Introduction

Performance is a key factor in modern web applications, and caching plays a vital role in optimizing response times and reducing server load. Next.js, a popular React framework, incorporates server-side caching mechanisms to enhance application speed and efficiency. In this blog, we will explore the various caching techniques in Next.js and how they contribute to performance improvements.
