IM（インスタントメッセージング）

import FeiyanIM from '@feiyan/im-sdk';

// 1. Init: get the AppID from the app details in the console
const im = FeiyanIM.init({ appId: 'YOUR_APP_ID' });

// 2. Connect (auto-reconnect after a drop, offline messages are re-delivered)
await im.connect({ userId: 'user_1001', token });

// 3. Send a message: one API for direct chats, groups and chat rooms
await im.sendMessage({
  target: 'group_2001',
  type: 'text',
  content: 'Hello, FeiyanCloud',
});

// 4. Listen for messages and read receipts
im.on('message', (msg) => console.log(msg));
im.on('readReceipt', (r) => {
  console.log(`${r.readCount}/${r.totalCount}`, r.readUserIds);
});
