Code Example

import { getSDK } from '@openim/wasm-client-sdk';
const IMSDK = getSDK();

// use in electron with ffi
// import { getWithRenderProcess } from '@openim/electron-client-sdk/lib/render';
// const { instance: IMSDK } = getWithRenderProcess();

// use in mini program
// import { OpenIMSDK } from 'open-im-sdk';
// const IMSDK = new OpenIMSDK();

IMSDK.getAdvancedHistoryMessageList({
  lastMinSeq: 0,
  count: 20,
  startClientMsgID: '',
  conversationID: 'conversationID',
})
  .then(({ data }) => {
    // Call successful
