Installation

npm install @tencentcloud/chat --save
// The upload plugin is required to send messages such as images and files.
npm install tim-upload-plugin --save

Getting started

import TencentCloudChat from '@tencentcloud/chat';
import TIMUploadPlugin from 'tim-upload-plugin';

// Create an SDK instance. 
// The `TencentCloudChat.create()` method returns the same instance for the same `SDKAppID`.
// The SDK instance is usually represented by `chat`.
let chat = TencentCloudChat.create({
  SDKAppID: 0 // Replace `0` with the `SDKAppID` of your Chat app during access.
}); 

// Common level. You are advised to use this level during connection as it covers more logs.
chat.setLogLevel(0);
// Release level, at which the SDK outputs important information.
// You are advised to use this log level in a production environment.
// chat.setLogLevel(1);

// Register the Tencent Cloud Chat upload plugin.
chat.registerPlugin({'tim-upload-plugin': TIMUploadPlugin});

Sending your first message

1. Generate UserSig

UserSig is a password used to log in to Tencent Cloud Chat. It is the ciphertext obtained after data such as UserID is encrypted. This document describes how to generate a UserSig.

2. Listen to the SDK_READY event

// This event is triggered when the SDK enters the ready state.
// When SDK is ready, the access side can call SDK APIs such as the message sending API to use various features of the SDK
let onSdkReady = function(event) {
  // Now you can create a message instance and send it.
};
chat.on(TencentCloudChat.EVENT.SDK_READY, onSdkReady);

let onMessageReceived = function(event) {
  // A newly pushed one-to-one message, group message, group tip, or group system notification is received. You can traverse event.data to obtain the message list and render it to the UI.
  // event.name - TencentCloudChat.EVENT.MESSAGE_RECEIVED
  // event.data - An array that stores Message objects - [Message]
};
chat.on(TencentCloudChat.EVENT.MESSAGE_RECEIVED, onMessageReceived);

3. Login in to the Chat SDK

let promise = chat.login({userID: 'your userID', userSig: 'your userSig'});
promise.then(function(imResponse) {
  console.log(imResponse.data); // Login successful
  if (imResponse.data.repeatLogin === true) {
    // Indicates that the account has logged in and that the current login will be a repeated login.
    console.log(imResponse.data.errorInfo);
  }
}).catch(function(imError) {
  console.warn('login error:', imError); // Error information
});

After successful login, to call APIs that require authentication, such as sendMessage, you must wait until the SDK enters the ready state (you can obtain the status of the SDK by listening to the TencentCloudChat.EVENT.SDK_READY event.

3. Create a message instance

let message = chat.createTextMessage({
  to: 'user1',
  conversationType: TencentCloudChat.TYPES.CONV_C2C,
  payload: {
    text: 'Hello Tencent!'
  },
  // Message custom data (saved in the cloud, will be sent to the peer end, and can still be pulled after the app is uninstalled and reinstalled)
  // cloudCustomData: 'your cloud custom data'
});

4. Send the message instance

let promise = chat.sendMessage(message);
promise.then(function(imResponse) {
  // The message is sent successfully.
  console.log(imResponse);
}).catch(function(imError) {
  // The message fails to be sent.
  console.warn('sendMessage error:', imError);
});
