}

Or you can generate the file separately:

const { generateIconsSource } = require('svgtofont/src/generate');  
const path = require('path');   

async function generate () {    
  const outPath = await generateIconsSource({   
    src: path.resolve(process.cwd(), 'svg'),    
    dist: path.resolve(process.cwd(), 'dist'),  
    fontName: 'svgtofont',  
  });   
}   

generate();

Type: Boolean
Default value: false

Output ./dist/info.json, The content is as follows:

{
  "adobe": {
    "encodedCode": "\\ea01",

    "className": "svgtofont-adobe",
    "unicode": "&#59905;"
  },
  ...
}

src

Type: String
Default value: svg

output path

emptyDist

Type: String
Default value: false

Clear output directory contents

fontName

Type: String
Default value: iconfont

The font family name you want.

styleTemplates

Type: String Default value: undefined

The path of the templates, see src/styles or test/templates/styles to get reference about how to create a template, file names can have the extension .template, like a filename.scss.template

startUnicode

unicode start number

getIconUnicode

Get Icon Unicode

getIconUnicode?: (name: string, unicode: string, startUnicode: number) 
      => [string, number];

useNameAsUnicode

Type: Boolean
Default value: false

should the name(file name) be used as unicode? this switch allows for the support of ligatures.

let's say you have an svg with a file name of add and you want to use ligatures for it. you would set up your processing as mentioned above and turn on this switch.

{
  ...
  useNameAsUnicode: true
}

while processing, instead of using a single sequential char for the unicode, it uses the file name. using the file name as the unicode allows the following code to work as expected.

.icons {
  font-family: 'your-font-icon-name' !important;
  font-size: 16px;
  font-style: normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

<i class="icons">add</i>

as you add more svgs and process them into your font you would just use the same pattern.

<i class="icons">add</i>
<i class="icons">remove</i>
<i class="icons">edit</i>

useCSSVars

Type: Boolean
Default value: false

consoles whenever {{ cssString }} template outputs unicode characters or css vars

classNamePrefix

  include?: RegExp;
  /**

Using With React

Icons are used as components. v3.16.7+ support.

import { Adobe, Alipay } from '@uiw/icons';

<Adobe style={{ fill: 'red' }} />
<Alipay height="36" />

In the project created by create-react-app

import logo from './logo.svg';

<img src={logo}  />

import { ReactComponent as ComLogo } from './logo.svg';

<ComLogo />

In the project created by webpack

yarn add babel-plugin-named-asset-import
yarn add @svgr/webpack

// webpack.config.js
[
  require.resolve('babel-plugin-named-asset-import'),
  {
    loaderMap: {
      svg: {
        ReactComponent: '@svgr/webpack?-svgo,+ref![path]',
      },
    },
  },
],

import { ReactComponent as ComLogo } from './logo.svg';

<ComLogo />

Using With ReactNative

A unique component named after the font name is generated.

Props are TextProps and are used as inline style.

In addition, the iconName prop is mandatory and refers to svg names written in camelCase

SvgToFont.jsx
// ↓↓↓↓↓↓↓↓↓↓

import { SvgToFont } from './SvgToFont';

<SvgToFont fontSize={32} color="#fefefe" iconName={"git"}  />

SvgToFont.d.ts
// ↓↓↓↓↓↓↓↓↓↓

import { TextStyle } from 'react-native';

export type SvgToFontIconNames = 'git'| 'adobe'| 'demo' | 'left' | 'styleInline'

export interface SvgToFontProps extends Omit<TextStyle, 'fontFamily' | 'fontStyle' | 'fontWeight'> {
  iconName: SvgToFontIconNames
}

export declare const SvgToFont: (props: SvgToFontProps) => JSX.Element;
