【Javascript】OOP ‘终端' demo

stdlib.js

// 打包模块
module.exports = stdlib;

// 声明方法
stdlib.prototype.toString = toString;
stdlib.prototype.talk = talk;

// 声明变量
stdlib.prototype.className = null;

// 构造方法
function stdlib(name)
{
	this.className = ‘class: ‘ + name;
	// 获取IO流
	this.stdin = process.stdin;
	this.stdout = process.stdout;
};

// 方法
function toString() {
	return this.className;
};

function talk () {
	var interface = require(‘readline‘);
	var rl = interface.createInterface(this.stdin, this.stdout);
	rl.setPrompt(‘Nerds> ‘);
	rl.prompt();
	rl.on(‘line‘, function (cmd) {
		switch(cmd.trim()) {
			case ‘:q!‘:
				console.log(‘stream close!‘);
				process.exit(0);
				break;

			case ‘girlfriend‘:
				console.log(‘Dude,I bet you won`t :D‘);
				break;

			default:
				console.log(‘Say what? I might have heard `‘ + cmd.trim() + ‘`‘);
				break;

		}
		rl.prompt();
	}).on(‘close‘, function (cmd) {
		console.log(‘Enjoy js world, have nice day :D‘);
		process.exit(0);
	});
};

main.js

// 安装模块
var stdlib = require(‘./stdlib‘);
// 从模块中创建对象
var tsh = new stdlib(‘my stdlib‘);

console.log(tsh.toString());
tsh.talk();

node.js中采用 modules.exports = class 将某个类暴露供安装对应模块的文件使用

Lib.js:
module.exports = Lib;
function Lib() {}
...

UserFile.js 2:
var installModule = module(‘./Lib‘);
var instanceObject = installModule();
...

类似于java的打包和导入包

file 1:
package com;
public class Lib
{
.....
}

file 2:
import com.lib;
....
