Node.js + Nginx - What now?

Question

I\'ve set up Node.js and Nginx on my server. Now I want to use it, but, before I start there are 2 questions:

1. How should they work together? How should I handl

Answer 1

We can easily setup a Nodejs app by Nginx acting as a reverse proxy.
The following configuration assumes the NodeJS application is running on 127.0.0.1:8080,

  server{
     server_name domain.com sub.domain.com; # multiple domains

     location /{ 
      proxy_pass http://127.0.0.1:8080;  
      proxy_set_header Host $host;
      proxy_pass_request_headers on;  
     }

     location /static/{
       alias /absolute/path/to/static/files; # nginx will handle js/css
     }
   } 

in above setup your Nodejs app will,

• get HTTP_HOST header where you can apply domain specific logic to serve the response. '

• Your Application must be managed by a process manager like pm2 or supervisor for handling situations/reusing sockets or resources etc.

• Setup an error reporting service for getting production errors like sentry or rollbar

NOTE: you can setup logic for handing domain specific request routes, create a middleware for expressjs application
