Node js beginner getting an error

Question

this is my code for a simple node.js application:

var http = require('http'); var fs = require('fs'); var path = require('path'); var url = require('url'); var port = process.env.port || 1337; http.createServer(function onRequest(req, res) { var urlParts = url.parse(req.url); var doc = '/docs' + urlParts.pathname; path.exists(doc, function fileExists(exists) { if (exists) { res.writeHead(200, { 'Content-Type': 'text/plain' }); fs.createReadStream(doc).pipe(res); } else { res.writeHead(404); res.end('Not Fouind\n'); } }); }).listen(port);

When I try to run it I get an error that reads:

path.exists(doc, function fileExists(exists) { ^ TypeError:Undefined is not a function

This is copied off of a tutorial so I'm not sure what's going on. (PS: I'm using Visual Studio)

I think path.exists is deprecated. I've been using fs.exists. Try that.

fs.exists(doc, function fileExists(exists) { if (exists) { res.writeHead(200, { 'Content-Type': 'text/plain' }); fs.createReadStream(doc).pipe(res); } else { res.writeHead(404); res.end('Not Fouind\n'); } });

path.exists is not a function, the function exists in the fs module under fs.exists.
