vite-plugin-lit-css

Vite plugin that transforms CSS/SCSS imports into Lit-compatible CSSResult or CSSResultGroup objects via constructible stylesheets. Current stable version is 2.2.2, released monthly. Designed exclusively for LitElement projects using Vite, it supports SASS/SCSS and PostCSS preprocessing. Unlike generic CSS handling, it outputs Lit template-literal stylesheets directly. Requires Lit 2/3 and Vite 5–7. TypeScript definitions included. Known limitation: HMR triggers full page reload.
