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 🙏

Readme

xloader

Build Status Coverage Status

一个精致实用的Javascript模块加载器,可用于NodeJs环境和浏览器环境。

Useage

在HTML中引入加载器

<script src="${path-to-xloader}/dist/xloader.min.js"></script>

API

define(id, depends, factory) - 定义模块

/**
 * 定义模块
 * @param {String}    id      - 模块id
 * @param {Array}     depends - 依赖的模块
 * @param {NotArray}  factory - 模块构造器
 */
define(id, depends, factory)
define(id, depends)
define(id, factory)

require(ids, callback) - 加载模块

/**
 * 加载模块
 * @param {Array|String}  - 待加载的模块列表
 * @param {Function}      - 回调方法,可以省略
 * @return {Any}          - 同步加载时,会返回第一个已加载的模块,如果是异步加载返回`undefined`
 */
require(ids, callback)

xloader.config(name, value) - 配置加载器

loader.config(name)
loader.config(name, value)

一般用于配置aliasresolve规则

配置resolve

xloader.config('alias', {
  'util-request', 'util/request'
});

alias也可以是一个function

xloader.config('alias', function(id) {
  if (id.startsWith('ui-')) {
    return 'ui/' + id;
  }
});

配置resolve规则

xloader.config('resolve', function(id) {
  return '/assets/' + id + '.js';
});

xloader.new(namespace, [options]) -> Loader

定义一个新的loader

window.x = xloader.new('x', { autoloadAnonymous: true });

然后就可以使用x加载器了

x.define('util', ['exports'], function(exports) {
  exports.sum = function(a, b) {
    return a + b;
  };
});


x.require(['util'], function(util) {
  util.sum(1, 2).should.be.equal(3);
});

新构建的加载器支持以下API:

loader.define(id, depends, factory)

定义模块

loader.require(depends, callback)

加载模块

loader.hasDefine(id)

判断模块是否已加载

loader.undefine(id)

取消定义一个模块

loader.getModules()

取得加载器中所有的模块

loader.resolve(id)

解析模块远程地址

xloader.noConflict(deep)

默认情况下,加载器会占有xloader, define, require三个全局变量,如果有冲突时可以使用这个方法解决

window.x = xloader.noConflict();
define(...)     // 这个就是原来的define
x.define(...)   // 现在就可以使用x来定义和加载模块了
