{"id":18645,"library":"pakku","title":"Pakku","description":"Pakku (v1.4.1) is a command-line web bundler and compiler that processes entire web sites: it scans for assets, links, pages, and images; versionizes filenames using Git commit IDs (cache busting); optimizes/minifies HTML, JavaScript, CSS, Less, JPEG, PNG, GIF, SVG; and supports data attributes for inline expansion and dev-only stripping. Differentiated by its holistic site-centric approach (vs module bundlers like Webpack) and zero-config philosophy. Released under MIT/BSD. Maintained on GitHub (zanona/pakku). Release cadence is irregular; latest stable v1.4.1 (2020-03-29).
