Installing CometChat React Native SDK

Setup :wrench:

To setup React Native SDK, you need to first register on CometChat Dashboard. Click here to sign up.

i. Get your Application Keys :key:

Signup for CometChat and then:

Create a new app: Click Add App option available → Enter App Name & other information → Create App
At the Top in QuickStart section you will find Auth Key & App ID or else you can head over to the API & Auth Keys section and note the Auth Key and App ID

ii. Add the CometChat Dependency

	npm install @cometchat-pro/react-native-chat@3.0.11 --save

You can refer to the below link for instructions on how to do so: 📝 Add CometChat Dependency

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);
  }
);

:information_source: 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);
  }
);

:information_source: 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 });
  }
);

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