# Deploying an Express App — Express.js

> A quick look at taking Express to production.

## The checklist

Set `NODE_ENV=production`, load secrets from environment variables, listen on `process.env.PORT`, and put a reverse proxy (nginx, or the platform's own) in front.

## Keep it alive

Use a process manager like **PM2**, or let a platform (Render, Railway, Fly.io) manage restarts — plain `node server.js` dies on any uncaught crash.
