The shadcn/ui FullCalendar Example is a practical demonstration of integrating FullCalendar, one of the most popular JavaScript calendar libraries, with Next.js and shadcn/ui components to create modern scheduling and event management interfaces. Built with Next.js 14, React, TypeScript, Tailwind CSS, and React Aria for accessibility, this example project shows developers how to combine FullCalendar's powerful features with shadcn/ui's beautiful component design system. The implementation includes a fully interactive calendar with month, week, and day views, event creation and editing with modal dialogs using shadcn/ui Dialog components, drag-and-drop event rescheduling directly on the calendar, event deletion and management capabilities, responsive design that adapts to mobile and desktop screens, accessible UI patterns through React Aria integration, and customizable styling that matches shadcn/ui's design language. The project demonstrates how to properly initialize FullCalendar in a Next.js environment, manage calendar state in React components, style FullCalendar to match shadcn/ui themes, and handle event CRUD operations with TypeScript type safety. This template is ideal for building appointment scheduling systems for healthcare or service businesses, team calendar applications for project management, event management platforms for conferences or meetups, booking systems for resources or meeting rooms, and any application requiring rich calendar functionality with a modern UI. The example serves as a solid foundation for developers who want to quickly add calendar features to their Next.js applications without starting from scratch.

The WordPress Plugin Boilerplate is a comprehensive starter template that brings modern web development practices to WordPress plugin development by integrating React, TypeScript, SASS, Tailwind CSS, shadcn/ui components, Vite for blazing-fast builds, Storybook for component development, and Hot Module Replacement for instant feedback during development. This boilerplate eliminates the traditional pain points of WordPress plugin development by providing a Laravel-inspired custom ORM for database operations, flexible API routing for REST endpoints, simplified shortcode generation with custom rendering, seamless data passing between PHP backend and React frontend, and a CLI tool for rapid plugin scaffolding and configuration. The development workflow is streamlined with npm run dev for full development mode with HMR, separate npm run dev:frontend and npm run dev:admin commands for focused development, npm run build to compile production-ready assets, and npm run release to create distributable plugin packages. The boilerplate includes Storybook integration for isolated component development and documentation, TypeScript for type safety across JavaScript code, SASS and Tailwind CSS for flexible styling options, shadcn/ui and Headless UI for accessible component primitives, and proper WordPress hooks and filters integration maintaining compatibility with the WordPress ecosystem. This template is invaluable for developers building commercial WordPress plugins with modern UIs and complex functionality, agencies developing multiple client plugins who need consistent, maintainable architecture, teams transitioning from jQuery-based WordPress development to React, freelancers who want professional development experience in WordPress projects, and anyone frustrated with traditional WordPress plugin development workflows. The project demonstrates how to integrate modern JavaScript frameworks into WordPress without fighting the platform, structure plugin code for maintainability and testability, implement database models and API routes in WordPress context, build component libraries with Storybook for WordPress admin interfaces, and accelerate WordPress plugin development with contemporary tooling.
