模块化

commonjs

require / exports

exports

const Tool = {
  agent: {
    getActivityList: () => {
      console.log('activityList...');
    },
    updateActivityList: () => {
      console.log('updateActivityList...');
    },
  },
  serve: {
    sendMeg: (data) => {
      console.log(data);
    },
  },
};

exports.Tool = Tool;

require

const { Tool } = require('./commonjs exports');

Tool.serve.sendMeg('Hello');

console.log(Tool.agent.getActivityList);

ES6

export

const Tool = {
  agent: {
    getActivityList: () => {
      console.log('activityList...');
    },
    updateActivityList: () => {
      console.log('updateActivityList...');
    },
  },
  serve: {
    sendMeg: (data) => {
      console.log(data);
    },
  },
};

export default Tool;

require

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>ES6 Module</title>
  </head>

  <body>
    <script type="module">
      import Tool from './ES6 export.js';
      console.log(Tool);
    </script>
  </body>
</html>

浏览器还未很好的支持 ES6 Module

script 标签默认 type 属性为 javascript

在引入 module 时 需要告知浏览器这是 module
