javascript - es6 require parameter problem

Question

I haven’t found much specific usage of es6 require. Most of them are briefly introduced to load modules, such as
const es_namespace = require('./es');
But I have seen this use of resolve elsewhere. => require(['../pages/login/'], resolve), what does this require function mean? Is there any official documentation? Or go into details?

Answer 1

ES6 modularization uses import and export. For details, you can see "Understanding ECMAScript6" https://sagittarius-rev.gitbo...,
Chapter 13 of this book uses modules to encapsulate code. I think it is very well written. , very clear and concise.

The require you are talking about is a js library RequireJS,
Chinese document http://www.requirejs.cn/,
This tutorial is also good http://www.runoob.com/w3cnote...

Answer 2

Because require是require.js is a library, you can take a look at Ruan Yifeng’s introduction on how to use require.js

Answer 3

当 Node 遇到 require(X) 时，按下面的顺序处理。
（1）如果 X 是内置模块（比如 require('http'）) 
　　a. 返回该模块。 
　　b. 不再继续执行。
（2）如果 X 以 "./" 或者 "/" 或者 "../" 开头 
　　a. 根据 X 所在的父模块，确定 X 的绝对路径。 
　　b. 将 X 当成文件，依次查找下面文件，只要其中有一个存在，就返回该文件，不再继续执行。
X
X.js
X.json
X.node
　　c. 将 X 当成目录，依次查找下面文件，只要其中有一个存在，就返回该文件，不再继续执行。
X/package.json（main字段）
X/index.js
X/index.json
X/index.node
（3）如果 X 不带路径 
　　a. 根据 X 所在的父模块，确定 X 可能的安装目录。 
　　b. 依次在每个目录中，将 X 当成文件名或目录名加载。
（4） 抛出 "not found"

This is how require works.
['../pages/login/'] may load all files under "../pages/login/"
You can refer to require() source code interpretation
