React Query + Firestore

const { data } = useDocument('users/fernando')

It's that easy.

🔥 This library provides the hooks you need for querying Firestore, that you can actually use in production, on every screen.

⚡️ It aims to be the fastest way to use Firestore in a React app, both from a developer experience and app performance perspective.

🍕 This library is built on top react-query, meaning you get all of its awesome benefits out-of-the-box.

You can now fetch, add, and mutate Firestore data with zero boilerplate.


I'd like to thank (@fernandotherojo), this repo is a fork from his swr-firestore repo. all i did was migrating the core logic from swr to react query

make sure to check his repo:


  • Shared state / cache between collection and document queries (instead of Redux??)
  • Works with both React and React Native.
  • Blazing fast
  • Query collection groups
  • set, update, and add update your global cache, instantly
  • TypeScript-ready (see docs)
  • Realtime subscriptions (example)
  • Prevent memory leaks from Firestore subscriptions
  • No more parsing from Firestore requests

...along with the features touted by react-query library:

  • Transport and protocol agnostic data fetching
  • Fast page navigation
  • Revalidation on focus
  • Interval polling
  • Request deduplication
  • Local mutation
  • Pagination
  • TypeScript ready
  • SSR support
  • Suspense mode
  • Minimal API


If you like this library, give it star


yarn add react-query-firestore

# or
npm install react-query-firestore

Install firebase:

# if you're using expo:
expo install firebase

# if you aren't using expo:
yarn add firebase
# or
npm i firebase

Set up

In the root of your app, create an instance of firestore and (react query config object) and pass it to the ReactQueryFirestoreProvider.

If you're using next.js, this goes in your pages/_app.js file.


import React from 'react'
import * as firebase from 'firebase/app'
import 'firebase/firestore'
import { ReactQueryFirestoreProvider } from 'react-query-firestore'

const reactQueryConfig = {
  queries: {
    retry: false

export default function App() {
  return (
    <ReactQueryFirestoreProvider firestore={} reactQueryConfig={reactQueryConfig}>
      <YourAppHere />

Basic Usage

Assuming you've already completed the setup...

Subscribe to a document

import React from 'react'
import { useDocument } from 'react-query-firestore'
import { Text } from 'react-native'

export default function User() {
  const user = { id: 'Fernando' }
  const { data, update, error } = useDocument(`users/${}`)

  if (error) return <Text>Error!</Text>
  if (!data) return <Text>Loading...</Text>

  return <Text>Name: {}</Text>

Get a collection

import React from 'react'
import { useCollection } from 'react-query-firestore'
import { Text } from 'react-native'

export default function UserList() {
  const { data, add, error } = useCollection(`users`)

  if (error) return <Text>Error!</Text>
  if (!data) return <Text>Loading...</Text>

  return => <Text key={}>{}</Text>)

useDocument accepts a document path as its first argument here. useCollection works similarly.

Simple examples

Query a users collection:

const { data } = useCollection('users')

Make a complex collection query:

const { data } = useCollection('users', {}, {
  where: ['name', '==', 'fernando'],
  limit: 10,
  orderBy: ['age', 'desc'],

Pass options from react-query to your document query:

// pass react-query options
const { data } = useDocument('albums/nothing-was-the-same', {
  retry: false,
  onSuccess: console.log,

Pass options from react-query to your collection query:

// pass react-query options
const { data } = useCollection(
    retry: false,
    onSuccess: console.log,
    // you can pass multiple where conditions if you want
    where: [
      ['artist', '==', 'Drake'],
      ['year', '==', '2020'],

Add data to your collection:

const { data, add } = useCollection('albums', {
  where: ['artist', '==', 'Drake'],

const onPress = () => {
  // calling this will automatically update your global cache & Firestore
    title: 'Dark Lane Demo Tapes',
    artist: 'Drake',
    year: '2020',

Set document data:

const { data, set, update } = useDocument('albums/dark-lane-demo-tapes')

const onReleaseAlbum = () => {
  // calling this will automatically update your global cache & Firestore
      released: true,
    { merge: true }

  // or you could call this:
    released: true,

Use dynamic fields in a request:

If you pass undefined as the document key, the request won't send.

Once the key is set to a string, the request will send.

Get list of users who have you in their friends list

import { useDoormanUser } from 'react-doorman'

const { uid } = useDoormanUser()
const { data } = useDocument(uid ? 'users/'+uid : undefined, {
  where: ['friends', 'array-contains', uid],

Get your favorite song

const me = { id: 'fernando' }

const { data: user } = useDocument<{ favoriteSong: string }>(`users/${}`)

// only send the request once the user.favoriteSong exists!
const { data: song } = useDocument(
  user?.favoriteSong ? `songs/${user.favoriteSong}` : undefined

Query Documents

You'll rely on useDocument to query documents.

import React from 'react'
import { useDocument } from 'react-query-firestore'

const user = { id: 'Fernando' }
export default () => {
  const { data, error } = useDocument(`users/${}`)


TypeScript Support

Create a model for your typescript types, and pass it as a generic to useDocument or useCollection.


The data item will include your TypeScript model (or undefined), and will also include an id string, an exists boolean, and hasPendingWrites boolean.

type User = {
  name: string

const { data } = useDocument<User>('users/fernando')

if (data) {
  const {
    id, // string
    name, // string
    exists, // boolean
    hasPendingWrites, // boolean
  } = data

const id = data?.id //  string | undefined
const name = data?.name // string | undefined
const exists = data?.exists // boolean | undefined
const hasPendingWrites = data?.hasPendingWrites // boolean | undefined


The data item will include your TypeScript model (or undefined), and will also include an id string.

type User = {
  name: string

const { data } = useCollection<User>('users')

if (data) {
  data.forEach(({ id, name }) => {
    // ...

Shared global state between documents and collections

A great feature of this library is shared data between documents and collections. Until now, this could only be achieved with something like a verbose Redux set up.

So, what does this mean exactly?

Simply put, any documents pulled from a Firestore request will update the global cache.

To make it clear, let's look at an example.

Imagine you query a user document from Firestore:

const { data } = useDocument('users/fernando')

And pretend that this document's data returns the following:

{ "id": "fernando", "isHungry": false }

Remember that isHungry is false here ^

Now, let's say you query the users collection anywhere else in your app:

const { data } = useCollection('users')

And pretend that this collection's data returns the following:

  { "id": "fernando", "isHungry": true },

Whoa, isHungry is now true. But what happens to the original document query? Will we have stale data?

Answer: It will automatically re-render with the new data!

swr-firestore uses document id fields to sync any collection queries with existing document queries across your app.

That means that if you somehow fetch the same document twice, the latest version will update everywhere.
