import * as Ably from "ably";
import { ChatClient, MessageEvent } from "@ably/chat";
// Initialize Ably Realtime client
const ablyClient = new Ably.Realtime({
key: "<API_KEY>",
clientId: "ably-chat",
});
// Create an Ably Chat client instance
const chatClient = new ChatClient(ablyClient);
// Get or create a chat room
const room = await chatClient.rooms.get("my-chat-room");
// Subscribe to incoming messages
room.messages.subscribe((event: MessageEvent) => {
console.log("Received message:", event.message.text);
});
// Attach to the room to start receiving messages
await room.attach();
// Send a message
await room.messages.send({ text: "Hello, World!" });
