Firebase Tools: Powering Your Development Workflow

Firebase Tools provides a comprehensive suite of tools and APIs to enhance your development experience. Whether you’re managing a complex application or just starting out, Firebase Tools has the capabilities to streamline your process. Here, we delve into its key APIs with plenty of examples to get you rolling.

Introduction to Firebase Tools

Firebase Tools is a command-line interface that allows you to manage and deploy Firebase projects. With the power of Firebase CLI, developers can quickly integrate Firebase services into their applications, manage resources, and ensure smooth deployments.

API Examples

Initialization

First, initialize your Firebase project.

  
    firebase init
  

Authentication API

Manage authentication, users, and roles easily.

  
    // Sign up a new user
    firebase.auth().createUserWithEmailAndPassword(email, password)
      .then(userCredential => {
        // User signed up
      })
      .catch(error => {
        console.error(error);
      });

    // Sign in an existing user
    firebase.auth().signInWithEmailAndPassword(email, password)
      .then(userCredential => {
        // User signed in
      })
      .catch(error => {
        console.error(error);
      });

    // Sign out user
    firebase.auth().signOut()
      .then(() => {
        // User signed out
      })
      .catch(error => {
        console.error(error);
      });
  

Firestore API

Firestore is a flexible, scalable database for mobile, web, and server development.

  
    // Add a new document
    firebase.firestore().collection('users').add({
      first: 'Ada',
      last: 'Lovelace',
      born: 1815
    })
    .then(docRef => {
      console.log('Document written with ID: ', docRef.id);
    })
    .catch(error => {
      console.error('Error adding document: ', error);
    });

    // Get a document
    firebase.firestore().collection('users').doc(docRef.id).get()
      .then(doc => {
        if (doc.exists) {
          console.log('Document data:', doc.data());
        } else {
          // doc.data() returns undefined
          console.log('No such document!');
        }
      })
      .catch(error => {
        console.log('Error getting document:', error);
      });

    // Update a document
    firebase.firestore().collection('users').doc(docRef.id).update({
      last: 'Byron'
    })
    .then(() => {
      console.log('Document successfully updated!');
    })
    .catch(error => {
      // The document probably doesn't exist.
      console.error('Error updating document: ', error);
    });

    // Delete a document
    firebase.firestore().collection('users').doc(docRef.id).delete()
    .then(() => {
      console.log('Document successfully deleted!');
    })
    .catch(error => {
      console.error('Error removing document: ', error);
    });
  

Cloud Functions

Run backend code in response to events triggered by Firebase features and HTTPS requests.

  
    const functions = require('firebase-functions');

    // Create and Deploy Your First Cloud Functions
    // https://firebase.google.com/docs/functions/write-firebase-functions

    exports.helloWorld = functions.https.onRequest((request, response) => {
      response.send("Hello from Firebase!");
    });

    // Deploy the function
    firebase deploy --only functions
  

Complete Example Application

Here is a complete example of a simple web application using the Firebase SDKs for authentication and Firestore.
