Reactfire

• Easy realtime updates for your function components - Reactfire's hooks, like useFirestoreCollection and useUser, let you easily subscribe to events, and 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.
• Dead-simple Real User Monitoring (RUM) - Easily enable Firebase Performance Monitoring's automatic traces, and instrument your Suspenseful loads with Reactfire's <SuspenseWithPerf> component

# npm
npm install --save reactfire

# yarn
yarn add reactfire
