ReactFire

Hooks, Context Providers, and Components that make it easy to interact with Firebase.

⚠️ Status: Experimental. The API is intended to be stable, but ReactFire is meant for React Concurrent Mode, which is only available in experimental React builds.

What is ReactFire?

• Easy realtime updates for your function components - Hooks like useUserand useFirestoreCollection let you easily subscribe to auth state, realtime data, and all other Firebase SDK events. Plus, they automatically unsubscribe when your component unmounts.
• Loading states handled by <Suspense> - ReactFire's hooks throw promises that Suspense can catch. No more isLoaded ?... - let React handle it for you.
• Faster initial page load times - Load only the code you need, when you need it, with useFirestore, useAuth, useRemoteConfig, and more.
• Convenient components for common use cases - Only want to render a component if a user is signed in? Wrap it in <AuthCheck />. Need to automatically instrument your Suspense load times with RUM? Use <SuspenseWithPef />.

import React, { Component } from 'react';
import { createRoot } from 'react-dom';
import {
  FirebaseAppProvider,
  useFirestoreDocData,
  useFirestore,
  SuspenseWithPerf
} from 'reactfire';

const firebaseConfig = {
  /* Add your config from the Firebase Console */
};

function Burrito() {
  // lazy load the Firestore SDK
  // and create a ref
  const burritoRef = useFirestore()
    .collection('tryreactfire')
    .doc('burrito');

  // subscribe to the doc. just one line!
  // throws a Promise for Suspense to catch,
  // and then streams live updates
  const burrito = useFirestoreDocData(burritoRef);

  return <p>The burrito is {burrito.yummy ? 'good' : 'bad'}!</p>;
}

function App() {
  return (
    <FirebaseAppProvider firebaseConfig={firebaseConfig}>
      <h1>🌯</h1>
      <SuspenseWithPerf
        fallback={<p>loading burrito status...</p>}
        traceId={'load-burrito-status'}
      >
        <Burrito />
      </SuspenseWithPerf>
    </FirebaseAppProvider>
  );
}

// Enable Concurrent Mode
