pkg-bundler

pkg-bundler is a zero-configuration Rollup bundler for npm packages, pre-configured with Babel, that automatically generates CommonJS and ES module bundles from a single entry point. Version 1.0.0-1 is the current stable release, with no active development observed. It differentiates from similar tools like microbundle or rollup-starter by enforcing a specific project structure (`.babelrc`, `main`/`module` fields) and providing a single CLI command with no configuration files required. However, its dependency on `rollup` and `babel` is opaque, and there is no support for TypeScript or modern bundling needs. Release cadence is low; the package is largely untended.
