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 🙏

amap-jsapi-loader

amap-jsapi-loader 是高德开放平台官网提供的地图 JSAPI 的加载器,可帮助开发者快速定位、有效避免加载引用地图 JSAPI 各种错误用法。

该加载器具有以下特性:

  • 支持以 普通JS 和 npm包 两种方式使用;
  • 有效避免错误异步加载导致的 JSAPI 资源加载不完整问题;
  • 对于加载混用多个版本 JSAPI 的错误用法给予报错处理;
  • 对于不合法加载引用 JSAPI 给予报错处理;
  • 支持指定 JSAPI 版本;
  • 支持插件加载;
  • 允许多次执行加载操作,网络资源不会重复请求,便于大型工程模块管理;

USAGE

AMapLoader.load方法参数说明

AMapLoader.load({
    "key": "",              // 申请好的Web端开发者Key,首次调用 load 时必填
    "version": "2.0",   // 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15
    "plugins": []           // 需要使用的的插件列表,如比例尺'AMap.Scale'等
    "AMapUI": {             // 是否加载 AMapUI,缺省不加载
        "version": '1.1',   // AMapUI 缺省 1.1
        "plugins":[],       // 需要加载的 AMapUI ui插件
    },
    "Loca":{                // 是否加载 Loca, 缺省不加载
        "version": '1.3.2'  // Loca 版本,缺省 1.3.2
    },
}).then(()=>{
    window.AMap.xx;
    window.AMapUI.xx;
    window.Loca.xx
});

AMapUI

AMapUI 用法和官网有一点点区别。通过 AMapUI.xx 来获取组件

AMapLoader.load({
    key: '',//首次load必填
    version: '2.0',
    AMapUI: {
        version: '1.1',
        plugins: ['overlay/SimpleMarker'],
    }
}).then((AMap) => {
    map = new AMap.Map('container');

    // !!! 通过 AMap.SimpleMarker 获取组件
    new AMapUI.SimpleMarker({
        //前景文字
        iconLabel: 'A',
        //图标主题
        iconTheme: 'default',
        //背景图标样式
        iconStyle: 'red',
        map: map,
        position: map.getCenter()
    });
}).catch((e) => {
    console.error(e);
});

使用

以普通 JS 方式使用 Loader

尚未发布在线Loader,可将 dist/index.js 复制到项目下

<script src="../dist/index.js"></script>
<script>
    AMapLoader.load({
        key:'',//首次load必填
        version:'2.0',
        plugins:['AMap.Scale']
    }).then((AMap)=>{
        map = new AMap.Map('container');
        map.addControl(new AMap.Scale())
    }).catch((e)=>{
        console.error(e);
    });   
</script>

以 NPM 包方式使用 Loader

安装

tnpm i @alife/amap-jsapi-loader --save-dev

使用

import AMapLoader from '@alife/amap-jsapi-loader';

AMapLoader.load().then((AMap)=>{
    map = new AMap.Map('container');
}).catch(e=>{
    console.log(e);
})
