NailusCSS

Instant on-demand atomic CSS engine with zero runtime output.

NailusCSS ships a processor, a CLI, plugin entry points, an attributify mode, and a lang="nailus" style parser for authoring utilities and generated CSS from templates.

Installation

npm install nailuscss

Quick Start

Generate a single CSS file from HTML and template files:

npx nailuscss "src/**/*.{html,tsx,vue,svelte}" -o nailus.css

Generate CSS in watch mode with preflight enabled:

npx nailuscss "src/**/*.{html,tsx,vue,svelte}" -t -d -o nailus.css

Use a config file:

npx nailuscss "src/**/*.{html,tsx,vue,svelte}" -f nailus.config.ts -o nailus.css

Local Development

pnpm install
pnpm build
pnpm test
pnpm lint

Package Layout

• src/lib: processor core, variants, extraction, utilities
• src/cli: command-line interface and file watching
• src/plugin: official plugin entry points
• src/utils/parser: class, HTML and CSS parsers
• test: runtime, snapshot and typing coverage

Status

The published npm package is expected to ship compiled files from dist/. The root repository keeps source, tests and examples for development.
