# 설치 가이드

1. 코드 내려받기

git clone https://github.com/patrickhulce/fontmin-webpack

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd fontmin-webpack

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install --save-dev fontmin-webpack

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

npm install --save-dev fontmin-webpack@^2.0.1

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

npm install --save-dev fontmin-webpack@^1.0.2

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

이 레포의 README에 적힌 실제 명령어를 그대로 가져왔습니다.

Minifies icon fonts to just what is used.

```bash
# for webpack 5
npm install --save-dev fontmin-webpack
# for webpack 4
npm install --save-dev fontmin-webpack@^2.0.1
# for webpack <=3
npm install --save-dev fontmin-webpack@^1.0.2
```

## How It Works

- Examines your webpack output assets to identify font formats that have the same name
- Identifies CSS rules that specify a content property and extracts unicode characters
- Uses `fontmin` to minify the TrueType font to only the used glyphs
- Converts the ttf back to all other formats (supports `ttf`, `eot`, `svg`, `woff`, and `woff2` although you should really only need to care about [woff](http://caniuse.com/#search=woff))
- Replaces the webpack output asset with the minified version

## Usage

#### Install fontmin-webpack

`npm install --save-dev fontmin-webpack`

#### Include Your Icon Font

The example below uses glyphs `\uf0c7` and `\uf0ce`

```css
@font-face {
  font-family: 'FontAwesome';
  src: url('fontawesome-webfont.eot') format('embedded-opentype'), url('fontawesome-webfont.woff2')
      format('woff2'), url('fontawesome-webfont.woff') format('woff'), url('fontawesome-webfont.ttf')
      format('ttf');
}

/**
 * Remove other unused icons from the file.
 */
.fa-save:before,
.fa-floppy-o:before {
  content: '\f0c7';
}
.fa-table:before {
  content: '\f0ce';
}
```

#### Setup Your Webpack Configuration

```js
const FontminPlugin = require('fontmin-webpack')

module.exports = {
  entry: 'my-entry.js',
  output: {
    // ...
  },
  plugins: [
    // ...
    new FontminPlugin({
      autodetect: true, // automatically pull unicode characters from CSS
      glyphs: ['\uf0c8' /* extra glyphs to include */],
      // note: these settings are mutually exclusive and allowedFilesRegex has priority over skippedFilesRegex
      allowedFilesRegex: null, // RegExp to only target specific fonts by their names
      skippedFilesRegex: null, // RegExp to skip specific fonts by their names
      textRegex: /\.(js|css|html)$/,  // RegExp for searching text reference
      webpackCompilationHook: 'thisCompilation', // Webpack compilation hook (for example PurgeCss webpack plugin use 'compilation' )
    }),
  ],
}
```

#### Use in Vue3

In a Vue3 project PurgeCss needs to be executed as a Webpack plugin. 
The easiest way to add Webpack plugins is to declare them in vue.config.js

This is a sample for a project with Vue3 / Tailwindcss 3 / Fontawesome 6
#### **`vue.config.js`**
```js
const webpackPlugins = [];
const __DEBUG__='0'; //turn to 1 for avoiding purgecss and fontmin

// **********************************
// Purgecss unused classes
//
if (__DEBUG__ !== '1') {
  const PurgecssPlugin = require('purgecss-webpack-plugin');
  const glob = require('glob-all')
  const purgeCssPlugin = new PurgecssPlugin({
    paths: glob.sync(
      [
        path.join(__dirname, './public/*.html'),
        path.join(__dirname, './src/**/*.vue'),
        path.join(__dirname, './src/**/*.js')
      ]),
    safelist: [/^sm:/, /^md:/, /^lg:/, /^xl:/, /^2xl:/, /^focus:/, /^hover:/, /^group-hover:/, /\[.*\]/, /^basicLightbox/, /\/[0-9]/, /^tns/],
    fontFace: true
  })
  webpackPlugins.push(purgeCssPlugin);
}

// **********************************
// fontminifying Fontawesome
//
if (__DEBUG__ !== '1') {
  const FontMinPlugin = require('fontmin-webpack');
  const fontMinPlugin = new FontMinPlugin({
    autodetect: true,
    glyphs: [],
    allowedFilesRegex: /^fa[srltdb]*-/, // RegExp to only target specific fonts by their names
    skippedFilesRegex: null, // RegExp to skip specific fonts by their names
    textRegex: /\.(js|css|html|vue)$/,  // RegExp for searching text reference
    webpackCompilationHook: 'compilation', // Webpack compilation hook (for example PurgeCss webpack plugin use 'compilation' )
  });
  webpackPlugins.push(fontMinPlugin);
}

module.exports = {
   runtimeCompiler: true,
   configureWebpack: {
    plugins: webpackPlugins,
    devtool: false,
    mode: 'production',
  },
};
```

Obviously the required dependencies must be added in package.json
#### **`package.json`**
```json
"devDependencies": {
…
    "fontmin-webpack": "^4.0.0",
    "glob-all": "^3.3.0",
    "purgecss-webpack-plugin": "^4.1.3",
    "webpack": "^5.71.0",
…
}
```

## Limitations

- Fonts must be loaded with `file-loader`
- Fonts must have the same name as the TrueType version of the font.
- Font file names are not changed by different used glyph sets ([See #8](https://github.com/patrickhulce/fontmin-webpack/issues/8))
