Deploy an API to Production Using Nginx

In this project, we'll deploy a production-ready REST API using Nginx (pronounced as engine x) as a reverse proxy server and web server to enhance security, performance, and scalability. Nginx is an industry-standard solution for API deployment that shields backend servers from direct exposure, efficiently handles client requests, and provides load balancing capabilities. We'll explore multiple deployment strategies including manual execution, process management with PM2, and Docker containerization, then secure the application with firewall configuration, rate limiting, and XSS attack prevention.

We'll start by running the API manually to understand the baseline setup, then implement PM2 process manager for automatic restarts and process monitoring. Next, we'll containerize the application using Docker for consistent deployment across environments. We'll configure Nginx as a reverse proxy to forward requests to the backend API, hiding server details and adding a security layer. We'll extend the Nginx configuration to handle multiple API endpoints with custom routing rules and URL rewriting.

Finally, we'll harden the deployment by configuring UFW firewall rules to restrict unauthorized access, implementing request rate limiting to prevent DDoS attacks and abuse, and adding HTTP headers to mitigate cross-site scripting (XSS) vulnerabilities. By the end, we'll have a secure, scalable production API deployment demonstrating Nginx reverse proxy configuration, Docker containerization, PM2 process management, server security hardening, and API security best practices applicable to any production web server environment.
