Text Rendering Toolkit

Text Rendering Toolkit is a strict TypeScript, ESM-only package family for turning font bytes and Unicode text into renderer-ready data:

• @text-rendering-toolkit/font parses caller-owned font bytes, shapes text, and returns numeric glyph outlines.
• @text-rendering-toolkit/layout prepares multilingual text and produces positioned glyphs, lines, carets, selections, bounds, and decorations.
• @text-rendering-toolkit/sdf converts numeric outlines into deterministic one-channel signed-distance-field bitmaps without a browser or GPU.
• @text-rendering-toolkit/three-webgpu renders completed layouts with Three.js WebGPURenderer.

Each package is independently useful. The runtime dependency direction is:

font → layout ─┐
               ├→ three-webgpu → three
sdf ───────────┘

The SDF package also accepts font outlines structurally without importing the font package at runtime.

Install

Choose only the boundaries your application needs:

pnpm add @text-rendering-toolkit/font
pnpm add @text-rendering-toolkit/layout
pnpm add @text-rendering-toolkit/sdf
pnpm add @text-rendering-toolkit/three-webgpu three

The first public package family is versioned together at 0.1.x. Its APIs are tested through packed, isolated consumers, but remain pre-1.0 and may change between minor releases.

See the documentation source and each package README for API examples and ownership rules. Architecture, validation evidence, and project direction live in ARCHITECTURE.md, docs/validation, and ROADMAP.md.

Development
