Installing Angular UI Kit

Setup

1. Register on CometChat
   a. To install the Angular UI Kit, you need to first register on the CometChat Dashboard. Click here to sign up

2. Get Your Application Keys 🔑

   • Create a new app
   • Head over to the QuickStart or API & Auth Keys section and note the App ID, Auth Key, and Region.

3. Add the CometChat Dependency

CLI

npm install @cometchat-pro/chat@2.4.0 --save

Configure CometChat inside your app

• Import CometChat SDK

JavaScript

import { CometChat } from "@cometchat-pro/chat";

• Initialize CometChat 🌟 The init() method initializes the settings required for CometChat. We suggest calling the init() method on app startup, i.e main.ts file of the application.

JavaScript

const appID = "APP_ID";
const region = "REGION";
const appSetting = new CometChat.AppSettingsBuilder()
  .subscribePresenceForAllUsers()
  .setRegion(region)
  .build();
CometChat.init(appID, appSetting).then(
  () => {
    console.log("Initialization completed successfully");
    // You can now call login function.
  },
  (error) => {
    console.log("Initialization failed with error:", error);
    // Check the reason for error and take appropriate action.
  }
);

Replace APP_ID and REGION with your CometChat App ID and Region in the above code

• Create user This method takes a User object and the Auth Key as input parameters and returns the created User object if the request is successful.

JavaScript

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);
    }
)

• Login your user 👤

This method takes UID and Auth Key as input parameters and returns the User object containing all the information of the logged-in user

JavaScript

const authKey = "AUTH_KEY";
const uid = "cometchat-uid-1";

CometChat.login(uid, authKey).then(
  (user) => {
    console.log("Login Successful:", { user });
  },
  (error) => {
    console.log("Login failed with exception:", { error });
  }
);

Replace AUTH_KEY with your CometChat Auth Key in the above code.

We have set up 5 users for testing having UIDs: cometchat-uid-1, cometchat-uid-2, cometchat-uid-3, cometchat-uid-4, and cometchat-uid-5.

We have used uid cometchat-uid-1 as an example here. You can create a User from CometChat Dashboard as well.

Add UI Kit to your project

• Clone this repository

CLI

git clone https://github.com/cometchat-team/cometchat-pro-angular-ui-kit.git -b v2

• Copy the cloned repository into your project src folder.

• Import the Components in the respective module where the component will be used.
• Install @ctrl/ngx-emoji-mart according to the angular version of your project @ctrl/ngx-emoji-mart
• Add these styles to your angular.json
• Wrap all the selectors in a div with class=responsive as shown in the next step
