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 🙏

安装

npm install vue-openlayers-plugin
# 或
yarn add vue-openlayers-plugin
# 或
pnpm add vue-openlayers-plugin

快速开始

全局注册

import { createApp } from 'vue'
import VueOpenLayersPlugin from 'vue-openlayers-plugin'
import 'vue-openlayers-plugin/style'

const app = createApp(App)
app.use(VueOpenLayersPlugin)
app.mount('#app')

如果使用移动端组件(MobileMapMobileLegend 等),请额外安装并注册 Vant:

npm install vant
# 或
yarn add vant
# 或
pnpm add vant
import { createApp } from 'vue'
import Vant from 'vant'
import 'vant/lib/index.css'
import VueOpenLayersPlugin from 'vue-openlayers-plugin'

const app = createApp(App)
app.use(Vant)
app.use(VueOpenLayersPlugin)
app.mount('#app')

按需引入

import { CustomOpenlayer, CustomDialog, SvgIcon, MobileMap } from 'vue-openlayers-plugin'
import 'vue-openlayers-plugin/style'

// 在组件中使用
export default {
  components: {
    CustomOpenlayer,
    CustomDialog,
    SvgIcon,
    MobileMap
  }
}

基础使用

<template>
  <div class="map-container">
    <CustomOpenlayer
      :center="[116.397428, 39.90923]"
      :zoom="10"
      :show-layer-panel="true"
      :show-measurement-tools="true"
      :show-drawing-tools="true"
      style="width: 100%; height: 500px;"
      @map-ready="onMapReady"
      @feature-selected="onFeatureSelected"
    />
  </div>
</template>

<script setup lang="ts">
import { CustomOpenlayer } from 'vue-openlayers-plugin'

const onMapReady = (map: unknown) => {
  console.log('地图已准备就绪', map)
}

const onFeatureSelected = (feature: any) => {
  console.log('选中要素', feature)
}
</script>

<style >
.map-container {
  width: 100%;
  height: 500px;
  border: 1px solid #ddd;
  border-radius: 4px;
}
</style>

移动端使用(MobileMap)

MobileMap 内置了移动端常用 UI(搜索、图层面板、图例入口等),通过 Props 控制显示:

<template>
  <div class="mobile-page">
    <MobileMap
      :config="mapConfig"
      :show-search="true"
      :show-layer-panel="true"
      :show-legend="true"
      @map-ready="onMapReady"
    >
      <MobileBasemapSwitcher
        class="basemap-switcher"
        :base-layers="mapConfig.baseLayers"
      />
    </MobileMap>
  </div>
</template>

<script setup lang="ts">
import { MobileBasemapSwitcher, MobileMap } from 'vue-openlayers-plugin'
import type { MapConfig } from 'vue-openlayers-plugin'

const mapConfig: MapConfig = {
  center: [116.397428, 39.90923],
  zoom: 10,
  baseLayers: [
    {
      id: 'osm',
      name: 'OpenStreetMap',
      type: 'osm',
      visible: true,
      isBasemap: true,
      legend: {
        title: '开源地图',
        items: [
          { label: '道路', color: '#ffffff' },
          { label: '建筑', color: '#f2f2f2' }
        ]
      }
    },
    {
      id: 'arcgis_imagery',
      name: 'ArcGIS影像',
      type: 'xyz',
      url: 'https://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}',
      visible: false,
      isBasemap: true,
      legend: {
        title: '全球影像',
        items: [{ label: '高清卫星图', color: '#8B4513' }]
      }
    }
  ],
  overlayLayers: []
}

const onMapReady = (map: unknown) => {
  console.log('移动端地图已准备就绪', map)
}
</script>

<style>
.mobile-page {
  position: relative;
  width: 100%;
  height: 100vh;
  overflow: hidden;
}
.basemap-switcher {
  position: absolute;
  right: 12px;
  bottom: 160px;
  z-index: 230;
}
</style>
