Node.js/Express routing with get params

Question

Let's say I have get route like this:

app.get('/documents/format/type', function (req, res) {
   var format = req.params.format,
       type = req.params.type;
});

So if I make request like

http://localhost:3000/documents/json/mini

in my format and type variables will be 'json' and 'mini' respectively, but if I make request like

http://localhost:3000/documents/mini/json

not. So my question is: how can I get the same variables in different order?

You don't `documents/mini/json` is `format == mini` and `type == json`. URL's are not unordered bags of parameters — Raynos, Dec 14 '11 at 15:38

Your route isn't ok, it should be like this (with ':')

app.get('/documents/:format/:type', function (req, res) {
   var format = req.params.format,
       type = req.params.type;
});

Also you cannot interchange parameter order unfortunately. For more information on req.params (and req.query) check out the api reference here.

//var sanitizer = require('sanitizer'); var format = sanitizer.escape(req.params. format); You really should sanitize the result. Or else your website has a HUGE vulnerability – user3806549 Oct 12 '15 at 18:36

For Query parameters like example.com/test?format=json&type=mini format, then you can easily receive it via req.query.<param>

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

Thanks. Your answer is also useful for me! – Erik Nov 17 '17 at 13:08
This made it so much easier to deal with a parameter that is a URL itself. – pseudosavant Jul 21 '18 at 20:08
+1 This answers the question in the title, which I came here to find (the actual question has nothing to do with get params). – Val Kornea Sep 10 '21 at 18:35
