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 🙏

开发指南

cityfun-gl SDK基于mapbox-gl的扩展库,不影响使用原生mapboxgl的功能。具体API参考mapboxgl官方文档

账号和获取密钥

通过平台账号密码获取

安装

cityfun-gl目前支持三种坐标系,wgs84地理坐标系(ESPG:4326),国家2000坐标系(EPSG:4490),web墨卡托投影坐标系(EPSG:3857)。不同坐标系统需要安装指定的SDK包;

  • EPSG:3857
<script src='./libs/cityfun/cityfun.min.css'></script>
<link href='./libs/cityfun/cityfun.min.js' rel='stylesheet' />

或,使用npm安装

npm i cityfun-gl
import cityfun from 'cityfun-gl'
  • EPSG:4326和EPSG:4490
<script src='./libs/cityfun/cityfun-4490.min.css'></script>
<link href='./libs/cityfun/cityfun-4490.min.js' rel='stylesheet' />

或,使用npm安装

npm i cityfun-gl-4490
import cityfun from 'cityfun-gl'

Hello World

使用cityfun-gl SDK创建一个简单的示例。

1、获取cfToken

通过平台账号密码获取

2、准备页面

根据HTML标准,每一份HTML文档都应该声明正确的文档类型,我们建议您使用最新的符合HTML5规范的文档声明:

<!DOCTYPE html>

您也可以根据需要选择其他类型的文档声明,这样浏览器会以标准的方式对页面进行渲染,保证页面最大的兼容性。我们不建议您使用quirks模式进行开发。

3、适应移动端页面展示

下面我们添加一个meta标签,以便使您的页面更好的在移动平台上展示。

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />  

4、设置容器样式

设置容器样式大小,使地图充满整个浏览器窗口:

<style type="text/css">  
    html{height:100%}    
    body{height:100%;margin:0px;padding:0px}    
    #container{height:100%}    
</style> 

4、引用cityfun-gl文件

<script src='./libs/cityfun/cityfun.min.css'></script>
<link href='./libs/cityfun/cityfun.min.js' rel='stylesheet' />

5、创建地图容器元素

地图需要一个HTML元素作为容器,这样才能展现到页面上。这里我们创建了一个div元素。

<div id="container"></div> 

6、设置地图配置信息

  • cfToken:使用平台账号获取的秘钥
  • ESPG:指定地图服务使用的坐标系统

注意:3857(web墨卡托投影坐标系);4490(cgcs2000);4326(wgs84坐标)

cityfun.setConfig({
  cfToken:
    "yAkqtubPdGtD61/l8DNLXhQrBCUcCeCQR9dzlyiMXHp3Qe9zsEtfy9k0YMAmXwOzx9p6BulJNYrLbejxUp6zYWpHhnKqZcgr3FjHGv8ybhHqLd4eWoGztA==",
  EPSG: 3857,
  geosite:"@cf"
});

7、创建地图实例

位于cityfun命名空间下的Map类表示地图,通过new操作符可以创建一个地图实例。

注意:创建地图对象时指定参数中,style必须是平台发布的矢量地图服务

cityfun.setConfig({
        cfToken:
          "yAkqtubPdGtD61/l8DNLXhQrBCUcCeCQR9dzlyiMXHp3Qe9zsEtfy9k0YMAmXwOzx9p6BulJNYrLbejxUp6zYWpHhnKqZcgr3FjHGv8ybhHqLd4eWoGztA==",
      });
         var map = new cityfun.Map({
  container: "container",
  center: [120.70044254024515, 31.301339366724918],
  zoom: 12,
  pitch: 60,
  style:"http://192.168.2.76/geocms/v1/cf/rest/services/MapService/VT/c772577d-6200-4469-8147-35d8009ab728",
});

8、监听地图加载完成事件

map.on("load", function() {});

9、定位地图中心点

map.on("load", function() {
    map.flyTo({center:[116.38, 39.90]});
});

10、完成实例

<!DOCTYPE html>
<html lang="zh-CN">
  <head>
    <meta charset="utf-8" />
    <title>地图展示</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <meta http-equiv="X-UA-Compatible" content="IE=Edge" />
    <style>
      body,
      html,
      #container {
        overflow: hidden;
        width: 100%;
        height: 100%;
        margin: 0;
      }
    </style>
    <link href="cityfun.min.css" rel="stylesheet" />
  </head>
  <body>
    <div id="container"></div>
    <script type="text/javascript" src="cityfun.min.js"></script>
    <script>
      cityfun.setConfig({
        cfToken:
          "your access token",
        EPSG: 3857,
      });
      cityfun.setConfig({
        cfToken:
          "yAkqtubPdGtD61/l8DNLXhQrBCUcCeCQR9dzlyiMXHp3Qe9zsEtfy9k0YMAmXwOzx9p6BulJNYrLbejxUp6zYWpHhnKqZcgr3FjHGv8ybhHqLd4eWoGztA==",
      });
         var map = new cityfun.Map({
        container: "container",
        center: [120.70044254024515, 31.301339366724918],
        zoom: 12,
        pitch: 60,
        style:
          "http://192.168.2.76/geocms/v1/cf/rest/services/MapService/VT/c772577d-6200-4469-8147-35d8009ab728",
      });
      map.on("load", function() {
        map.flyTo({center:[116.38, 39.90]});
      });
    </script>
  </body>
</html>
