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 🙏

Leaflet-CanvasMarker

在Canvas上绘制Marker,而不是每个marker插件一个dom节点,极大地提高了渲染效率。主要代码参考自 https://github.com/eJuke/Leaflet.Canvas-Markers ,不过此插件有些Bug,github国内不方便,作者也不维护了,所以在gitee上新建一个仓库进行维护与升级。 demo

npm下载

npm i @panzhiyue/leaflet-canvasmarker

使用

import {CanvasMarkerLayer} from "@panzhiyue/leaflet-canvasmarker"

示例

    // 创建图层
    var ciLayer = L.canvasMarkerLayer({
      collisionFlg: true
    }).addTo(map);

    var icon = L.icon({
      iconUrl: 'img/pothole.png',
      iconSize: [20, 18],
      iconAnchor: [10, 9]
    });
    // 定义Marker
    var markers = [];
    for (var i = 0; i < 100000; i++) {
      var marker = L.marker([58.5578 + Math.random() * 1.8, 29.0087 + Math.random() * 3.6], {
        icon: icon,
        zIndex: 2
      }).bindPopup("I Am " + i);
      markers.push(marker);
    }
    // 把marker添加到图层
    ciLayer.addLayers(markers);
    //定义事件
    ciLayer.addOnClickListener(function (e, data) {
      console.log(data)
    });
    ciLayer.addOnHoverListener(function (e, data) {
      console.log(data[0].data._leaflet_id)
    });
