}About Nginx Config Generator
The NGINX Server Block & Reverse Proxy Config Generator creates production-ready `nginx.conf` configurations for Next.js, Node.js, PHP-FPM, Single Page Apps (SPA), SSL/TLS hardening, Gzip/Brotli compression, and rate limiting.
How to Use Nginx Config Generator
Step 1
Enter your domain name and backend upstream port (e.g. 3000).
Step 2
Select architecture type (Reverse Proxy, Static SPA, or PHP).
Step 3
Toggle desired security and compression options.
Step 4
Copy the generated `nginx.conf` block to `/etc/nginx/sites-available/`.
Practical Use Cases for Nginx Config Generator
Reverse Proxy for Next.js & Node.js Deployments
Configure NGINX reverse proxy blocks to route HTTP/HTTPS traffic to internal Node.js processes running on `http://localhost:3000`.
SPA Routing & Static File Caching (React / Vue)
Set up `try_files $uri $uri/ /index.html;` fallback routing and aggressive static asset caching headers for React and Vite apps.

Key Terminology & Definitions
Reverse Proxy
An application server intermediary that retrieves resources from backend servers on behalf of a client, providing load balancing and SSL termination.
try_files Directive
An NGINX directive that checks the existence of files in order and serves a fallback URI (crucial for Single Page Applications).
