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 🙏

ol3-echarts

v3.0.2

Published

a openlayers extension to echarts

Readme

ol3-echarts(Legacy)

面向旧版 openlayers 3 / 4 的 Apache ECharts 桥接包。

新项目请使用 ol-echarts,它面向模块化 ol 7–10,并提供更完整的 TypeScript 类型与维护保障。

安装

pnpm add ol3-echarts openlayers echarts
import ol from 'openlayers';
import EChartsLayer from 'ol3-echarts';

const map = new ol.Map({
  target: 'map',
  layers: [
    new ol.layer.Tile({
      source: new ol.source.OSM(),
    }),
  ],
  view: new ol.View({
    projection: 'EPSG:4326',
    center: [108.18, 34.34],
    zoom: 5,
  }),
});

const layer = new EChartsLayer(option, {
  hideOnMoving: true,
  hideOffscreenLabels: true,
});

layer.appendTo(map);

CDN

锁定版本可避免 CDN 缓存导致不可重复的构建:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/ol.css" />
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/ol.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/echarts.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/ol3Echarts.js"></script>

全局构造器为 ol3Echarts

维护状态

  • 仅接受 OpenLayers 3 / 4 范围内的兼容修复;
  • 主动开发、现代构建链与新 OpenLayers 版本支持都在 ol-echarts
  • 通用 API、坐标锚点和越界标签说明见项目文档

生命周期结束时调用 layer.remove(),释放 ECharts、DOM 和地图监听器。
