fontkit is an advanced font engine library for Node.js and the browser, used by PDFKit. It parses many font formats and provides glyph shaping, layout, path extraction, color emoji support, and font subsetting.
Use cases
- parse ttf and otf font files in node
- extract svg paths from font glyphs
- shape text with ligatures and kerning
- render color emoji glyphs
- create font subsets for embedding in pdfs
- read font metrics for text layout
- support variable fonts with design axes
When to choose
- you need low-level font parsing and glyph access in JavaScript
- you are building PDF generation or custom text rendering
- you need OpenType/AAT shaping features or font subsetting
When to avoid
- you just need to display text in a browser (use CSS)
- you need a full text layout engine with bidirectional text (consider HarfBuzz)
- you need a non-JavaScript environment
