你会考虑用它么？mini-obj

这是一个非常小的简单的oo用法封装

Install

npm install --save node-mini-obj

第一版

源码

module.exports = global.Class = function(name, src) { 
	src.constructor.prototype = src; 
	global[name] = src.constructor; 
}; 

用法

var $ = require('./index')

$('Person',{
    constructor: function(name) { 
        this.name = name;
    }, 
    say: function(){
        console.log('hello ' + this.name);
    }
})

var p = new Person('alfred sang');
p.say();

还是蛮舒服的吧？

第二版

这个版本主要增加了继承功能，具体用法如下

基本用法

没有构造函数的情况

$('Person1',{
	say: function(){
		console.log('hello ' + this.name);
	}
})

var p1 = new Person1();
p1.name = 'i5ting'
console.log(p1);
p1.say();

有构造函数的情况

var $ = require('./index')

$('Person',{
	constructor: function(name) { 
		this.name = name;
	}, 
	say: function(){
		console.log('hello ' + this.name);
	}
})

var p = new Person('alfred sang');
p.say();

测试1：plain object继承

var $ = require('./index')

$('Person',{
	constructor: function(name) { 
		console.log('---1----');
		this.name = name;
	}, 
	bbb:'bbb',
	hello:function(){
		console.log('hello');
	}
},
{
	constructor: function(name) { 
		console.log('---2----');
		this.name = name;
	
	}, 
	say: function(){
		console.log('hello ' + this.name);
		console.log(this.bbb);
	}
})

var p = new Person('alfred sang');
p.hello()
p.say();

测试2：使用已有对象完成继承

var $ = require('./index')

$('Base',{
	constructor: function(name) { 
		this.name = name;
	},
	hello:function(){
		console.log('hello');
	}
})

var base = new Base('a person');

$('Person',base,{
	constructor: function(name) { 
		this.name = name;
	}, 
	say: function(){
		console.log('hello ' + this.name);
		this.hello();
	}
})

var p = new Person('alfred sang');
p.say();
p.hello();

测试3：使用继承对象的原型方法

var $ = require('./index')

var Base = function(name){
	this.name = name;
}

Base.prototype.hello = function(){
	console.log('---Base.prototype.hello----');
}

var base = new Base('a person');

$('Person',base,{
	constructor: function(name) { 
		this.name = name;
	}, 
	say: function(){
		console.log('hello ' + this.name);
		this.hello();
	}
})

var p = new Person('alfred sang');
p.say();
