Initialize CometChat

The init() method initialises the settings required for CometChat. The init() method takes the below parameters:
  1. appID - You CometChat App ID
  2. appSettings - An object of the AppSettings class can be created using the AppSettingsBuilder class. The region field is mandatory and can be set using the setRegion() method.
The AppSettings class allows you to configure two settings: You need to call init() before calling any other method from CometChat. We suggest you call the init() method on app startup, preferably in the index.js file.
  • JavaScript
let appId = "APP_ID";
let region = "REGION";
let appSetting = new CometChat.AppSettingsBuilder()
                        .subscribePresenceForAllUsers()
                        .setRegion(region)
                        .build();
CometChat.init(appId, appSetting).then(
	() => {
		console.log("Initialization completed successfully");
	}, error => {
		console.log("Initialization failed with error:", error);
	}
);
Make sure you replace the APP_ID with your CometChat App ID and REGION with your App Region in the above code.
