Example Apps

We have built five demo applications showcasing a variety of chat use cases, including social messaging, team collaboration, customer support, livestream gaming, and virtual event. You can preview these demos on our website. Also, the code is open source.

Docs

We use a doc generator to build our component documentation. We provide a brief description of each chat component and define all of the props it accepts.

The React components are created using the stream-chat-js library. If you're customizing the components, it's likely you'll need to make additional calls to our Chat API using our JavaScript client, which has documentation on our website.

TypeScript Support

As of version 5.0.0, the component library has been converted to TypeScript. Please read the TypeScript guide for details and implementation assistance.

Component Reusability

For components that implement significant logic, it's helpful to split the component into two parts: a top-level component which handles functionality and a lower level component which renders the UI. This way you can swap UI without altering the logic that gives the component its functionality. We use this provider/consumer pattern frequently in the library, and the below example shows how to swap out the Message UI component with MessageTeam, without affecting any logic in the app.

<Channel Message={MessageTeam}>
  <Window>
    <ChannelHeader />
    <MessageList />
    <MessageInput />
  </Window>
  <Thread />
</Channel>

Customizing Styles

The preferred method for overriding the pre-defined styles in the library is to two step process. First, import our bundled CSS into the file where you instantiate your chat application. Second, locate any Stream styles you want to override using either the browser inspector or by viewing the library code. You can then add selectors to your local CSS file to override our defaults. For example:

import 'stream-chat-css/dist/css/index.css';
import './App.css';

Internationalization

Our library supports auto-translation for various user languages. Please read our internationalization documentation for further details and setup guidance.
