返回`yield call`的类型

Question

我注意到yield call效果的结果在用作<{p>}时被输入为any

const data = yield call(f);

f是() => Promise<number>函数。

我错过了什么或是redux-saga类型限制吗？

检查this ongoing thread，tldr;这是一个打字稿限制

同时，您可以改用以下软件包：typed-redux-saga

之前

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);

之后

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);
