Getting Started

To begin using stream-chat-react, you’ll need to install it along with its dependencies. Here’s how you can do that:

Installation via NPM

To install the necessary packages using npm, run:

npm install react react-dom stream-chat stream-chat-react

Installation via Yarn

If you prefer using Yarn, execute:

yarn add react react-dom stream-chat stream-chat-react

CDN Installation

For quick setups without package managers, you can include the library via CDN:

<script src="https://cdn.jsdelivr.net/npm/react@16.13.1/umd/react.production.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/react-dom@16/umd/react-dom.production.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/stream-chat"></script>
<script src="https://cdn.jsdelivr.net/npm/stream-chat-react"></script>

Basic Implementation

Setting Up Your Chat Client

To start using stream-chat-react, you first need to create a client instance and set up the provider. Here’s how you can do that:

import React from 'react';
import { Chat } from 'stream-chat-react';
import { StreamChat } from 'stream-chat';

const client = StreamChat.getInstance('YOUR_API_KEY');

const App = () => {
  return (
    <Chat client={client} theme="messaging light">
      {/* Your chat components will go here */}
    </Chat>
  );
};

export default App;

In this code snippet, replace 'YOUR_API_KEY' with your actual API key from Stream. This sets up the basic structure for your chat application.

Creating Channels and Sending Messages

Once your client is set up, you can create channels and send messages. Here’s an example of how to create a channel and send a message:

const channel = client.channel('messaging', 'general', {
  name: 'General Chat',
});

await channel.create();
await channel.sendMessage({
  text: 'Hello World!',
});

This code creates a new channel called ‘General Chat’ and sends an initial message.

Advanced Customizations

Customizing Message Components

You can customize how messages are displayed by creating your own message component. Here’s an example:

import { MessageSimple } from 'stream-chat-react';

const CustomMessage = (props) => {
  return (
    <div style={{ padding: '10px', backgroundColor: '#f0f0f0' }}>
      <MessageSimple {...props} />
    </div>
  );
};

// Usage within Channel component
<Channel Message={CustomMessage}>
  {/* Other components */}
</Channel>

This customization allows you to style messages according to your application’s design requirements.

Handling User Presence

The library also allows you to manage user presence easily. You can display online/offline status with minimal effort:

<Channel>
  <Window>
    <ChannelHeader />
    <MessageList />
    <MessageInput />
  </Window>
  <Thread />
</Channel>

By incorporating presence indicators, users can see who is online, enhancing engagement within your application.
