Introduction to chat-uikit-react

chat-uikit-react is a react UI component library based on Tencent Cloud Chat SDK. It provides some common UI components, including features for conversation, chat, and group. Based on the well-designed UI components, you can quickly build elegant, reliable, and scalable Chat applications. The interface of chat-uikit-react is shown in the figure below:
You can experience it online:
Web Demo
H5 Demo
TUIKit Web interface is shown in the following figure:

TUIKit H5 interface is shown in the following figure:


Environment Requirements

React v18.0 (Version 17.x is not supported.)
TypeScript
Node (The Node version should not be earlier than 12.13.0 and not later than 17.0.0. The official LTS version 16.17.0 of Node.js is recommended.)
npm (Use a version that matches the Node version in use.)

chat-uikit-react Integration

Step 1: Create a project

Create a new React project. You can choose whether to use a TS template or not.
npx create-react-app sample-chat --template typescript
After the project is created, go to the project directory.
cd sample-chat

Step 2: Download the chat-uikit-react component

Use npm to download chat-uikit-react and use it in your project. Additionally, related open source code is also provided on GitHub, which you can use as a basis to develop your own component library.
npm install @tencentcloud/chat-uikit-react

Step 3: Include the chat-uikit-react component

Note:
In the following code, SDKAppID, userID, and userSig are not input. Acquire the necessary information in Step 4 and replace it accordingly.
npm Integration Method
Source Code Integration Method
Replace the content in App.tsx, or you can create a new component for inclusion.
import React, { useEffect, useState } from 'react';
import { ChatSDK } from '@tencentcloud/chat';
import { TUIKit } from '@tencentcloud/chat-uikit-react';
import { TUILogin } from '@tencentcloud/tui-core';
import '@tencentcloud/chat-uikit-react/dist/cjs/index.css';

export default function SampleChat() {
const [chat, setChat] = useState<ChatSDK>();
const init = () => {
const loginInfo = {
SDKAppID: 0, // Your SDKAppID. Get it from Step 4
userID: 'xxx', // Your userID. Get it from Step 5
// UserSig is a cipher for a user to log in to IM. It is the ciphertext generated by
//encrypting information such as userID. Get it from Step 5
userSig: 'xxx', // Your userSig. Get it from Step 5
useUploadPlugin: true,
};
TUILogin.login(loginInfo).then(() => {
const { chat } = TUILogin.getContext();
setChat(chat);
}).catch(() => {});
}
useEffect(() => {
init();
}, [])


return (
<TUIKit chat={chat} language={'en'}></TUIKit> // language support en or zh
)
}
1. Copy UIKit to the src directory of your own project:
macOS
Windows
mkdir -p ./src/TUIKit && rsync -av ./node_modules/@tencentcloud/chat-uikit-react/ ./src/TUIKit
xcopy .\node_modules\@tencentcloud\chat-uikit-react .\src\TUIKit /i /e
2. Replace the content in App.tsx, or you can create a new component for inclusion.
import React, { useEffect, useState } from 'react';
import { ChatSDK } from '@tencentcloud/chat';
import { TUILogin } from '@tencentcloud/tui-core';
import { TUIKit } from './TUIKit/index';

export default function SampleChat() {
const [chat, setChat] = useState<ChatSDK>();
const init = () => {
const loginInfo = {
SDKAppID: 0, // Your SDKAppID. Get it from Step 4
userID: 'xxx', // Your userID. Get it from Step 5
// UserSig is a cipher for a user to log in to IM. It is the ciphertext generated by
// encrypting information such as userID. Get it from Step 5
userSig: 'xxx', // Your userSig. Get it from Step 5
useUploadPlugin: true,
};
TUILogin.login(loginInfo).then(() => {
const { chat } = TUILogin.getContext();
setChat(chat);
}).catch(() => {});
}
useEffect(() => {
init();
}, [])


return (
<TUIKit chat={chat} language={'en'}></TUIKit> // language support en or zh
)
}

Step 4: Create an application

1. Log in to the IM console.
2. Click Create Application, enter your application name, and then click Create.

3. After creation is complete, you can view the status, service version, SDKAppID, creation time, tag, and expiration time of the new application on the console overview page.


Step 5: Obtain userID and userSig

Click the target application tab, enter the Account Management page, create an account, and obtain userID.

Go to the IM console > UserSig Tools , enter the userID to generate a userSig, and copy the userSig. For more information about userSig, see Generating UserSig.


Step 6: Start the project

Replace SDKAppID, userID, and userSig in App.tsx, and then run the following command:
npm run start
Note:
1. Ensure that SDKAppID, userID, and userSig are successfully replaced in Step 3, as the failure to do so may cause the project to operate abnormally.
2. A userID corresponds to a userSig. For more information, see Generating UserSig.
3. If the project fails to start, please check whether the environment requirements are met.

Step 7: Send your first message

1. After starting the project, click + on the left to start a one-to-one chat.
2. Enter the userID created in Step 5 in the search box, and then press Enter.
3. Enter your message in the input box and press Enter to send.


FAQs

What is UserSig?

A UserSig is a cipher with which you can log in to IM. It is the ciphertext generated by encrypting information such as userID.

How can I generate a UserSig?

The issuance method for UserSig involves integrating the computation code of UserSig into your server, and providing an API oriented towards your project. When UserSig is needed, your project sends a request to the business server to obtain the dynamic UserSig. For more information, see How to Generate a UserSig on the Server.
Note:
The sample code provided in this document retrieves the UserSig by embedding the secret key in the client code. This approach makes the secret key highly susceptible to decompilation and reverse engineering. Once your key is compromised, attackers can misappropriate your Tencent Cloud traffic. Hence, this approach is exclusively recommended for debugging features locally. For the correct issuance of UserSig, please refer to the previous sections.
