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 🙏

草果地图主题样式 — 矢量主题构造 + 暗/亮双套配色 + CSS 变量体系

Readme

@caoguo/theme

草果地图主题样式包 — 矢量主题构造 + 暗/亮双套配色 + CSS 变量体系

npm version license

安装

npm install @caoguo/theme
# 或
pnpm add @caoguo/theme

maplibre-gl@^4.7.1 是 peerDependency,请确保已安装。

功能

  • 提供两套矢量主题:caoguo-dark(指挥中心/大屏)和 caoguo-light(日常浏览)。
  • 通过 buildStyle() 构造完整 MapLibre Style Spec(含地形、水系、道路、行政边界、注记)。
  • 支持中文字体覆盖(Noto Sans SC / 思源黑体)。
  • 提供 CSS 变量主题系统(data-theme="..."),与 VitePress 等 SPA 框架天然兼容。
  • 主题构造为纯函数,可在 Node 环境测试、可在浏览器端直接使用。
  • buildStyle 始终保证输出含 glyphs(style 自身未声明且无 opts.glyphs 时回退 DEFAULT_GLYPHS),避免 symbol 层中文注记渲染失败。

内置图层清单(每套主题 15 层)

| 图层 id | 类型 | source-layer | 说明 | |---------|------|--------------|------| | background | background | — | 底色铺底(始终可见) | | water | fill | water | 水系面 | | landuse | fill | landuse | 土地利用 | | landcover | fill | landcover | 地表覆盖 | | road-minor | line | roads(class=minor) | 次干道,minzoom=12 | | road-major | line | roads(primary/secondary/tertiary/motorway) | 主干道,宽度随缩放插值 | | road-label | symbol | roads(线注记) | 道路名,minzoom=13 | | boundary | line | boundaries | 行政边界(虚线) | | waterway | line | waterway | 河流/水渠线 | | rail | line | railway | 铁路(虚线) | | park | fill | park | 绿地/公园 | | building | fill | building | 建筑面,minzoom=13 | | building-extrusion | fill-extrusion | building | 建筑 3D 挤出(基于 height/min_height),minzoom=15 | | place-label-major | symbol | places(scalerank≤3) | 主要地名(粗体) | | place-label-minor | symbol | places(scalerank>3) | 次要地名,minzoom=8 |

注记分级依据矢量源的 scalerank 字段;若你的瓦片源无该字段,可改用 registerTheme 自定义主题。

缩放层级覆盖(PRD 验收「3-18 无断裂」)

包内测试对 themeNames 每套主题在 zoom 3..18 做静态校验:background/water 全程可见,z≥8 至少有主干道或注记之一,z≥13 出现建筑层。真机渲染断档仍需以实际瓦片源在浏览器验收。

快速开始

主题切换 composable(useTheme)

useTheme() 封装 injectTheme 并监听 cg:themechange,适合在 VitePress enhanceApp / 组件内使用,返回响应式 themesetTheme/toggle。当任意处(含地图实例)切换主题时,这里会自动同步。

import { useTheme } from '@caoguo/theme';

const { theme, setTheme, toggle } = useTheme({
  initial: 'caoguo-dark',
  onChange: (name) => map?.setStyle(buildStyle({ theme: name })), // 联动地图换肤
});
setTheme('caoguo-light');

浏览器:构造主题样式

import { buildStyle, darkStyle, lightStyle, injectTheme } from '@caoguo/theme';

// 1. 选择主题
const style = darkStyle;
// 或按需构造
// const style = buildStyle({ theme: 'caoguo-light', notoFonts: true });

// 2. 配合 @caoguo/maplibre 使用
import { Map } from '@caoguo/maplibre';
const map = new Map({ container: 'map', style });

// 3. SPA 场景:注入 data-theme 让 CSS 变量生效
injectTheme('caoguo-dark');

仅注入 CSS 变量主题

import { injectTheme, themeNames } from '@caoguo/theme';
console.log(themeNames); // ['caoguo-dark', 'caoguo-light']
injectTheme('caoguo-dark');

行业主题(六张网真实配色)

六张网(管网 / 电网 / 水网 / 交通 / 算力 / 通信)的真实语义配色已沉淀到本包。INDUSTRY_PALETTES 汇总了各业务包(@caoguo/{grid,water,transport,compute,telecom,pipeline})既已落地的 *Theme.ts 颜色常量,作为权威色板供大屏换肤、图例与 demo 统一复用;registerIndustryThemes() 则将六张网行业主题变体注入注册表,使 buildStyle({ theme: 'caoguo-ind-<key>' }) 可直接使用。

import {
  INDUSTRY_PALETTES,   // 六张网权威色板(语义色 / 分级色 / 状态色)
  INDUSTRY_META,       // 六张网元信息:themeId / 中文名 / 主色
  registerIndustryThemes,
  buildStyle,
  buildIndustryStyle,
} from '@caoguo/theme';

// 1. 注册六张网行业主题(建议在应用启动时调用一次)
registerIndustryThemes();

// 2. 直接构造某张网的行业底图(基于 dark 派生,注入行业主色)
const gridStyle = buildStyle({ theme: 'caoguo-ind-grid' });
// 或显式取派生对象:
const waterStyle = buildIndustryStyle('water', 'dark');

// 3. 复用色板(替代各包各自硬编码颜色)
console.log(INDUSTRY_PALETTES.grid.palette); // { uhv:'#ef4444', high:'#f59e0b', ... }

六张网主色与语义色一览

每网还含 ramp(数值分级色,常用于流量 / 负载 / 信号热力)与 status(状态色,如安全 / 预警 / 危险)。完整取值见 INDUSTRY_PALETTES

行业底图变体基于 caoguo-dark 克隆并在 metadata 注入 cg:industry / cg:industry-label / cg:industry-primary,业务图层与大屏辉光可据此统一取色。如需替换真实矢量源,仍可用 buildStyle({ theme, sourceUrl, glyphs })

CSS 变量

tokens.css 内置 CSS 变量,组件层可直接消费:

:root[data-theme="caoguo-dark"] {
  --cg-bg: #0a0e1a;
  --cg-fg: #e8edf3;
  --cg-accent: #4a9eff;
  /* ... */
}

直接 import 即可:

import '@caoguo/theme/dist/tokens.css';

浏览器 / 环境要求

  • 现代浏览器(Chrome 90+ / Firefox 88+ / Edge 90+)
  • SSR 友好:injectTheme 内置 typeof document 守卫
  • 纯函数模块可在 Node.js 环境单独测试(已含 vitest 用例)
