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 🙏

最新进度

2020.02.06: v3.0.0

  • NEW:

    • 支持 AMapUI 库,可通过 AmapUILoaderService 服务加载使用,部分 UI 组件也封装成了指令,如:ui-awesome-marker
    • 提供加载插件服务:AmapPluginLoaderService,部分常用插件已封装成了指令,如:amap-tool-bar
  • BREAKING CHANGES:

    • 重写了整体的封装架构,不再使用 Promise 封装,全部使用 Observable
    • @Output 事件命名统一调整为: 包含na前缀
    • 不再提供 Getter 和 Setter 的 Wrapper,建议直接调用 amap 原生对象的方法
    • 移除 amap 相关的类型定义,引入 @types/amap-js-api

安装

npm install -S ngx-amap
npm install -D @types/amap-js-api
# 地图插件类型定义可按需安装:
npm install -D @types/amap-js-api-tool-bar
npm install -D @types/amap-js-api-heatmap
npm install -D @types/amap-js-api-autocomplete
npm install -D @types/amap-js-api-place-search
npm install -D @types/amap-js-api-driving
npm install -D @types/amap-js-api-transfer
# ...

使用

  1. import NgxAmapModule

    • Example:
      import { NgxAmapModule } from 'ngx-amap';
      
      @NgModule({
        imports: [
          ...,
          NgxAmapModule.forRoot({
            apiKey: '你申请的key'
          })
        ],
        ...
      })
      export class AppModule { }
  2. 使用 ngx-amap 组件时必须给定高度.

    • 简单示例:

      • html:
      <ngx-amap class="demo-map"></ngx-amap>
      • css:
      .demo-map {
        height: 400px;
      }
  3. 可以配合使用其他指令和组件。例如 amap-marker 可以在地图中画覆盖物:点标记。

    • 简单示例:

      • html:
      <ngx-amap class="demo-map" [center]="[116.397428, 39.90923]">
        <amap-marker [position]="[116.397428, 39.90923]" (markerClick)="onMarkerClick($event)"></amap-marker>
      </ngx-amap>
  4. 加入地图控件的方法也很简单,例如:amap-tool-bar

    • 简单示例:

      • html:
      <ngx-amap class="demo-map">
        <amap-tool-bar></amap-tool-bar>
      </ngx-amap>
  5. 由于采用了懒加载高德 JS 库,所以如果需要直接使用全局 AMap 对象的方法,需要等加载完成后使用。

    • 可以在组件 <ngx-amap> (naReady) 事件之后使用 AMap
    • 也可以使用 AMapLoaderServiceload 方法
    import { AMapLoaderService } from  'ngx-amap';
    
    @Component({
      ...
    })
    export class MyComponent implements OnInit {
      constructor(private loader: AMapLoaderService) {}
    
      ngOnInit() {
        this.loader.load().subscribe(() => {
          // 高德 JS SDK 加载完毕
          const dis = AMap.GeometryUtil.distance([123, 456], [123, 456]);
          console.log(dis: ${dis});
        })
      }
    }

更多用法和事件,请参看演示和文档。

配置

我们可以通过NgxAmapModuleforRoot()方法设置ngx-amap。它可以接受以下参数传入:

{
  apiKey: string;   // 高德地图的开发者license key
  apiVersion?: string;  // [可选], api 版本, 默认是 '1.4.15'
  uiVersion?: string;   // [可选], ui 库版本, 默认是 '1.0.11'
  protocol?: 'http' | 'https'; // [可选], api 路径协议类型
  debug?: boolean; // [可选], 是否开启调试模式
  debugTags?: string; // [可选], 开启调试的 TAG, '*' 为全部
}

加载插件

部分常用插件如: AMap.ToolBar 已封装成指令,可直接使用。

插件可通过服务:AmapPluginLoaderService 加载后使用。若插件需要 mapObject,可配合 ngx-amap(naReady) 事件一起使用。

查看示例

加载UI库

部分常用 UI 库如: AMapUI.SimpleMarker 已封装成指令,可直接使用。

UI 库可通过服务:AmapUILoaderService 加载后使用。若 UI 需要使用 mapObject,可配合 ngx-amap(naReady) 事件一起使用。
