xng-cjs

把 JavaScript 模块从CommonJs 规范转化为 ES6 规范.

快速开始

全局安装:

npm install xng-cjs -g

本地调试:

cnpm i

node bin/xng-cjs [文件或者文件名]

每次更新后npm run build

全局命令使用:

xng-cjs [文件或者文件名]
如 xng-cjs src | xng-cjs src/fileName.js

暂时不支持的转换格式

const a = require('a').default;
const {a, b} = require('a');
const a, {b, c} = require('a');

const obj = {};
let a = {
    a,
  ...obj
}
module.exports = a

转换效果

const a = require('./a'); -> import a from './a';


module.exports = {a:1}; -> exports defualt {a:1};
