導入如何在引用模塊的導出名稱時使用節點模塊？

Question

當一個index.js做下面的導入時，'redux'是指什麼？我試着在node_modules的redux包的src目錄中查找，但找不到任何導出'redux'的東西。這個名稱空間是否通過package.json文件中的依賴關係提供？

import { createStore } from 'redux' 

Answer 1

它指的是redux模塊。 CreateStore它是模塊的一部分。你應該閱讀文檔https://github.com/reactjs/redux 在ES6語法，你可以這樣只寫'使用這些模板

import defaultMember from "module-name"; 
    import * as name from "module-name"; 
    import { member } from "module-name"; 
    import { member as alias } from "module-name"; 
    import { member1 , member2 } from "module-name"; 
    import { member1 , member2 as alias2 , [...] } from "module-name"; 
    import defaultMember, { member [ , [...] ] } from "module-name"; 
    import defaultMember, * as name from "module-name"; 
    import "module-name";
