I'm getting into Node.js at the moment and love how I can use my front-end knowledge to create server-side applications. However, the thing I love about PHP is you can just post to or execute/open a file, and it is automatically ran by the server. The thing I don't like about PHP is the syntax and the speed - I want to use Node.js and Javascript for all of my server-side functionality (e.g. a billing script or registration script).
So... Is there a way I can run a Node.js application as one would with a PHP script, and by that I mean without creating a constantly running server and having to run "node app.js" in the terminal for every script? Like... Is there some sort of nginx thing I can write to make this work? I don't want to run the whole site on a Node.js server either.
