react-firestore React components to fetch collections and documents from Firestore
The problem
You want to use the new Firestore database from Google, but don't want to have to use redux or any other state management tool. You would like to not have to worry too much about the exact API for firestore (snapshots, references, etc), and just be able to retrieve collections and documents and read their data.
You also want to do all this using render props, because they're awesome.
The solution
This is a set of components that allows you to interact with Firestore collections
and documents, without needing to constantly call additional methods (like .data()
)
to display your data.
There is still an escape hatch where the snapshot from Firestore is provided to your render function, in the event that you need more control over your interactions with Firestore.
Disclaimer
This project is still a work in progress and in an alpha state. The API may update frequently.

Installation
This package is available on npm.
npm install --save @green-arrow/react-firestore
Or, if you're using yarn:
yarn add @green-arrow/react-firestore
Usage
There are 3 components provided with this package:
FirestoreProvider
This component allows the FirestoreCollection
and FirestoreDocument
components to communicate with Firestore.
At the top level of your app, configure firebase
and render the
FirestoreProvider
component.
If you're using create-react-app, your index.js
file would look something like this:
import React from 'react';
import ReactDOM from 'react-dom';
import firebase from '@firebase/app';
import '@firebase/firestore';
import App from './App';
const config = {
apiKey: '<your_api_key>',
projectId: '<your_firebase_project_id>',
};
firebase.initializeApp(config);
ReactDOM.render(
<FirestoreProvider firebase={firebase}>
<App />
</FirestoreProvider>,
document.getElementById('root')
);
Note: The reason for the separate imports for @firebase/app
and @firebase/firestore
is because firestore
is not included in the default firebase
wrapper package. See
the firestore package for more details.
FirestoreProvider
props
firebase
firebase
| required
An already initialized firebase
object from the @firebase/app package.
FirestoreCollection
This component allows you to interact with a Firestore collection.
Using this component, you can access the collection at a given path
and provide sort options, perform queries, and paginate data.
This component will setup a listener and update whenever the given collection is updated in Firestore.
Example usage to get a collection and sort by some fields:
<FirestoreCollection
path="stories"
sort="publishedDate:desc,authorName"
render={({ isLoading, data }) => {
return isLoading ? (
<Loading />
) : (
<div>
<h1>Stories</h1>
<ul>
{data.map(story => (
<li>
{story.title} - {story.authorName}
</li>
))}
</ul>
</div>
);
}}
/>
FirestoreCollection
props
path
string
| required
The /
separated path to the Firestore collection. Collections must
contain an odd number of path segments.
sort
string
| defaults tonull
A comma-delimited list of fields by which the query should be ordered.
Each item in the list can be of the format fieldName
or fieldName:sortOrder
.
The sortOrder
piece can be either asc
or desc
. If just a field name is given,
sortOrder
defaults to asc
.
render
function({}) | required
This is the function where you render whatever you want based on the state of
the FirebaseCollection
component. The object provided to the render
function
contains the following fields:
property | type | description |
---|---|---|
isLoading | boolean | Loading status for the firebase query. true until an initial payload from Firestore is received. |
data | Array | An array containing all of the documents in the collection. Each item will contain an id along with the other data contained in the document. |
FirestoreDocument
This component allows you to retrieve a Firestore document from the given path
.
This component will setup a listener and update whenever the given document is updated in Firestore.
<FirestoreDocument
path="stories/1"
render={({ isLoading, data }) => {
return (
<div>
<h1>{data.title}</h1>
<h2>
{data.authorName} - {data.publishedDate}
</h2>
<p>{data.description}</p>
</div>
);
}}
/>
FirestoreDocument
props
path
string
| required
The /
