Packer CLI

Full-featured CLI tool for scaffolding and packaging Node library modules compliant with both Node.js and browsers. At version 2.17.8, it integrates Rollup for bundling, Gulp for task automation, Babel for transpilation, and supports multiple test frameworks (Mocha, Jest, Jasmine, Karma) and style preprocessors (PostCSS, LESS, SASS, Stylus). Differentiates itself by enforcing best practices and providing a unified workflow for file-watching, live-reloading, transpilation, bundling, and unit testing with coverage. Ships TypeScript types, supports React, Handlebars, and JSdom. Release cadence appears irregular; no major releases recently.
