Getting Started with GetStream.io
Step 1: Sign Up and Create an App
First, you'll need to sign up for a GetStream.io account. Once you've registered, create a new app in the GetStream.io dashboard. This will provide you with the necessary API keys to connect your application to the GetStream.io service.
Step 2: Install the SDK
Next, install the GetStream.io SDK for your platform. For a React application, you can use the following command:
npm install stream-chat-react
Step 3: Initialize the Client
Initialize the GetStream.io client in your application using the API key you received:
import { StreamChat } from 'stream-chat';
const client = StreamChat.getInstance('YOUR_API_KEY');
Step 4: Connect a User
To interact with the chat service, you'll need to connect a user. You'll typically do this after a user logs into your application:
client.connectUser(
{
id: 'user-id',
name: 'User Name',
image: 'https://path-to-avatar/image.jpg',
},
userToken // Token generated for the user
);
Step 5: Create or Join a Channel
Now, let's create or join a chat channel:
const channel = client.channel('messaging', 'channel-id', {
name: 'General Chat',
});
await channel.watch();
Step 6: Send and Receive Messages
With the channel set up, you can now send and receive messages:
// Sending a message
await channel.sendMessage({
text: 'Hello, world!',
});
// Receiving messages
channel.on('message.new', (event) => {
console.log(event.message);
});
Step 7: Implement UI Components
GetStream.io provides pre-built React components for common chat features, making it easy to create a polished chat interface. Here's a basic example using the Channel
and MessageList
components:
import { Chat, Channel, ChannelHeader, MessageList, MessageInput } from 'stream-chat-react';
import 'stream-chat-react/dist/css/index.css';
const App = () => (
<Chat client={client} theme="messaging light">
<Channel channel={channel}>
<ChannelHeader />
<MessageList />
<MessageInput />
</Channel>
</Chat>
);
