json - How to edit a server-side file in javascript?

Question

I'm making like a messageboard system and I'm already using those XMLHttpRequest things to obtain a JSON database, and I was wondering if it is possible to edit a file using those.

So far my file system looks like this

index.html (node.js + express server file)
public >
   index.html
   message.js (loads posts.json, parses the array, and adds them to the main posts section on the webpage)
   posts.josn (small, database-like json file)
   style.css

posts.json looks like this:

[ { "user":"User", "text":"Message 2" }, { "user":"User", "text":"Message 1" } ]

I would think an easy way to edit this is just to stringify the JSON that I already have from loading the posts, add a new post object thing, and then like send that out to replace the current data in the file.

(p.s. also I know this is probably a terrible way to set this up and I've used socket.io many times before and I probably should use that for serving the files and do that there but I'm too lazy at the moment and I'll probably do so later.)

Thanks!
