package.json Plugin for Rolldown

A powerful and flexible plugin for Rolldown that enhances package.json handling.

• Package Transformation
  Automated copying and modification of package.json, allowing selective removal of fields to produce a clean, production-ready manifest.

• Dynamic Exports Generation
  Automatically generates exports maps based on build outputs, ensuring correct module resolution for ESM and CommonJS environments.

• Dependency Optimization
  Integrates with the build pipeline to control dependency handling and reduce unnecessary bundle inclusion.

• Build-Time Integration
  Seamlessly hooks into the Rolldown lifecycle to perform transformations efficiently during the build process.
