Configure CometChat React Native SDK

i. Initialize CometChat 🌟

We suggest you call the init() method on app startup, preferably in the index.js file.

var appID = "APP_ID";
var region = "REGION";
var 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);
  }
);

ℹ️   Note: Make sure to replace region and appID with your credentials.

ii. Create User 👤

Once initialisation is successful, you will need to create a user. You need to use createUser() method to create user on the fly.

let authKey = "AUTH_KEY";
var uid = "user1";
var name = "Kevin";

var user = new CometChat.User(uid);

user.setName(name);

CometChat.createUser(user, authKey).then(
  user => {
    console.log("user created", user);
  },error => {
    console.log("error", error);
  }
);

ℹ️ Note: Make sure that UID and name are specified as these are mandatory fields to create a user.

---

iii. Login User 👤

Once you have created the user successfully, you will need to log the user into CometChat using the login() method.

var UID = "SUPERHERO1";
var authKey = "AUTH_KEY";

CometChat.getLoggedinUser().then(
  user => {
    if(!user){
      CometChat.login(UID, authKey).then(
        user => {
          console.log("Login Successful:", { user });    
        },
        error => {
          console.log("Login failed with exception:", { error });    
        }
      );
    }else{
      // User already logged in
    }
  }, error => {
    console.log("getLoggedinUser failed with exception:", { error });
  }
);

ℹ️   Note - The login() method needs to be called only once. Also replace AUTH_KEY with your App Auth Key.
