase-admin/firestore');
const serviceAccount = require('./path/to/serviceAccountKey.json'); initializeApp({ credential: cert(serviceAccount) }); const db = getFirestore();
Python
The Cloud Firestore SDK is initialized in different ways depending on your environment. Below are the most common methods. For a complete reference, see Initialize the Admin SDK.import firebase_admin from firebase_admin import firestore # Application Default credentials are automatically created. app = firebase_admin.initialize_app() db = firestore.client()
An existing application default credential can also be used to initialize the SDK.
import firebase_admin from firebase_admin import credentials from firebase_admin import firestore # Use the application default credentials. cred = credentials.ApplicationDefault() firebase_admin.initialize_app(cred) db = firestore.client()
To use the Firebase Admin SDK on your own server, use a service account.
Go to IAM & admin > Service accounts in the Google Cloud console. Generate a new private key and save the JSON file. Then use the file to initialize the SDK:
import firebase_admin from firebase_admin import credentials from firebase_admin import firestore # Use a service account. cred = credentials.Certificate('path/to/serviceAccount.json') app = firebase_admin.initialize_app(cred) db = firestore.client()
Java
The Cloud Firestore SDK is initialized in different ways depending on your environment. Below are the most common methods. For a complete reference, see Initialize the Admin SDK.import com.google.auth.oauth2.GoogleCredentials; import com.google.cloud.firestore.Firestore; import com.google.firebase.FirebaseApp; import com.google.firebase.FirebaseOptions; // Use the application default credentials GoogleCredentials credentials = GoogleCredentials.getApplicationDefault(); FirebaseOptions options = new FirebaseOptions.Builder() .setCredentials(credentials) .setProjectId(projectId) .build(); FirebaseApp.initializeApp(options); Firestore db = FirestoreClient.getFirestore();
To use the Firebase Admin SDK on your own server, use a service account.
Go to IAM & admin > Service accounts in the Google Cloud console. Generate a new private key and save the JSON file. Then use the file to initialize the SDK:
import com.google.auth.oauth2.GoogleCredentials; import com.google.cloud.firestore.Firestore; import com.google.firebase.FirebaseApp; import com.google.firebase.FirebaseOptions; // Use a service account InputStream serviceAccount = new FileInputStream("path/to/serviceAccount.json"); GoogleCredentials credentials = GoogleCredentials.fromStream(serviceAccount); FirebaseOptions options = new FirebaseOptions.Builder() .setCredentials(credentials) .build(); FirebaseApp.initializeApp(options); Firestore db = FirestoreClient.getFirestore();
Add data using Core operations
In order to explore Core operations and Pipeline operations for querying data, add data to your database using Core operations.
Cloud Firestore stores data in Documents, which are stored in Collections. Cloud Firestore creates collections and documents implicitly the first time you add data to the document. You don't need to explicitly create collections or documents.
Create a new collection and a document using the following example code.
Node.js
Java
Python
Read data using Core operations
Use the data viewer in the Firebase console to quickly verify that you've added data to Cloud Firestore.
You can also use the "get" method to retrieve the entire collection.
Node.js
Python
users_ref = db.collection("users") docs = users_ref.stream() for doc in docs: print(f"{doc.id} => {doc.to_dict()}")
Java
Read data using Pipeline operations
Now you can compare the Pipeline query experience with the Core query experience.
Node.js
const readDataPipeline = db.pipeline() .collection("users"); // Execute the pipeline and handle the result try { const querySnapshot = await readDataPipeline.execute(); querySnapshot.results.forEach((result) => { console.log(`${result.id} => ${result.data()}`); }); } catch (error) { console.error("Error getting documents: ", error); }
Python
pipeline = client.pipeline().collection("users") for result in pipeline.execute(): print(f"{result.id} => {result.data()}")
Java
Pipeline pipeline = firestore.pipeline().collection("users"); ApiFuture<Pipeline.Snapshot> future = pipeline.execute(); for (com.google.cloud.firestore.PipelineResult result : future.get().getResults()) { System.out.println(result.getId() + " => " + result.getData()); } // or, asynchronously pipeline.execute( new ApiStreamObserver<com.google.cloud.firestore.PipelineResult>() { @Override public void onNext(com.google.cloud.firestore.PipelineResult result) { System.out.println(result.getId() + " => " + result.getData()); } @Override public void onError(Throwable t) { System.err.println(t); } @Override public void onCompleted() { System.out.println("done"); } });
