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 🙏

ind-map-transfer 转换地图jsApi

项目启动

node版本要求

启动 node >= 16 node8前端业务应用可以正常依赖

发布

yarn release
cnpm sync @indfnd/map-transfer

使用指南

  1. 安装依赖
npm install @indfnd/map-transfer
  1. 引入对应地图js后,加载转换api
import { initMapTransfer } from '@indfnd/map-transfer'

let p1 = getTxMapServiceSk() // 获取地图WebService服务密钥
let p2

// 获取地图key服务后,引入地图js
getTxMapKey().then(() => {
  p2 = addScript('https://map.qq.com/api/gljs?v=1.exp&libraries=service,geometry&key=' + txMapKey)

  Promise.all([p1, p2]).then(() => {
    // 加载地图转换
    initMapTransfer('tx2bd', {
      key: txMapKey,
      serviceSk: txMapServiceSk,
    })
    // console.log('加载地图转换成功', txMapKey, txMapServiceSk)
    console.log('加载地图转换成功', !!txMapKey, !!txMapServiceSk)
  })
})

initMapTransfer

initMapTransfer(transferType: String, options: Object)
/*
  transferType: 转换类型,可选值:
    - tx2bd(将腾讯的TMap转换为百度的Map)
  options: 配置项
    - key: '', // 地图的key,所有地图应该都需要申请个key
    - serviceSk: '', // 腾讯地图WebService可能还有个WebService的sk
*/

api转换思路

  1. 参考地图api的类参考,封装对应的类
  2. 在各个类中保留引入js地图的对应实例,以供类之间互相调用的需要
  3. 坐标系转换统一在 Point 类中,转换两个地图坐标点时实现
  4. 实现大部分场景,复杂场景不实现,如自定义覆盖物
