Next.js is a popular React-based framework for building server-side rendered (SSR) web applications. It provides developers with a comprehensive toolset to build scalable and high-performing applications that can handle complex use cases with ease. The latest release, Next.js 13, brings a host of new features and improvements to the table that make it even more powerful and developer friendly. In this blog post, we'll explore some of the key highlights of Next.js 13 and what they mean for developers.
Faster Builds and Smaller Bundles
One of the most significant improvements in Next.js 13 is its faster build times and smaller bundle sizes. The framework now uses the latest version of webpack (5.67.0) and supports persistent caching, which can dramatically reduce the build time of your application. Additionally, Next.js 13 introduces a new experimental feature called "Optimized Server Components" (OSC), which can further improve the performance of your application by reducing the server-side rendering time.
Another exciting feature of Next.js 13 is its support for "Web Vitals." Web Vitals are a set of metrics introduced by Google to measure the user experience of web pages. Next.js 13 can now automatically measure and report on these metrics, providing developers with valuable insights into how their application is performing.

Improved TypeScript Support
Next.js 13 also brings several improvements to its TypeScript support. The framework now uses a new version of the TypeScript compiler (4.5), which provides better performance and type checking. Additionally, Next.js 13 includes improved error messages and better support for TypeScript-based configuration files, making it easier for developers to work with TypeScript in their Next.js applications.
