How to use Nginx as a reverse proxy for a Node.js server

Node.js is a popular tool for developing fast and scalable web applications but faces challenges like slow code execution and difficulties in serving static content. Nginx, an HTTP and reverse proxy server, helps mitigate these issues by enhancing Node.js performance through caching, load balancing, SSL termination, and serving as a reverse proxy. The tutorial provided guides users through setting up a simple Node.js application, configuring Nginx to act as a reverse proxy server on port 3000, and using advanced configurations like SSL termination and load balancing to optimize the scalability, security, and performance of Node.js applications. Nginx supports multiple scripting languages and offers features like real-time performance tracking, security enhancements, and content caching, making it a valuable tool for web application delivery.
