export与export default均可用于导出常量、函数、文件、模块
在一个文件或模块中,export、import可以有多个,export default仅有一个
使用export default命令,为模块指定默认输出,这样就不需要知道所要加载模块的变量名
Node里面的模块系统遵循的是CommonJS规范:CommonJS定义的模块分为: 模块标识(module)、模块定义(exports) 、模块引用(require)
require方能看到的只有module.exports这个对象,它是看不到exports对象的,而我们在编写模块时用到的exports对象只是对module.exports的引用 Node.js模块里exports与module.exports的区别? - 知乎
//demo1.js export const str = 'hello world' export function f(a){ return a+1 }
//demo2.js import { str, f } from 'demo1' //也可以分开写两次,导入的时候带花括号
//demo1.js export default const str = 'hello world'
//demo2.js import str from 'demo1' //导入的时候没有花括号
