svgicons2svgfont

Read a set of SVG icons and ouput a SVG font

svgicons2svgfont is a simple tool to merge multiple icons to an SVG font.

'rect', 'line', 'circle', 'ellipsis', 'polyline' and 'polygon' shapes will be converted to pathes. Multiple pathes will be merged.

Transform attributes support is currenly experimental, report issues if any.

You can test this library with the frontend generator.

You may want to convert fonts to icons, if so use svgfont2svgicons.

Usage

In your scripts

const SVGIcons2SVGFontStream = require('svgicons2svgfont');
const fs = require('fs');
const fontStream = new SVGIcons2SVGFontStream({
  fontName: 'hello',
});

// Setting the font destination
fontStream
  .pipe(fs.createWriteStream('fonts/hello.svg'))
  .on('finish', function () {
    console.log('Font successfully created!');
  })
  .on('error', function (err) {
    console.log(err);
  });

// Writing glyphs
const glyph1 = fs.createReadStream('icons/icon1.svg');
glyph1.metadata = {
  unicode: ['\uE001\uE002'],
  name: 'icon1',
};
fontStream.write(glyph1);

// Multiple unicode values are possible
const glyph2 = fs.createReadStream('icons/icon1.svg');
glyph2.metadata = {
  unicode: ['\uE002', '\uEA02'],
  name: 'icon2',
};
fontStream.write(glyph2);

// Either ligatures are available
const glyph3 = fs.createReadStream('icons/icon1.svg');
glyph3.metadata = {
  unicode: ['\uE001\uE002'],
  name: 'icon1-icon2',
};
fontStream.write(glyph3);

// Do not forget to end the stream
fontStream.end();

CLI interface

All options are available except the log one by using this pattern: --{LOWER_CASE(optionName)}={optionValue}.

svgicons2svgfont --fontname=hello -o font/destination/file.svg icons/directory/*.svg

Note that you won't be able to customize icon names or icons unicodes by passing options but by using the following convention to name your icons files: ${icon.unicode}-${icon.name}.svg where icon.unicode is a comma separated list of unicode strings (ex: 'uEA01,uE001,uE001uE002', note that the last string is in fact a ligature).

There is a few more options for the CLI interface, you can list all of them:

svgicons2svgfont --help
