stream-js is the official JavaScript client for Stream, a web service for building scalable newsfeeds and activity streams.
Note that there is also a higher level Node integration which hooks into your ORM.
You can sign up for a Stream account at https://getstream.io/get_started.
💡 Note: this is a library for the Feeds product. The Chat SDKs can be found here.
npm install getstreamor if you are using yarn
yarn add getstream<script src="https://cdn.jsdelivr.net/npm/getstream/dist/js_min/getstream.js"></script>
⚠️ This will pull the latest which can be breaking for your application. Always pin a specific version as follows:
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js_min/getstream.js"></script>
⚠️ Beware about the version you're pulling. It's the latest by default which can break your app anytime.
Documentation for this JavaScript client are available at the Stream website.
This package can be integrated into React Native applications. Remember to not expose the App Secret in browsers, "native" mobile apps, or other non-trusted environments.
import { connect } from 'getstream';
// or if you are on commonjs
const { connect } = require('getstream');
// Instantiate a new client (server side)
const client = connect('YOUR_API_KEY', 'API_KEY_SECRET');
// Optionally supply the app identifier and an options object specifying the data center to use and timeout for requests (15s)
const client = connect('YOUR_API_KEY', 'API_KEY_SECRET', 'APP_ID', { location: 'us-east', timeout: 15000 });If you want to use the API client directly on your web/mobile app you need to generate a user token server-side and pass it.

const client = connect('YOUR_API_KEY', 'API_KEY_SECRET');

// Create a token for user with id "the-user-id"
const userToken = client.createUserToken('the-user-id');
⚠️ Client checks if it's running in a browser environment with a secret and throws an error for a possible security issue of exposing your secret. If you are running backend code in Google Cloud or you know what you're doing, you can specifybrowser: falseinoptionsto skip this check.

});Stream uses Faye for realtime notifications. Below is quick guide to subscribing to feed changes
const { connect } = require('getstream');
// ⚠️ userToken is generated server-side (see previous section)
const client = connect('YOUR_API_KEY', userToken, 'APP_ID');
const user1 = client.feed('user', '1');
// subscribe to the changes
const subscription = user1.subscribe(function (data) {
console.log(data);
});
// now whenever something changes to the feed user 1
// the callback will be called
// To cancel a subscription you can call cancel on the
// object returned from a subscribe call.
// This will remove the listener from this channel.
subscription.cancel();Docs are available on GetStream.io.
