Server configuration for Node.js application

Question

I am trying to move an application off of PHP and onto Node.js. The PHP application uses an Apache server and has a tileservices.conf file that is necessary for the app to work. How would I move over the configuration in this file to a Node application?

Alias /tiles /sandbox/TileServices/www/TileStreamer.php
Alias /thumbs /sandbox/TileServices/www/ThumbStreamer.php
Alias /MosaicTest /sandbox/TileServices/www/MosaicTest

Edited:

//a ton of info on routing http://expressjs.com/en/guide/routing.html

for the first part (until first 2x new line)

you pretty much need express to do the following:

app.get('/tiles', function (req, res) {
  res.send('GET request to /tiles'); //or some other logic
});
app.get('/thumbs', function (req, res) {
  res.send('GET request to /tiles'); //or some other logic
});
app.get('/MosaicTest', function (req, res) {
  res.send('GET request to /tiles'); //or some other logic
});

Second part:

// ^/1.0.0/([a-zA-Z0-9]*)/([0-9]*)/([0-9]*)/([0-9]*)\.[a-zA-Z]*$

app.get('/1.0.0/:param1/:param2/:param3/:param4', function (req, res) {
  var param1 =req.params.param1,
   param2 = req.params.param2,
   param3 = req.params.param3,
   param4 = req.params.param4;

  res.send('your first route parameter is '+param1); //or some other logic
});

First part will probably not be a problem becase Node.js will NOT serve directories and files unless you program it too. So your server is protected.

Second part if those are files (like images) you probably need to think of way to send those to the user trough node. If those are just pages/other data you will serve trough Node you basically need to filter the IP-s that access them so something along the lines of

//    this goes after your route definition
// so after something like app.get('/MosaicTest', function (req, res) { 
var ip = req.ip; 
if (ip == '127.0.0.1') {
    res.send('ip not allowed');
    res.end();
}
// close route definition });

might help

Sadly I am no node.js expert myself so you will need to look for other answers or ask more specific questions to get it all done.

Hope it all helps you on your way! :)
