How to define complex routes with named parameters in express.js?

Question

I want to set up some more complex routes that can include a number of optional parameters. Preferably, I would like to use named parameters for ease of access. Here is an examp

Answer 1

It looks like you want to re-implement the query string using the URL path. My guess is that if you really wanted that, yes, you would have to write your own parsing/interpreting logic. AFAIK express path parameters are positional, whereas the query string is not. Just use a query string and express will parse it for you automatically.

/books?category=sports&author=jack&limit=15?sortby=title

That will enable you to do

req.query.sortby

You may be able to get express to do 1/2 of the parsing for you with a regular expression path like (:key/:value)* or something along those lines (that will match multiple key/value pairs), but express isn't going to then further parse those results for you.

Answer 2

you can send data to view as follow:

//in the server side ...
 app.get('/search/:qkey/:qvalue', function(req, res){
    res.write(JSON.stringify({
      qkey:req.params.qkey;
      qvalue:req.params.qvalue;
    }));
 });

and in the client side... call to ajax

$.ajax({
  type:"POST",
  url:"/search/"+qkey+"/"+qvalue,
  success: function(data){
    var string = eval("(" + data + ")");
    //you access to server response with
    console.log(string.qkey+" and "+ string.qvalue);
  }
});
