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 🙏

基于百度地图JavaScript GL版API封装的React组件库。如果想要使用旧版的2D地图的话,使用react-bmap。如果您对使用地图API完全陌生,建议使用这个库之前先了解百度地图JavaScript GL API,了解一些地图的基本概念,并申请开发者ak

文档示例

官方地址:http://huiyan.baidu.com/github/react-bmapgl/

备用地址:https://huiyan-fe.github.io/react-bmapgl/

开始使用

引入脚本

首先,需要在你的index.html模板页面头部加载百度地图JavaScript API代码,密钥可去百度地图开放平台官网申请

<script type="text/javascript" src="//api.map.baidu.com/api?type=webgl&v=1.0&ak=您的密钥"></script>

然后,使用npm方式安装react组件库,然后通过es模块加载

npm install react-bmapgl --save

Hello World

import React from 'react';
import ReactDOM from 'react-dom';
import {Map, Marker, NavigationControl, InfoWindow} from 'react-bmapgl';

class App extends React.Component {
    render() {
        return <Map center={{lng: 116.402544, lat: 39.928216}} zoom="11">
            <Marker position={{lng: 116.402544, lat: 39.928216}} />
            <NavigationControl /> 
            <InfoWindow position={{lng: 116.402544, lat: 39.928216}} text="内容" title="标题"/>
        </Map>
    }
}
ReactDOM.render(<App />, document.getElementById('container'));

获取map实例

如果你在业务中需要操作map对象,需要BMapGL.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}} />

如果你要开发Map的子组件,想要在子组件中获得map对象,可以直接在<Map>包裹的子组件中调用this.props.map即可。

function App() {
    return <Map>
        <MapComponent />
    </Map>
}

function MapComponent(props) {
    console.log(props.map);
}

异步加载与按需导入

异步加载

通常,如果您的业务场景总需要使用到地图,或者需要创建多个地图实例,我们会建议您在index.html模板中加入JSAPI的scirpt标签,因为这种方式对后续开发没有任何限制。
但是在某些业务场景下,可能并不一定会使用到地图,且用到的地图功能、组件也相对简单,我们也提供了MapApiLoaderHOC高阶组件,实现异步加载的方式。

class App extends React.Component {
  render() {
    return (
      <Map
        style={{ height: 450 }}
        center={new BMapGL.Point(116.404449, 39.914889)}
        zoom={12}
      />
    )
  }
}

export default MapApiLoaderHOC({ak: '您的密钥'})(App)

按需导入

常用的导入方法会直接把整个包导入进来

import { Map, Marker, MapvglView, MapvglLayer } from 'react-bmapgl'

如果希望引入的包体积小一点,所有组件都支持lodash风格进行按需导入

import Map from 'react-bmapgl/dist/Map'
import Marker from 'react-bmapgl/dist/Overlay/Marker'

本地开发

设计思想

React-BMapGL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的时候在地图上添加覆盖物,componentWillUnmount的时候移除覆盖物,componentDidUpdate的时候更新覆盖物,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-BMapGL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。

Typescript支持

本项目开发使用Typescript编写,声明文件为@types/bmapgl,如果需要修改,需要给DefinitelyTyped提PR。如果需要安装声明文件依赖,执行安装命令

npm install @types/bmapgl -D

常用命令

npm install         # 安装依赖

npm start           # 开始运行文档网站
npm run build:doc   # 文档网站构建编译

npm run build       # 组件库编译,输出 js 和 .d.ts 文件

npm publish         # 发布新npm包

发布npm包

修改package.json版本号后,直接执行npm publish
