Yumma CSS 3.20

Achieve 0 3rd-party dependencies & remove minification.

Yumma CSS 3.20

Dependency Free

Yumma CSS 3.20 ships with 0 3rd-party dependencies across all packages (core, nitro, cli, intellisense, runtime). 3rd party libraries are bundled at build time rather than installed at runtime, reducing install size & improving stability.

ESM Only

All packages now output ESM only, embracing modern JavaScript standards. Update your setup if you consume any Yumma CSS package in a CJS context.

Breaking Changes

Minification Removed

The buildOptions.minify option has been removed from the CLI config. Vite, Webpack, Next.js & Astro already handle CSS minification — use your preferred build pipeline to minify Yumma CSS output instead.
