perfmjs

high performance javascript framework v3.x

perfmjs v3.x Features:

开发目的:对mobile更友好,对开发人员更友好,为未来而设计。

3条军规:

  1. 从业务消费点出发做技术

  2. 兼顾安全高可靠与高性能

  3. 代码“简约易读易改”

v3.0.0新特性:

  1. 向上兼容ES6,H5

  2. perfmjs-node v3.x

  3. 精简代码(删除无用的模块等)

  4. 一站式开发工具,文档齐全,可加密打包

  5. 统一捕获错误堆栈

  6. 充分利用现代浏览器的新特性(如并发)

  7. 可定制打包多个版本(mini版、ie6版polyfill、h5版等)

perfmjs V2.x Features

fast by default:高效,易用,易读

核心库(core.js)压缩后只有32k+,还可以优化至更小

实现了浏览器端的AMD(Asynchronous Module Definition)异步模块定义规范,功能类似require.js, 但比require.js更轻量

实现了异步编程模块(Promises/A+)规范

原生态支持面向对象(object-oriented)功能

更高效的插件开发机制

更高效的js和css资源加载功能(底层功能由head.js提供)

更高效的js和css资源文件版本号管理功能

支持高效的数组操作,事件代理,AOP, 状态机, 日志等功能

可测试性,通过了jasmine库的测试

支持所有的主流浏览器,包括:ie5.5+, firefox, chrome, safari, etc

Nodejs版的perfmjs框架请移步:https://github.com/perfmjs/perfmjs-node

可选功能:

jQuery/zepto.js是该框架的可选部分。DOM操作,AJAX,CSS等功能可以使用jQuery及类似框架提供,perfmjs框架在这些功能上不重复发明轮子!

代码质量与构建

WebStorm, SlikSvn(svn命令行客户端), Node.js开发环境, gulp-uglify + gulp-jshint + gulp-jsdoc + 公司的代码规范文档, Jasmine

TODO:

增加资源文件自已更新缓存的功能(不需使用版本号)

去掉namespace(保留base的单例模式),拥抱angular2的趋势

How to use(for v2.x)

foo.js

define('foo', ['base'], function(base) {
    base("foo", {
        init: function(initParam) {
            return this;
        },
        sayHello: function(name) {
            return 'hi- ' + name;
        },
        foo: function() {
            return 'foo!';
        },
        end: 0
    });
    base.foo.defaults = {
        end: 0
    };
    return base.foo;
});

bar.js, 继承于foo.js

define('bar', function(require) {
    var base = require('base');
    require('foo');
    base("foo.bar", {
        init: function(initParam) {
            return this;
        },
        sayHello: function(name) {
            var superName = this._super('sayHello', name);
            return 'call super:' + superName + ', call self: hello- '
                        + name + "/foo:" + this.foo();
        },
        end: 0
    });
    base.bar.defaults = {
        end: 0
    };
    return base.bar;
});
