返回`yield call`的类型

Question

我注意到yield call效果的结果是any在用作时输入的

const data = yield call(f);

虽然f是一个() => Promise<number>功能.

我错过了什么或是否是一种redux-saga打字限制？

Answer 1

检查这个正在进行的线程,tldr; 这是打字稿限制

Answer 2

与此同时，您可以使用这个包：typed-redux-saga

前

import { call, all } from "redux-saga/effects";
...
// Api.fetchUser return User
// but user has type any
const user = yield call(Api.fetchUser, action.payload.userId);

后

import { call, all } from "typed-redux-saga";
...
// user now has the correct type User
// NOTE: it's yield*, not yield
const user = yield* call(Api.fetchUser, action.payload.userId);
