React Hooks transformed how we write React components. From useState to useEffect to custom hooks — this guide covers every important hook with practical examples you'll actually use in real projects.
Next.js 15 brought major improvements to caching, async APIs, the Turbopack bundler, and React 19 support. This guide covers every significant change with code examples so you know exactly what's new and how to use it.
The Next.js App Router is now the default way to build Next.js apps. It brings file-based routing, layouts, server components, streaming, and more. This guide covers everything you need to master the App Router from scratch.
Next.js Server Actions let you run server-side code directly from your React components — no API routes needed. Form submissions, database mutations, and server logic have never been this clean. Here's everything you need to know.
React Server Components (RSC) are the biggest architectural shift in React's history. They run on the server, fetch data without useEffect, and send zero JavaScript to the client. This guide explains everything about RSC in Next.js with practical patterns.
In recent years, React has emerged as one of the most popular JavaScript libraries for building user interfaces, thanks to its component-based architecture and virtual DOM. When combined with TypeScript, a statically-typed superset of JavaScript, React becomes even more powerful, offering enhanced type safety and code maintainability.
Next.js 13, the latest iteration of the popular React framework, combined with tRPC, an efficient data fetching and API client for React, opens up exciting possibilities for web developers. In this comprehensive guide, we will explore the best practices for using Next.js 13 and tRPC to create high-performance, data-driven web applications.
