The Nucleux engineering surface — installation, design tokens, components, code examples, API reference. Coming with the first SDK release.

Install with npm or pnpm, scaffold a Nucleux project, render the first pattern in under a minute.

Colour, type, spacing, shadow, motion — every visual decision exposed as a CSS variable and a Figma variable, bound 1:1.

React + headless primitives for every pattern in the library — composable, accessible, themeable, framework-agnostic.

Runnable snippets you can drop in. One per pattern, plus longer scenarios that compose several patterns at once.

Every prop, slot, event, hook — typed in TypeScript, documented inline, with default values and edge-case notes.

How to theme, how to extend a pattern, how to bring your own LLM provider, how to ship with confidence.
