MERN Nginx reverse proxy setup

Your MERN application is growing, but traffic routing is becoming fragile—clients hit the wrong service, WebSocket connections drop, and scaling across multiple Node/Express instances turns into manual, error-prone work. Without a reverse proxy layer, you also lose a consistent place to enforce timeouts, request limits, caching strategy, and observability for both the API and the frontend.

DevionixLabs sets up a production-grade Nginx reverse proxy tailored to your MERN architecture. We configure Nginx to route requests to your React frontend and Express API reliably, including support for WebSockets and correct header forwarding (Host, X-Forwarded-For, Upgrade/Connection). We also implement safe defaults for performance and stability—connection and buffering settings, upstream health behavior, and clean separation of static assets versus dynamic API calls.

What we deliver:
• Nginx reverse proxy configuration for frontend + API routing with correct header and WebSocket handling
• Upstream definitions aligned to your Node/Express deployment model (single instance or multiple replicas)
• Security-focused request controls (rate limiting hooks, size limits, and timeout tuning) without breaking legitimate traffic
• Environment-specific configuration structure so staging and production behave consistently

We integrate the proxy with your existing MERN deployment workflow so your team can deploy without rewriting infrastructure each release. DevionixLabs also validates routing behavior end-to-end—ensuring that browser navigation, API calls, and real-time features work through the proxy exactly as they do in local environments.

The result is a stable entry point for your MERN stack: fewer routing incidents, predictable behavior under load, and a foundation you can extend for HTTPS, TLS, and advanced traffic management. You get a reverse proxy that improves reliability today and reduces operational friction as your product scales.
