我有一个上下文 API：

import React, { createContext, useState } from "react";

const UserContext = createContext();

const UserContextProvider = (props) => {
    const [userInfo, setUserInfo] = useState({});

    return (
        <UserContext.Provider value={{ userInfo, setUserInfo }}>
            {props.children}
        </UserContext.Provider>
    )
};

export { UserContextProvider, UserContext };

并在 App.js 中使用它：

<UserContextProvider>
  // Router,...
</UserContextProvider>

好吧，我将在组件中使用上下文 API，例如服务：

import { UserContext } from "...";

function UserService() {
    const { userInfo, setUserInfo } = useContext(UserContext);


    const updateUserInfo = (newUserInfo) => {
         setUserInfo(newUserInfo); // for example: {name:'x'}
    }

    return null; …

我制作了一个带角度6的库。构建库时，的脚本部分package.json将被删除。我该如何防止呢？（库建立后我需要脚本部分）

如何建造： ng build --prod MyLibraryName

Stimulsoft 报告：

如何在 asp.net core 中使用其变量和参数呈现报告并以角度显示？

角度：

viewer: any = new Stimulsoft.Viewer.StiViewer(null, 'StiViewer', false);
report: any = new Stimulsoft.Report.StiReport();

this.report.load("the report get from my api"); // ???

this.viewer.report = this.report;
this.viewer.renderHtml('viewer');

Asp.net核心：

public async Task<IActionResult> GetReport()
{
    StiReport report = new StiReport();
    report.Load(@"D:\myreport.mrt"); // for example load it from local

    // set parameters and variables here.it's ok

    // this return does not prepare report for showing in angular.It uses for view of action
    return StiNetCoreViewer.GetReportResult(this, report);
}

如何以这种方法准备报告以正确显示角度？

我有一个使用的自定义挂钩useReducer。

function useMyCustomHook() {
   const [state, dispatch] = useReducer(EntityReducer, initialState);

   // console.log(state); // 1- state is up to date here

   const customDispatch = (action) => {
       dispatch({ ...action }); // first call EntityReducer by action.type

       //2- I use state and dispatch here(for example:use state for call an api, then dispatch response)
       // but the state is previous not new state?

       switch (action.type) {
           case "something":
               // use dispatch and state here                     
               return state;
       }
   }

   return [state, customDispatch]; …
