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 🙏

QQ Maps Components for Angular

NPM version Ci

Demo

1、安装

npm install angular-qq-maps --save

AqmModule 模块导入到你项目中。

import { AqmModule } from 'angular-qq-maps';

@NgModule({
  imports: [
    BrowserModule,
    AqmModule.forRoot({
      apiKey: '' // app key为必选项
    })
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule { }

2、使用

地图组件

<aqm-map #map [options]="options" (ready)="onReady($event)" style="height: 300px;"></aqm-map>

街景组件

<aqm-panorama #map [options]="options" (ready)="onReady($event)" style="height: 500px;"></aqm-panorama>

默认自动异步加载 js 类库,所以只需要在 NgModule 提供 api key 就可以立即使用了。 options 等同腾讯地图 new qq.maps.Map(mapContainer, options)

关于事件注意点(很重要,请认真阅读)

我精力有限,而如果真要以Angular的角度去开发腾讯地图工作量非常大,而且官网也并无提供一份良好的Typescript接口定义,所以放弃过度性封装。正因为如此,所以您在注册事件的时候还是要认真一点。

腾讯地图除绝大部分所需要的事件都是依赖于 qq.maps.event 对象的创建和删除动作,Angular是一种单页开发模式,对资源的创建与销毁是非常重要的。如果你在开发腾讯地图的时候突然发现被污染了,那说明你的并没有正确的销毁。

因此,我建议,当你需要注册一个地图的 click 事件时:

//添加监听事件
qq.maps.event.addListener(this.map, 'click', (event: any) => {
  // doing
  this.zone.run(() => {
    // 对于需要Angular监听的变量而放在 zone 里面,可以确保页面渲染。
    this.status = `click ${+new Date}`;
  });
});

与之相对应,一定要在 ngOnDestroy 对事件的销毁:

ngOnDestroy(): void {
  ['click'].forEach(eventName => {
    qq.maps.event.clearListeners(this.map, eventName);
  });
}

当然,这里还有一些关于覆盖物相关里面涉及的事件,也一并做相应的销毁处理。

很抱歉,如果你在使用 angular-qq-maps 的时候请认真阅读
