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 🙏

api 使用

  • 工具篇
import {createViewer,setMaxPitch,removeEntityByName,window2Proj} from 'jas-cesium-libs'

// 快速创建一个无官方控件的地球
const viewer = createViewer("{{div-id}}");

// 设置镜头最大仰角
setMaxPitch(viewer, -0.3);

// 根据实体名 删除viewer.entities 中的元素
// 注 :之后修改为 EntityCollection 替换 Viewer 类型
removeEntityByName(viewer,"{{entity-name}}");

// 屏幕点转化为投影坐标
const point = {x:1,y:2};
window2Proj(viewer,point);
  • 标记功能
import {createViewer, Marker} from 'jas-cesium-libs'

// 快速创建一个无官方控件的地球
const viewer = createViewer("{{div-id}}");

// 创建标记功能
const marker = new Marker(viewer); // or : new Marker(viewer,entity=>complete(entity));

// 修改样式
marker.style.point_Color = "#ffff00";

// 开始标记 可重复使用
marker.start('Point'); // or : .start('Line');  .start('Polygon');

// 结束标记
marker.stop();
  • 镜像
import {createViewer, Mirror} from 'jas-cesium-libs'

// 快速创建一个无官方控件的地球
const viewer_master = createViewer("{{div-id-master}}");
const viewer_slave = createViewer("{{div-id-slave}}");

// 创建镜像
const mirror = new Mirror(viewer_master,viewer_slave); // or : new Mirror("{{div-id-master}}","{{div-id-slave}}");

// 获取左右两个viewer
const {master1,slave1} = this.getViewers();
