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 🙏

React-BMap

npm version Package Quality

基于百度地图JavaScript Api封装的React组件库,使用这个库最好需要先了解React百度地图JavaScript Api

React-BMap只是利用了React组件的生命周期,来调用对应的百度地图JavaScript Api的方法,比如在componentDidMount和componentDidUpdate的时候在地图上添加覆盖物,componentWillUnmount的时候移除覆盖物,React对应的render渲染函数模块返回的是null。所以这里面地图相关的dom并不是react渲染的,真正创建地图之类的还是使用百度地图JavaScript Api,React-BMap只是利用了React组件的写法来封装百度地图JavaScript Api,使我们在使用React的时候能更方便的使用百度地图JavaScript Api。

3D地图版本

该组件库是针对2D版本地图的React组件库,如果想使用新版本的3D地图,请使用React-BMapGL。新的GL版地图支持无级缩放、地图倾斜、旋转等强大的功能,并且能更好的发挥MapVGL炫酷的可视化效果。
PS:由于3D地图基于WebGL开发,部分功能与2D版体验可能有差别,如果您的设备不支持WebGL,或者更追求稳定性,依然可以选择本组件库。

示例

可查看示例文件夹下的示例使用示例代码,示例效果可访问预览地址

安装使用

页面头部需加载百度地图JavaScript Api代码

<script type="text/javascript" src="http://api.map.baidu.com/api?v=3.0&ak=您的密钥"></script>

密钥可去百度地图开放平台官网申请

推荐使用npm方式安装使用,然后通过es6模块加载

npm install react-bmap

支持UMD规范的打包库

<script src="http://huiyan-fe.github.io/react-bmap/dist/react-bmap.min.js"></script>

获取 BMap.Map 实例

如果你使用 BMapLib,需要 BMap.Map 实例的话,可以通过 <Map> 组件实例的 map 属性访问到它。

<Map ref={ref => {this.map = ref.map}} />
