【js模块化demo】CommonJS

CommonJs运行方式示例：CommonJS间接为前端模块，提供了后端脚本的模块化支持。 示例一：两个函数模块化成一个。 示例二：前端运行后端模块化脚本。 返回demo列表页

demo 代码分析

a.js

/**
 * @author: cuixiaohuan
 * Date: 15/12/7
 * Time: 下午8:09
 */
module.exports = function () {
    console.log('This is a.js');
};

b.js

/**
 * @author: cuixiaohuan
 * Date: 15/12/7
 * Time: 下午8:09
 */

var a = require('./a');
a();
console.log('This is b.js');

node生成运行模块和输出如下

cuihuan:js_module_CommomJs cuixiaohuan$ browserify b.js -o b_brow.js
cuihuan:js_module_CommomJs cuixiaohuan$ node b_brow.js
This is a.js
This is b.js

生成的b_brow.js

/**
 * @author: cuixiaohuan
 * Date: 15/12/7
 * Time: 下午8:09
 */
module.exports = function () {
    console.log('This is a.js');
};
},{}],2:[function(require,module,exports){
/**
 * @author: cuixiaohuan
 * Date: 15/12/7
 * Time: 下午8:09
 */

var a = require('./a');
a();
console.log('This is b.js');
},{"./a":1}]},{},[2]);

再来一个node的小栗子

# c.js
var uniq = require('uniq');
var nums = [ 5, 2, 1, 3, 2, 5, 4, 2, 0, 1 ];
console.log(uniq(nums));

# 生成node模块
$ browserify c.js > c_brew.js

#可以直接引入运行后端的函数
