Steps on How to Build a Random Chat App with ZEGOCLOUD

In this section, you’ll learn how to create a random chat app using ZEGOCLOUD Chat SDK. Follow the instructions below to build your own app and connect with people from around the world:

1. Integrate the SDK

The first step to building a random chat app with ZEGOCLOUD is to integrate the In-chat SDK into your project. The following steps can be taken by you to accomplish this:

a. To install the dependencies:

npm i @zegocloud/zimkit-vue

b. Import ZIMKiti18n to your project’s main.js file.

import { ZIMKiti18n } from '@zegocloud/zimkit-vue';
// Add i18n to the Vue instance. 
new Vue({
    i18n: ZIMKiti18n,

2. Initialize In-app Chat SDK and login

To use In-app Chat UI components, create an instance of the Chat Kit and initialize the SDK with the init method. Login by calling connectUser with user info and Token, authentication must pass for successful login.

// Integrate the SDK using NPM
import { ZIMKitManager, Common } from '@zegocloud/zimkit-vue';
import '@zegocloud/zimkit-vue/index.css';

export default {
  name: 'App',
  components: {
  data() {
    return {
      appConfig: {
        appID: 0,        // The AppID you get from ZEGOCLOUD Admin Console.
        serverSecret: '' // The serverSecret you get from ZEGOCLOUD Admin Console.
     // The userID and userName is a strings of 1 to 32 characters. 
     // Only digits, letters, and the following special characters are supported: '~', '!', '@', '#', '$', '%', '^', '&', '*', '(', ')', '_', '+', '=', '-', '`', ';', ''', ',', '.', '<', '>', '/', '\'    
      userInfo: {
        // Your ID as a user.
        userID: '',
        // Your name as a user.
        userName: '',
        // The image you set as a user avatar must be a network image. e.g.,
        userAvatarUrl: ''
  async created() {
    const zimKit = new ZIMKitManager();
    const token = zimKit.generateKitTokenForTest(this.appConfig.appID, this.appConfig.serverSecret, this.userInfo.userID);
    await zimKit.init(this.appConfig.appID);
    await zimKit.connectUser(this.userInfo, token);

3. Start a one-on-one chat

Retrieve the userID using your business logic for the peer user you wish to chat with. Fill in the userID parameter in the code snippet below and execute it.

Note: To initiate a one-on-one or group chat successfully, ensure the peer user(s) you wish to chat with have logged in to the In-app Chat UIKit at least once. Otherwise, you may encounter errors.

createChat(userID: string) {
    ZIMKitChatListVM.getInstance().initWithConversationID(userID, ZIMKitConversationType.ZIMKitConversationTypePeer);

4. Start a group chat

Retrieve the userIDList and groupName for the users you want to add to the group chat using your business logic. Fill in the respective parameters in the code snippet below and execute it.

createGroupChat(groupName: string, userIDList: string[]) {
        .createGroup(groupName, userIDList)
        .then((data) => {
            const { groupInfo, errorUserList } = data;
            const { baseInfo } = groupInfo;
            if (errorUserList.length) {
                // Implement the logic for the prompt window based on your business logic when there is a non-existing user ID in the group.

            } else {
                // Directly enter the chat page when the group chat is created successfully.
                const groupID = baseInfo.groupID
                ZIMKitChatListVM.getInstance().initWithConversationID(groupID,  ZIMKitConversationType.ZIMKitConversationTypeGroup);
        }).catch((error) => {
            // Implement the logic for the prompt window based on the returned error info when failing to create a group chat.

5. Join a group chat

Retrieve the groupID for the group chats you wish to join using your business logic. Fill in the groupID parameter in the code snippet below and execute it.

joinGroupChat(groupID: string) {
        .then((data) => {
            const groupID = data.groupInfo.baseInfo.groupID;
            ZIMKitChatListVM.getInstance().initWithConversationID(groupID, ZIMKitConversationType.ZIMKitConversationTypeGroup);
