Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

seal-module

其他类的基础模块,其他的类需要继承此类

* 提供了类的静态属性和原型的扩展
* 提供了事件订阅和发布功能
* 提供了国际化功能

DEMO

用你的自定义类继承这个模块类似于这样extend(Pen, SealModule);后,就可使用SealModule的方法。基础的使用代码如下

var hasProp = {}.hasOwnProperty;
var extend = function(child, parent) {
    for (var key in parent) {
        if (hasProp.call(parent, key)) child[key] = parent[key];
    }
    function ctor() {
        this.constructor = child;
    }
    ctor.prototype = parent.prototype;
    child.prototype = new ctor();
    child.__super__ = parent.prototype;
    return child;
}
function Knife() {}                                         // 你自己的类
Knife.pluginName = "Knife";                                 // 必须提供一个插件名称
function Pen() {
    Pen.__super__.constructor.apply(this, arguments);       // 调用SealModule构造方法初始化
}
extend(Pen, SealModule);                                    // 继承SealModule
Pen.connect(Knife);                                         // 给Pen添加一个插件类Knife
var p = new Pen;                                            // 实例化你的对象
// do something
// p.xxx

API:

SealModule.extend

静态方法extend可以让Pen扩展它的静态方法,用法如下。

var extendMixin = {
    color: "gray",
    type: "2b"
};
Pen.extend(extendMixin);
Pen.color;      // gray

SealModule.include

静态方法include可以让Pen扩展它的原型方法,用法如下。

var prototypeMixin = {
    price: 3
};
Pen.include(prototypeMixin);
var p = new Pen;
p.price;        // 3

SealModule.connect

静态方法connect可以给Pen添加一个或多个依赖的插件或类,用法如下。

如果给Pen添加了一个插件Knife后,当new一个Pen实例为p,在构造函数中它会自动创建Knife实例,暴露在p实例的属性中 p.Knife

function Knife() {

}
Knife.prototype._init = function() {
    console.log('Knife init');
}
Knife.pluginName = "Knife";
Pen.connect(Knife);
var p = new Pen();
p.Knife;            // 一个Knife的实例

object.on

on 是基于jquery的事件监听方法

一个继承了SealModule对象的实例拥有一个on方法,给当前对象实例添加一个事件监听。

var p = new Pen;
p.on('sealmodule.on', function(e, date) {
    // do someting
    name = date.name;
});

object.one

one 是基于jquery的事件监听方法

一个继承了SealModule对象的实例拥有一个one方法,给当前对象实例添加一个事件监听,这个事件只执行一次。

var p = new Pen;
p.one('sealmodule.on', function(e, date) {
    // do someting
    name = date.name;
});

object.off

off 是基于jquery的事件监听方法

一个继承了SealModule对象的实例拥有一个off方法,给当前对象实例解绑事件监听。

var p = new Pen;
p.off('sealmodule.on');

object.trigger

trigger 是基于jquery的事件监听方法

一个继承了SealModule对象的实例拥有一个trigger方法,触发一个事件。

var p = new Pen;
p.trigger('sealmodule.on', {name: 'tudousi'});

_t

对字符串进行国际化,可以只传递一个字符串进行简单的翻译,也可以传入参入对 %s 占位符进行替换,用法如下。

关于国际化的配置参见文件 i18n

// 用法1,参数只是一个字符串
// 'Hello': "你好"
function Pen() {
    Pen.__super__.constructor.apply(this, arguments);
}
extend(Pen, SealModule);
Pen.prototype.translate = function() {
    console.log(this._t('Hello'));
}

// 用法2,可以用参数替换占位符 %s
// "Message": "你有 %s 条消息,未读 %s 条消息"
function Pen() {
    Pen.__super__.constructor.apply(this, arguments);
}
extend(Pen, SealModule);
Pen.prototype.translate = function() {
    console.log(this._t('Message', 100, 32));
}

// 用法3,可以使用嵌套对象
/*
"info": {
    "name": "jiangzhu"
}
*/
function Pen() {
    Pen.__super__.constructor.apply(this, arguments);
}
extend(Pen, SealModule);
Pen.prototype.translate = function() {
    console.log(this._t('info.name'));
}

// 用法4,可以直接使用静态方法进行翻译
Pen._t('Hello');
