{"id":14478,"library":"bundler-reactor","title":"Bundler Reactor","description":"Bundler Reactor is a command-line interface (CLI) tool designed to quickly scaffold React single-page applications (SPAs). It provides an opinionated boilerplate setup leveraging `pakit` for asset bundling (handling ES6, JSX, CSS, JSON, code splitting, and livereload), `3dub` as a development server with browser history API fallback, and pre-configured integrations for Babel and ESLint. The tool simplifies initial project setup by generating a project structure and `npm` scripts for common tasks like starting a development server (`npm run start`) and creating production builds (`npm run build`). Currently at version 5.0.3, the project appears to have an infrequent release cadence, with the last update over 1.5 years ago, which may lead to out-of-date dependencies or configurations for a rapidly evolving React ecosystem.","status":"abandoned","version":"5.0.3","language":"javascript","source_language":"en","source_url":"https://github.com/MiguelCastillo/bundler-reactor","tags":["javascript","bundler","bit-bundler","react"],"install":[{"cmd":"npm install bundler-reactor","lang":"bash","label":"npm"},{"cmd":"yarn add bundler-reactor","lang":"bash","label":"yarn"},{"cmd":"pnpm add bundler-reactor","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"This package is primarily a CLI tool and does not export programmatic JavaScript symbols for direct import.
