React Cosmos Webpack Plugin

The official Webpack plugin for React Cosmos (v7.3.0), a development tool for building isolated React component libraries and fixture-based testing. This plugin integrates React Cosmos with Webpack-based projects (e.g., Create React App, custom Webpack configs). React Cosmos 7 supports React 18/19 and Next.js 15, with a revamped UI, improved Vite plugin, and peer dependencies on react, react-dom, react-cosmos, and webpack. Releases follow a monthly cadence. Key differentiators: zero-config setup for Webpack, static prerendering support, and seamless integration with the Cosmos ecosystem for component-level development.
