【问题描述】：

我正在从 Redux 迁移到 Redux Toolkit。我这里的简化代码用于使用 lodash/debounce 进行去抖动更新。

import debounce from "lodash/debounce";

const updateApplication = async (app, dispatch) => 
const state = getState();

try 
  const result = await update(app);
  dispatch(
    type: UPDATE,
    result: result
  );
     catch (err) 
    console.log(err);
    
  ;

export default debounce(updateThunk, 2000);

问题是当我转到 createAsyncThunk 时，它没有被执行。

const updateApp = createAction("app/update");
const updateApplication = createAsyncThunk(
  "app/updateDebounced",
  async (app,  dispatch ) => 
   
    try 
      const result = await update(app);
          dispatch(updateApp(result))
        );
      
     catch (err) 
      // console.log(err);
    
  
);

export default debounce(updateApplication, 2000)

如何让它发挥作用？

【参考方案1】：

const updateApp = createAction("app/update");
const handler = async (app,  dispatch ) => 
    try 
      const result = await update(app);
          dispatch(updateApp(result))
        );
      
     catch (err) 
      // console.log(err);
    
  
const debouncedHandler = debounce(handler, 2000);

export default createAsyncThunk(
  "app/updateDebounced",
  debouncedHandler
);
