Initialization
Before using the capabilities of IMLib, you must first call the initialization interface of IMLib, and ensure that this interface is called only once during the entire lifecycle of the application.
The App Key is a necessary condition for using IMLib to develop instant messaging features and serves as the unique identifier of the application. Before integrating and using IMLib, make sure to register and obtain your exclusive App Key through the Console.
tip
Do not confuse the App Key for the development and production environments. Only when the App Key is the same can messages be exchanged between different users.
Use the init method for initialization and directly pass in the App Key.
// Application initialization, ensure this process is executed only once
RongIMLib.init({ appkey: '<Your-App-Key>' });
