JSPM 初体验

发表于

终于得空，体验一把 JSPM



jspm is a package manager for the SystemJS universal module loader, built on top of the dynamic ES6 module loader



 


1. 安装


npm install jspm -g

2. 创建项目


npm install jspm –save-dev
jspm init

3. 安装包


jspm install npm:lodash-node
jspm install github:components/jquery
jspm install jquery
jspm install myname=npm:underscore

4. 编码


./lib/bootstrap.js


import $ from ‘jquery’;
export function bootstrap() {
    // bootstrap code here
    console.log(‘bootstrap function’);
    console.log($(‘body’).length);
};

./lib/bootstrap2.js


export function bootstrap2() {
    // bootstrap code here
    console.log(‘bootstrap2 function’);
}

export function bootstrap3() {
    // bootstrap code here
    console.log(‘bootstrap3 function’);
}

./lib/main.js


import {bootstrap} from ‘./bootstrap.js’;
import {bootstrap2} from ‘./bootstrap2.js’;
import {bootstrap3} from ‘./bootstrap2.js’;
bootstrap();
bootstrap2();
bootstrap3()

./text.html


<!doctype html>
<script src=”jspm_packages/system.js”></script>
<script src=”config.js”></script>
<script>
    System.import(‘./lib/main.js’);
</script>

5. 运行


随便丢到一个 web 服务器即可。记得修改 ./config.js 中的 baseURL


6. Bundle for projection


我也不知道干嘛用的，运行下就重新编译了。还不知道怎么像 grunt 一样的 watch


jspm bundle lib/main –inject

萌萌哒，才喜欢 grunt 半年多，希望他能长久。
