Overview:

React ESI is a powerful cache library designed for vanilla React and Next.js applications to significantly enhance performance by storing fragments of server-side rendered pages in edge cache servers. This caching system allows for faster loading times for subsequent visits by serving cached fragments in milliseconds from servers closer to the end users. React ESI supports various cloud cache providers and the open-source Varnish cache server, enabling users to improve website performance, SEO, and reduce hosting costs while being energy-efficient.

Features:

• Blazing-Fast Server-Side Rendering: Improves application performance by caching fragments of server-side rendered pages.
• Edge Cache Support: Stores fragments in edge cache servers for quicker retrieval by end users.
• TTL Specification: Allows setting different Time To Live (TTL) per React component for efficient caching.
• Cloud Cache Providers Compatibility: Natively supports well-known cloud cache providers like Cloudflare Workers, Akamai, and Fastly.
• Reduced Hosting Costs: Dramatically decreases hosting costs by optimizing performance and caching resources.
• Improved SEO: Enhances website SEO by boosting loading speeds and overall performance.
• Environment-Friendly: Contributes to energy efficiency by reducing the energy consumption of applications.

Installation:
