{"id":40783,"library":"cssnano-nightly","title":"cssnano-nightly","description":"An unofficial nightly release of cssnano, a modular CSS minifier built on top of the PostCSS ecosystem. Current version 0.8.4 wraps the cssnano core and publishes nightly builds for early adopters. Release cadence is tied to nightly automated builds; it is not a stable release channel. Key differentiators: provides early access to upcoming cssnano features and fixes before official release, but comes with no stability guarantees and potential breaking changes between nightlies. Intended for testing and integration validation only, not for production use.","status":"active","version":"0.8.4","language":"javascript","source_language":"en","source_url":"https://github.com/anikethsaha/cssnano-nightly","tags":["javascript","css","compress","minify","optimise","optimisation","postcss","postcss-plugin"],"install":[{"cmd":"npm install cssnano-nightly","lang":"bash","label":"npm"},{"cmd":"yarn add cssnano-nightly","lang":"bash","label":"yarn"},{"cmd":"pnpm add cssnano-nightly","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"cssnano is a PostCSS plugin and requires PostCSS to be installed","package":"postcss","optional":false}],"imports":[{"note":"Package is ESM-only?
