Icon-font generation, easy to use and highly configurable.
It also generates TypeScript types, JSON maps of the generated code-points, allowing for a great deal of different usages, e.g. integrating with React type-safe icon components or integration on mobile apps by just combining TTF and JSON generation.
```bash
npm install -g @zupit-it/fantasticon
```
```bash
zupit-fantasticon my-icons -o icon-dist
```
**Note:** Not all options can be specified through the command line - for `formatOptions`, `pathOptions`, `getIconId` and `templates` use a [configuration file](
```
Usage: zupit-fantasticon [options] [input-dir]
Options:
-V, --version output the version number
-c, --config <value> custom config path (default: .fantasticonrc | fantasticonrc | .fantasticonrc.json | fantasticonrc.json | .fantasticonrc.js | fantasticonrc.js)
-o, --output <value> specify output directory
-n, --name <value> base name of the font set used both as default asset name (default: icons)
-t, --font-types <value...> specify font formats to generate (default: eot, woff2, woff, available: eot, woff2, woff, ttf, svg)
-g --asset-types <value...> specify other asset types to generate (default: css, html, json, ts, available: css, scss, sass, html, json, ts)
-h, --font-height <value> the output font height (icons will be scaled so the highest has this height) (default: 300)
--descent <value> the font descent
--normalize [bool] normalize icons by scaling them to the height of the highest icon
-r, --round [bool] setup the SVG path rounding [10e12]
--selector <value> use a CSS selector instead of 'tag + prefix' (default: null)
-p, --prefix <value> CSS class prefix (default: icon)
--tag <value> CSS base tag for icons (default: i)
-u, --fonts-url <value> public URL to the fonts directory (used in the generated CSS)
--debug display errors stack trace (default: false)
--silent run with no logs (default: false)
--help display help for command
```
### Configuration file
Some options (specifically, `formatOptions`, `pathOptions` and `getIconId`) cannot be passed to the CLI directly.
To have more control and better readability, you can create a simple configuration file.
By default, `fantasticon` will look for one of following files in the working directory:
```
.fantasticonrc | fantasticonrc | .fantasticonrc.json | fantasticonrc.json | .fantasticonrc.js | fantasticonrc.js
```
You can specify a custom `--config` option with your configuration file path.
Here's an example `.fantasticonrc.js`:
```js
module.exports = {
inputDir: './icons', // (required)
outputDir: './dist', // (required)
fontTypes: ['ttf', 'woff', 'woff2'],
assetTypes: ['ts', 'css', 'json', 'html'],
fontsUrl: '/static/fonts',
formatOptions: {
// Pass options directly to `svgicons2svgfont`
woff: {
// Woff Extended Metadata Block - see https://www.w3.org/TR/WOFF/#Metadata
metadata: '...'
},
json: {
// render the JSON human readable with two spaces indentation (default is none, so minified)
indent: 2
},
ts: {
// select what kind of types you want to generate (default `['enum', 'constant', 'literalId', 'literalKey']`)
types: ['constant', 'literalId'],
// render the types with `'` instead of `"` (default is `"`)
singleQuotes: true,
// customise names used for the generated types and constants
enumName: 'MyIconType',
constantName: 'MY_CODEPOINTS'
// literalIdName: 'IconId',
// literalKeyName: 'IconKey'
}
},
// Use a custom Handlebars template
templates: {
css: './my-custom-tp.css.hbs'
},
pathOptions: {
ts: './src/types/icon-types.ts',
json: './misc/icon-codepoints.json'
},
codepoints: {
'chevron-left': 57344, // decimal representation of 0xe000
'chevron-right': 57345,
'thumbs-up': 57358,
'thumbs-down': 57359
},
// Customize generated icon IDs (unavailable with `.json` config file)
getIconId: ({
basename, // `string` - Example: 'foo';
relativeDirPath, // `string` - Example: 'sub/dir/foo.svg'
absoluteFilePath, // `string` - Example: '/var/icons/sub/dir/foo.svg'
relativeFilePath, // `string` - Example: 'foo.svg'
index // `number` - Example: `0`
}) => [index, basename].join('_') // '0_foo'
};
```
Once installed the package, you need to create two folders in your project: one for the SVG files and another for the generated files.
In the `package.json` you can add the following script for convenience:
```json
"scripts": {
...
"generate-icons": "node node_modules/zupit-fantasticon/bin/fantasticon <PATH_TO_SVG_ICONS_FOLDER> -o <PATH_TO_OUTPUT_FOLDER>"
...
},
```
Then you can run `npm run generate-icons` to generate the icon font.
After generating the assets, in the output folder you will find the `icons.css` file, this file needs to be included in the `index.html` file like so:
`<link href="<PATH_TO_OUTPUT_FOLDER>/icons.css" rel="stylesheet">`
You can use the icons in your Angular components like so:
```html
<i class="icon icon-<ICON_NAME>"></i>
```
where `<ICON_NAME>` is the name of the generated icon found in the `icons.ts` enum.
```js
import { generateFonts } from 'zupit-fantasticon';
generateFonts().then(results => console.log('Done', results));
```
```js
import { generateFonts } from 'zupit-fantasticon';
generateFonts({
name: 'icons',
fontTypes: [FontAssetType.EOT, FontAssetType.WOFF2, FontAssetType.WOFF],
assetTypes: [
OtherAssetType.CSS,
OtherAssetType.HTML,
OtherAssetType.JSON,
OtherAssetType.TS
],
formatOptions: { json: { indent: 2 } },
templates: {},
pathOptions: {},
codepoints: {},
fontHeight: 300,
round: undefined, // --
descent: undefined, // Will use `svgicons2svgfont` defaults
normalize: undefined, // --
selector: null,
tag: 'i',
prefix: 'icon',
fontsUrl: null
}).then(results => console.log(results));
```
Icon names and className will be generated from a slug of the relative path + basename of each `.svg` file found in the input directory.
This allows arranging your icons in namespaces, which can be useful if a project uses a large number of icons.
Considering the following `./icons` input directory:
```
icons
├── logo.svg
├── social
│ ├── facebook.svg
│ └── twitter.svg
└── symbol
└── chevron
├── left.svg
└── right.svg
```
Running `fantasticon ./icons -o dist` will generate a font-set with the following Icon IDs / CSS selectors:
And the generated icon IDs would be:
| Icon ID | CSS selector |
| ---------------------- | ---------------------------- |
| `social-facebook` | `.icon.icon-social-facebook` |
| `social-twitter` | `.icon.icon-social-twitter` |
| `symbol-chevron-left` | `.icon.icon-chevron-left` |
| `symbol-chevron-right` | `.icon.icon-chevron-right` |
You can provide a `getIconId` function via the configuration file to customize how the icon IDs / CSS selectors are derived from the filepath. The function will receive relative paths to the icon and the input directory as arguments, and must return a unique string to be used as the ID.
The library is currently actively maintained for for Node 16.x.x support or above
