font-subset-loader2

library1.1.7jsnpmunverified

A webpack loader for subsetting TTF font files to include only specified glyphs, reducing file size. Compatible with webpack 4 and 5, it forked the unmaintained font-subset-loader to update dependencies and fix compatibility. Stable version 1.1.7, with infrequent releases. Alternatives like fontmin-webpack or glyphhanger offer more features, but this loader integrates natively with webpack load chain, processing fonts as resources before file/url-loader.

Loader is used via webpack config, not imported in code.

Webpack config to subset TTF font to include only specified glyphs.

// webpack.config.js module.exports = { module: { rules: [ { test: /\.ttf$/, use: [ { loader: 'font-subset-loader2', options: { glyphs: 'hello, world!' } }, { loader: 'file-loader', options: { name: '[name].[ext]' } } ] } ] } };

Debug

Known issues

gotchaGlyphs containing special characters must be passed via options object, not query string, to avoid webpack parsing issues.

fix

Use 'options: { glyphs: '...' }' instead of inline query string.

affects: all

breakingThis package is incompatible with webpack <4. It requires webpack 4+ and does not work with webpack 3 or earlier.

fix

Upgrade to webpack 4 or 5.

affects: all

gotchaThe loader only works with TTF fonts. Other font formats (OTF, WOFF, etc.) are not supported.

fix

Convert fonts to TTF before using this loader.

affects: all

Errors

Common errors & fixes

Module parse failed: Unexpected character '' (1:0) You may need an appropriate loader to handle this file type.

Missing font-subset-loader2 rule for .ttf files or incorrect loader order.

fix

Ensure webpack config includes { test: /\.ttf$/, use: ['font-subset-loader2'] } and that it is the first loader in the 'use' array.
