传奇观察者和打字稿问题

Question

在观察者中定义多个传奇时遇到打字稿问题，我经常看到这种模式：

// foo.JS
export function *fooSagas() {
  yield all([
    takeEvery("FOO_A", fooASaga),
    takeEvery("FOO_B", fooBSaga),
  ]);
}

但是当我尝试在打字稿文件中执行此操作时，我得到以下信息：

// foo.TS
export function *fooSagas() {
  yield all([
    takeEvery("FOO_A", fooASaga),
    /* 
      all subsequent calls throw this typescript error: 
      The last overload gave the following error.
      Argument of type 'string' is not assignable to parameter of type 'TakeableChannel<unknown>
      effects.d.ts(291, 17): The last overload is declared here.
    */
    takeEvery("FOO_B", fooBSaga),
  ]);
}

Answer 1

发帖是为了节省别人的时间... 显然这只是打字稿。

在每行之前添加 // @ts-ignore，一切正常

    yield all ([
      // @ts-ignore      
      takeLatest(ACT.todo.saga.create, create),
      // @ts-ignore      
      takeLatest(ACT.todo.saga.retrieve, retrieve),
      // @ts-ignore      
      takeLatest(ACT.todo.saga.update,update),
      // @ts-ignore      
      takeLatest(ACT.todo.saga.delete,del),
      // @ts-ignore      
      takeLatest(ACT.todo.saga.list, list)     
    ])

你可以在这里找到更好的答案 https://github.com/redux-saga/redux-saga/issues/1883 在 chenghw 于 2019 年 7 月 9 日发表的评论中。

In the generator, you are currently declaring the action as { payload: ICredential }without a type. If you declare the type, I think you will get rid of that error...so something like this...{ type: typeof types.USER_LOGIN_REQUEST; payload: ICredential; }
