Redux bindings for Firestore. Provides low-level API used in other libraries such as react-redux-firebase
npm install redux-firestore --save
This assumes you are using npm as your package manager.
If you're not, you can access the library on unpkg, download it, or point your package manager to it. Theres more on this in the Builds section below
Most likely, you'll want react bindings, for that you will need react-redux-firebase. You can install the current version it by running:
npm install --save react-redux-firebase
react-redux-firebase provides withFirestore
and firestoreConnect
higher order components, which handle automatically calling redux-firestore
internally based on component's lifecycle (i.e. mounting/un-mounting)
import { createStore, combineReducers, compose } from 'redux'
import { reduxFirestore, firestoreReducer } from 'redux-firestore'
import firebase from 'firebase'
import 'firebase/firestore'
const firebaseConfig = {} // from Firebase Console
// Initialize firebase instance
firebase.initializeApp(firebaseConfig)
// Initialize Cloud Firestore through Firebase
firebase.firestore();
// Add reduxFirestore store enhancer to store creator
const createStoreWithFirebase = compose(
reduxFirestore(firebase), // firebase instance as first argument
)(createStore)
// Add Firebase to reducers
const rootReducer = combineReducers({
firestore: firestoreReducer
})
// Create store with reducers and initial state
const initialState = {}
const store = createStoreWithFirebase(rootReducer, initialState)
Then pass store to your component's context using react-redux's Provider
:
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
render(
<Provider store={store}>
<MyRootComponent />
</Provider>,
rootEl
)
It is common to make react components "functional" meaning that the component is just a function instead of being a class
which extends React.Component
. This can be useful, but then can limit usage of lifecycle hooks and other features of Component Classes. recompose
helps solve this by providing Higher Order Component functions such as withContext
, lifecycle
, and withHandlers
.
import { connect } from 'react-redux'
import {
compose,
withHandlers,
lifecycle,
withContext,
getContext
} from 'recompose'
const withStore = compose(
withContext({ store: PropTypes.object }, () => {}),
getContext({ store: PropTypes.object }),
)
const enhance = compose(
withStore,
withHandlers({
loadData: props => () => props.store.firestore.get('todos'),
onDoneClick: props => (key, done = false) =>
props.store.firestore.update('todos', key, { done }),
onNewSubmit: props => newTodo =>
props.store.firestore.add('todos', { ...newTodo, owner: 'Anonymous' }),
}),
lifecycle({
componentWillMount(props) {
props.loadData()
}
}),
connect(({ firebase }) => ({ // state.firebase
todos: firebase.ordered.todos,
}))
)
export default enhance(SomeComponent)

import React, { Component } from 'react'
import PropTypes from 'prop-types'
import { connect } from 'react-redux'
import { isEqual } from 'lodash'
import { watchEvents, unWatchEvents } from './actions/query'
import { getEventsFromInput, createCallable } from './utils'
class Todos extends Component {
static contextTypes = {
store: PropTypes.object.isRequired
}
componentWillMount () {
const { firebase } = this.context.store
firestore.get('todos')
}
render () {
return (
<div>
{
todos.map(todo => (
<div key={todo.id}>
{JSON.stringify(todo)}
</div>
))
}
</div>
)
}
}
export default connect((state) => ({
todos: state.firestore.ordered.todos
}))(Todos)
props.store.firestore.get({ collection: 'cities' }),
// store.firestore.get({ collection: 'cities', doc: 'SF' }), // doc
store.firestore.onSnapshot({ collection: 'cities' }),
// store.firestore.setListener({ collection: 'cities' }), // alias
// store.firestore.setListener({ collection: 'cities', doc: 'SF' }), // doc
store.firestore.setListeners([
{ collection: 'cities' },
{ collection: 'users' },
]),
{ collection: 'cities' },
// or string equivalent
// store.firestore.get('cities'),
{ collection: 'cities', doc: 'SF' },
// or string equivalent
// props.store.firestore.get('cities/SF'),
{ collection: 'cities', doc: 'SF', subcollections: [{ collection: 'zipcodes' }] },
// or string equivalent
// props.store.firestore.get('cities/SF'),
To create a single where
call, pass a single argument array to the where
parameter:
{
collection: 'cities',
where: ['state', '==', 'CA']
},
Multiple where
queries are as simple as passing multiple argument arrays (each one representing a where
call):
{
collection: 'cities',
where: [
['state', '==', 'CA'],
['population', '<', 100000]
]
},
Should only be used with collections
To create a single orderBy
call, pass a single argument array to orderBy
{
collection: 'cities',
orderBy: ['state'],
// orderBy: 'state' // string notation can also be used
},
Multiple orderBy
s are as simple as passing multiple argument arrays (each one representing a orderBy
call)
{
collection: 'cities',
orderBy: [
['state'],
['population', 'desc']
]
},
Should only be used with collections
Limit the query to a certain number of results
{
collection: 'cities',
limit: 10
},
Should only be used with collections
Storing data under a different path within redux is as easy as passing the storeAs
parameter to your query:
{
collection: 'cities',
where: ['state', '==', 'CA'],
storeAs: 'caliCities' // store data in redux under this path instead of "cities"
},
NOTE: Not yet supported inside of subcollections (only at the top level)
Other Firebase statics (such as FieldValue) are available through the firestore instance:
import { connect } from 'react-redux'
import {
compose,
withHandlers,
lifecycle,
withContext,
getContext
} from 'recompose'
const withFirestore = compose(
withContext({ store: PropTypes.object }, () => {}),
getContext({ store: PropTypes.object }),
)
const enhance = compose(
withStore,
withHandlers({
onDoneClick: props => (key, done = true) => {
const { firestore } = props.store
return firestore.update('todos', key, {
done,
updatedAt: firestore.FieldValue.serverTimestamp() // use static from firestore instance
}),
}
})
)
export default enhance(SomeComponent)
Most commonly people consume Redux Firestore as a CommonJS module. This module is what you get when you import redux in a Webpack, Browserify, or a Node environment.
If you don't use a module bundler, it's also fine. The redux-firestore npm package includes precompiled production and development UMD builds in the dist folder. They can be used directly without a bundler and are thus compatible with many popular JavaScript module loaders and environments. For example, you can drop a UMD build as a <script>
tag on the page. The UMD builds make Redux Firestore available as a window.ReduxFirestore
global variable.
It can be imported like so:
<script src="../node_modules/redux-firestore/dist/redux-firestore.min.js"></script>
<!-- or through cdn: <script src="https://unpkg.com/redux-firestore@latest/dist/redux-firestore.min.js"></script> -->
<script>console.log('redux firestore:', window.ReduxFirestore)</script>
Note: In an effort to keep things simple, the wording from this explanation was modeled after the installation section of the Redux Docs.
- fireadmin.io - Firebase Instance Management Tool (source available here)
- Automatic support for documents that have a parameter and a subcollection with the same name (currently requires
storeAs
) - Support for Passing a Ref to
setListener
in place ofqueryConfig
object or string
