What are the best practices for deploying an Express application?

When deploying an Express application, consider using a process manager like PM2, setting up environment variables, and ensuring your app is behind a reverse proxy like Nginx.

Why should I use a process manager like PM2?

PM2 helps manage your application by keeping it alive, allowing for easy restarts, and providing monitoring features.

What are environment variables and why are they important?

Environment variables store configuration settings outside your code, making your application more secure and easier to manage.

How do I set up a reverse proxy with Nginx?

To set up Nginx as a reverse proxy, you need to configure the Nginx server block to forward requests to your Express app's port.
