AI Integration Quick Reference

npm install @cometchat/chat-sdk-react-native

import { CometChat } from "@cometchat/chat-sdk-react-native";

// 1. Initialize (once at app startup)
const appSettings = new CometChat.AppSettingsBuilder()
  .setRegion("APP_REGION") // e.g. "us", "eu", "in"
  .subscribePresenceForAllUsers()
  .autoEstablishSocketConnection(true)
  .build();

await CometChat.init("APP_ID", appSettings);

// 2. Login (check session first)
const existing = await CometChat.getLoggedinUser();
if (!existing) {
  await CometChat.login("cometchat-uid-1", "AUTH_KEY"); // dev only — use Auth Token in production
}
