Steps for How to Make a Group Chat with ZEGOCLOUD Chat SDK

Here comes the highly anticipated section of this article where we will delve into the process of creating a group chat feature using ZEGOCLOUD Chat SDK. Follow the steps outlined below to achieve this:

1. Integrate the SDK

Integrating ZEGOCLOUD’s In-chat SDK into your project is the first step to building a group chat app. You can accomplish this by following the steps below:

a. Install the required dependencies by running the command:

npm i @zegocloud/zimkit-vue

b. In your project’s main.js file, import ZIMKiti18n:

import { ZIMKiti18n } from '@zegocloud/zimkit-vue';

// Add i18n to the Vue instance.
new Vue({
i18n: ZIMKiti18n,

2. Initialize In-app Chat SDK and login

Creating an instance of the Chat Kit and initializing the SDK using the init method is essential to using ZEGOCLOUD’s In-app Chat UI components. Follow the steps below to do so:

// 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

Before initiating a one-on-one or group chat, you need to retrieve the userID of the peer user you want to chat with. Make sure that the user(s) you want to chat with have already logged in to the In-app Chat UIKit at least once; otherwise, you may face errors. Use your business logic to retrieve the userID and insert it into the code snippet below to execute the chat functionality.

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

4. Start a group chat

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

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

Get the groupID for the group chat you want to join using your business logic. Then fill in the groupID parameter in the code snippet below and execute it to join the chat. Ensure that the group chat already exists to avoid errors.

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