The live e-commerce broadcasting component results from the secondary encapsulation of Instant Messaging (IM) capabilities used in the live streaming scenario. Capabilities, such as likes, gifts, product push, and coupon claiming, are encapsulated specifically for the live streaming scenario. For how to download the related SDK, see Downloading the SDK.

Prerequisites for Using the Component

• You have created an IM app.
• The following group custom field is created.
  • attent: records the hosts that you have followed.
• You have created the following group member custom fields.
  • add_goods: lists newly released products on the backend in the live room.
  • room_status: controls the status of the live room.

SDK Integration

• Run the following command to integrate the IM SDK.

  npm i tim-wx-sdk --save

• Run the following command to integrate the livestream marketing SDK.

  npm i im-live-sells --save

Component Parameters

Parameter	Description
SDKAppID	ID of the IM app. The SDKAppID should be created in the IM console. By default, new apps are Trial Edition apps, which are mainly used for integration and testing. We recommend that you upgrade to Pro Edition or Flagship Edition before launching your app.
userSig	UserSig of the IM user. This parameter is required for logging in to the IM SDK. A UserSig can be generated at the business backend and then sent to the frontend for use. For more information on the methods and code for generating a UserSig, see Generating UserSig.
roomID	ID of the chat room. It indicates the ID of the livestreaming group (AVChatRoom) created in IM. An AVChatRoom supports an unlimited number of members and can be created in the IM Consoloe or via the REST API.
TIM	IM SDK. You need to use tim-wx-sdk* in a Mini Program environment and **tim-js-sdk in a web environment.
userName	This parameter is consistent with the userName of the generated UserSig.

Initialization Example

import TIMLiveSell from 'im-live-sell'
import TIM from 'tim-js-sdk' // Web environment
import TIM from 'tim-wx-sdk' // Mini Program environment
const tls = new TIMLiveSell({
      SDKAppID: 1400***803,
      roomID: '@TGS#E****NVLGE',
      userSig: 'eJwtzM9****-reWMQw_',
      userName: 'Ho***st',
      TIM: TIM
})

Component Callbacks

TLS.EVENT.SDK_READY

This callback is triggered when the initialization of the component is completed. This event corresponds to TIM.EVENT.SDK_READY of the IM SDK. You can call the SDK methods only after this callback is triggered.

tls.on(TLS.EVENT.SDK_READY, async() => {

})

TLS.EVENT.ROOM_STATUS_CHANGE

This callback is triggered when the room status changes, for example, when the host goes online or offline or pauses the stream.

tls.on(TLS.EVENT.ROOM_STATUS_CHANGE, async(data) => {

}

TLS.EVENT.JOIN_GROUP

This callback is triggered when a user joins the group.

tls.on(TLS.EVENT.JOIN_GROUP, async(data) => {
  const {nick,avatar,userID} = data
})

TLS.EVENT.EXIT_GROUP

This callback is triggered when a user exits the group.

tls.on(TLS.EVENT.EXIT_GROUP, async(data) => {
  const {nick,avatar,userID} = data
})

TLS.EVENT.NOTIFACATION

This callback is triggered when the group notification is changed.

tls.on(TLS.EVENT.NOTIFACATION, async(data) => {
  const { notification } = data
})

TLS.EVENT.MESSAGE

This callback is triggered when a user sends a group message.

Messages that you send yourself cannot be found through this callback. To display messages you sent on the screen, use the data returned by the sendMessage method. This is consistent with the IM SDK.

tls.on(TLS.EVENT.MESSAGE, async(data) => {
  const { nick,avatar,message,userID } = data
})

TLS.EVENT.LIKE

This callback is triggered when a user likes the host.

tls.on(TLS.EVENT.LIKE, async(data) => {
  const { nick,avatar,value,userID } = data
})

TLS.EVENT.SEND_GIFT

This callback is triggered when a user sends a gift to the host.

tls.on(TLS.EVENT.SEND_GIFT, async(data) => {
  const { nick,avatar,value,userID } = data
})

TLS.EVENT.ATTENT

This callback is triggered when a user follows the host.

tls.on(TLS.EVENT.ATTENT, async(data) => {
  const { nick,avatar,value,userID } = data
})

TLS.EVENT.BUY_GOODS

This callback is triggered when a user purchases a product.

tls.on(TLS.EVENT.BUY_GOODS, async(data) => {
  const { nick,avatar,value,userID } = data
})

TLS.EVENT.USE_COUPON

This callback is triggered when a user claims a coupon.

tls.on(TLS.EVENT.USE_COUPON, async(data) => {
  const { nick,avatar,value,userID } = data
})

TLS.EVENT.ADD_GOODS

This callback is triggered when the product recommended in the livestream changes.

tls.on(TLS.EVENT.ADD_GOODS, async(data) => {
  const { nick,avatar,value } = data
})

TLS.EVENT.KICKED

This callback is triggered when the account is used for login on another device.

tls.on(TLS.EVENT.KICKED, async() => {

})

TLS.EVENT.NETWORK_CHANGE

This callback is triggered when the network changes.

tls.on(TLS.EVENT.NETWORK_CHANGE, async() => {

})

TLS.EVENT.SDK_NOT_READY

This callback is triggered when the SDK is not ready.

tls.on(TLS.EVENT.SDK_NOT_READY, async() => {

})

TLS.EVENT.PROFILE_UPDATE

This callback is triggered when the personal profile is updated.

tls.on(TLS.EVENT.PROFILE_UPDATE, async() => {

})

TLS.EVENT.ERROR

This callback is triggered when the SDK encounters an error.

tls.on(TLS.EVENT.ERROR, async(error) => {

})

${type}

This is the event with the same name that is triggered when a custom message is called.

tls.on(`${type}`, async(error) => {

})
