NPM version Build Status codecov MIT licensed code style: prettier Release Notes Donate

Use Google Firestore in React with zero effort, using MobX 🤘

  • 🎶 Simple, easy to use API, get up & running in minutes
  • 🚀 Fast, only fetches and re-renders data when needed
  • 🤘 No clutter, no complex stores/providers/actions/reducers, just go

The latest version is compatible with the Firebase v9 API.

yarn add firestorter

1. Initialize

import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';
import { initFirestorter } from 'firestorter';
import makeWebContext from 'firestorter/web';

// Initialize firebase app
const app = initializeApp({ ... });
const firestore = getFirestore(app);

// Initialize `firestorter`
initFirestorter(makeWebContext({ firestore }));

See here on how to use with react-native, compat mode and older firebase SDKs.

2. Create a Collection or Document

import { Collection, Document } from 'firestorter';

const todos = new Collection('todos');
const user = new Document('users/8273872***');

3. Wrap your Components with mobx's observer pattern

import * as React from 'react';
import { observer } from 'mobx-react';

const Todos = observer(() => {
  return <div>
    {todos.docs.map((doc) => (
      <TodoItem
        key={doc.id}
        doc={doc} />
    ))}
  </div>;
});

const TodoItem = observer(({doc}) => {
  const { finished, text } = doc.data;
  return <div>
    <input type='checkbox' checked={finished} />
    <input type='text' value={text} />
  </div>;
});

That's it. Your Components will now render your firestore data and re-render when data in the back-end changes.

How it works

Firestorter makes integrating Firestore real-time data into React easy as pie. It does this by providing a simple API for accessing Collection and Document data, whilst taking away the burden of managing snapshot listeners, data-caching and efficiently updating your React components.

It does this by intelligently tracking whether a Collection or Document should be listening for real-time updates (onSnapshot events) or not. Whenever a Component renders a Collection or Document, firestorter enables real-time updates on that resource. And whenever a Component stops using the resource (e.g., component was unmounted), it stops listening for snapshot updates. This behavior really shines when multiple components are rendering collection/document data and it becomes more difficult to determine whether snapshot updates should be enabled or not.
