该插件允许你捕获 Redux 的 actions/state，并在之后回放会话录制时进行检查。这对于理解和修复问题非常有用。

npm i @openreplay/tracker-redux --save

先初始化 tracker，然后将生成的中间件放入你的 Redux 链中。

import { applyMiddleware, createStore } from 'redux';
import OpenReplay from '@openreplay/tracker';
import trackerRedux from '@openreplay/tracker-redux';

const tracker = new OpenReplay({
  projectKey: PROJECT_KEY
});
tracker.start();
const openReplayMiddleware = tracker.use(trackerRedux(<options>)); // check list of available options below

//...
const store = createStore(
  reducer,
  applyMiddleware(openReplayMiddleware) 
);

如果你的应用是 SSR，请参照下面的示例。确保在应用启动后再调用 tracker.start()（在 useEffect 或 componentDidMount 中）。

import { applyMiddleware, createStore } from 'redux';
import OpenReplay from '@openreplay/tracker/cjs';
import trackerRedux from '@openreplay/tracker-redux/cjs';

const tracker = new OpenReplay({
  projectKey: PROJECT_KEY
});
const openReplayMiddleware = tracker.use(trackerRedux(<options>)); // check list of available options below


const store = createStore( // You can define/use it anywhere in response handlers
  reducer,
  applyMiddleware(openReplayMiddleware)
);

//...
function MyApp() {
  useEffect(() => { // use componentDidMount in case of React Class Component
    tracker.start();
  }, []);
  //... Use store here
}

你可以通过选项自定义中间件的行为，以净化你的数据。

trackerRedux({
  actionFilter: action => action.type !== 'DRAW', // only actions which pass this test will be recorded
  actionTransformer: action => action.type === 'LOGIN' ? null : action,
  actionType: action => action.type // action type for search, that's the default one
  stateTransformer: state => {
    const { jwt, ..._state } = state;
    return _state;
  },
})
