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 🙏

Readme

@wemt/fontawesome-toolkit

一个提取和转换 FontAwesome 图标的综合工具库,用于从项目中提取已使用的 FontAwesome 图标,并将 SVG 图标转换为 Web 字体(TTF、WOFF、WOFF2、EOT),同时自动生成 CSS 文件。

✨ 核心功能

🔍 SVG 提取模块

自动扫描项目中的 FontAwesome 图标使用情况,提取并复制到指定目录。

功能特性:

  • 自动扫描项目代码,识别使用的图标
  • 提取图标并生成使用清单 JSON 文件
  • 支持自定义扫描路径和匹配规则
  • 支持多种图标样式(solid、regular、brands)

适用场景:

  • 微信小程序开发
  • 需要按需加载图标的移动端应用
  • 优化打包体积,只包含实际使用的图标
  • 需要自定义图标组件的项目

🎨 字体生成模块

将 SVG 图标转换为 Web 字体文件,自动生成对应的 CSS。

功能特性:

  • 支持多种字体格式(TTF、WOFF、WOFF2、EOT)
  • 自动生成 CSS 文件和 @font-face 声明
  • 自动分配 Unicode 码点(默认从 0xE001 开始)
  • 支持自定义 CSS 模板和字体元数据

适用场景:

  • Web 应用使用图标字体
  • 将 SVG 图标转换为字体以减少 HTTP 请求
  • 需要在 CSS 中使用图标的场景
  • 自定义图标字体项目

🚀 集成方式

  • Vite 插件:构建时自动执行
  • 集成函数:同时使用 SVG 提取和字体生成
  • 独立模块:按需使用单个功能
  • 模块化设计:灵活组合

⚠️ 注意事项

  • 确保项目中已安装 @fortawesome/fontawesome-free
  • Vite 插件会在构建开始时(buildStart 钩子)执行
  • 建议将输出目录添加到 .gitignore,在构建时自动生成
  • 默认匹配规则适用于 fas fa-homefar fa-user 等格式
  • 如果使用其他格式,需要自定义 scan.match 正则表达式

📦 安装

npm install @wemt/fontawesome-toolkit --save-dev

🏗️ 架构说明

本库采用模块化设计,包含两个完全独立的模块:

  • extractor - SVG 提取模块
  • font - 字体生成模块

每个模块都可以独立使用,也可以通过集成函数组合使用。

📖 使用方法

方式一:独立使用 SVG 提取模块

import { extractSvgIcons, defaultExtractorConfig } from "@wemt/fontawesome-toolkit";

const config = {
  ...defaultExtractorConfig,
  scan: {
    path: ["src"],
    ext: [".vue", ".ts"],
    match: [/fa[srb]\s+(fa-[\w-]+)/g],
  },
  output: {
    path: "dist/icons",
    name: "icons.json",
  },
  icon: {
    path: ["node_modules/@fortawesome/fontawesome-free/svgs/solid"],
    ext: [".svg"],
    prefix: "fa-",
  },
};

const iconMap = await extractSvgIcons(config);
// 返回: { "home": "/path/to/home.svg", "user": "/path/to/user.svg", ... }

方式二:独立使用字体生成模块

import { generateFont, defaultFontConfig } from "@wemt/fontawesome-toolkit";

// 假设你已经有了图标映射
const iconMap = {
  home: "/path/to/home.svg",
  user: "/path/to/user.svg",
};

const config = {
  font: {
    ...defaultFontConfig,
    enabled: true,
    fontName: "my-icons",
    formats: ["ttf", "woff", "woff2"],
    output: {
      fontPath: "dist/fonts",
      cssPath: "dist/css",
      cssFileName: "icons.css",
    },
    cssPrefix: "icon",
    startCodepoint: 0xe001,
  },
};

await generateFont(iconMap, config);
// 生成字体文件和 CSS 文件

方式三:使用集成函数(推荐)

同时使用 SVG 提取和字体生成:

import fastk from "@wemt/fontawesome-toolkit";

await fastk({
  // SVG 提取配置
  scan: {
    path: ["src"],
    ext: [".vue"],
    match: [/fa[srb]\s+(fa-[\w-]+)/g],
  },
  output: {
    path: "dist/icons",
    name: "icons.json",
  },
  icon: {
    path: ["node_modules/@fortawesome/fontawesome-free/svgs"],
    ext: [".svg"],
    prefix: "fa-",
  },
  // 字体生成配置(可选)
  font: {
    enabled: true,
    fontName: "my-icons",
    formats: ["ttf", "woff", "woff2"],
    output: {
      fontPath: "dist/fonts",
      cssPath: "dist/css",
      cssFileName: "icons.css",
    },
  },
});

方式四:作为 Vite 插件使用

基础使用

vite.config.jsvite.config.ts 中配置插件:

import { defineConfig } from "vite";
import { FontawesomeToolkitPlugin as fastk } from "@wemt/fontawesome-toolkit";

export default defineConfig({
  plugins: [
    fastk({
      scan: { path: ["src"], ext: [".vue"] },
      output: { path: "dist/icons" },
      icon: {
      path: ["node_modules/@fortawesome/fontawesome-free/svgs"],
        prefix: "fa-",
      },
      // 可选:启用字体生成
      font: {
        enabled: true,
        fontName: "my-icons",
        formats: ["ttf", "woff2"],
      },
    }),
  ],
});

完整配置示例

import { defineConfig } from "vite";
import { FontawesomeToolkitPlugin as fastk } from "@wemt/fontawesome-toolkit";

export default defineConfig({
  plugins: [
    fastk({
      // SVG 提取配置
      scan: {
        path: ["src"],
        ext: [".vue", ".js", ".ts"],
        match: [/fa[srb]\s+(fa-[\w-]+)/g],
      },
      output: {
        path: "src/assets/fontawesome/svg",
        name: "fortawesome.json",
      },
      icon: {
        path: ["node_modules/@fortawesome/fontawesome-free/svgs"],
        ext: [".svg"],
        prefix: "fa-",
      },
      // 字体生成配置
      font: {
        enabled: true,
        fontName: "fontawesome-icons",
        formats: ["ttf", "woff", "woff2"],
        output: {
          fontPath: "src/assets/fontawesome/fonts",
          cssPath: "src/assets/fontawesome",
          cssFileName: "fontawesome-icons.css",
        },
        cssPrefix: "fa",
        startCodepoint: 0xe001,
        metadata: {
          fontName: "FontAwesome Icons",
          version: "1.0.0",
          description: "Custom FontAwesome icon font",
        },
      },
    }),
  ],
});
