Preline Component Library Reference

Preline v4.1.3 is a Tailwind CSS component library with 27 headless plugins. GlassUI draws from Preline's component designs, accessibility patterns, and API conventions -- but builds natively in Svelte 5.

The source lives at tmp/pkg/preline/ in the repo. For the full component inventory with interfaces, HTML structure, and accessibility details, read references/preline-components.md.

Architecture Overview

Each Preline plugin follows this structure:

src/plugins/{name}/
  core.ts        -- main class extending HSBasePlugin
  interfaces.ts  -- TypeScript option/component interfaces
  auto.ts        -- auto-initialization on window load
  types.ts       -- (optional) custom types
  variants.css   -- Tailwind custom variants for state styling
