vite-css-modules

Current stable version is 1.15.0, actively maintained with frequent releases (latest March 2026). Vite plugin that fixes multiple CSS Modules bugs in Vite by integrating CSS Modules properly into the build pipeline instead of delegating everything to postcss-modules. Key differentiators vs Vite's built-in CSS Modules: deduplicates composed styles, applies PostCSS plugins to composes dependencies, throws errors on missing composes classes, and generates accurate TypeScript declarations. Supports Vite 5, 6, 7, and 8, works with both postcss and lightningcss, and generates inline source maps for CSS Modules declarations.
