URLTemplate is a module for creating contextless template functions from simple express routes. Those functions can then be passed in parameters as ordered arguments or as a hash to retrieve the desired URL. Since the functions are contextless, they can also be used client side.
var ut = require("urltemplate");
var myURL = ut({ route:"/article/:id" });
myURL(); // => "/article/:id";
myURL(123); // => "/article/123"
myURL({ id:123 }); // => "/article/123";
var yourURL = ut({ route:"/blog/:blogid/:postid", prefix:"/your" });
yourURL(); // => "/your/blog/:blogid/:postid"
yourURL("abc"); // => "/your/blog/abc/:postid"
yourURL("abc",123); // => "/your/blog/abc/123"
yourURL({ blogid:"def", postid:456 }); // => "/your/blog/def/456"
Pass in an extra argument to add query parameters to the URL. An object argument will be automatically encoded and converted to the form "key1=val1&key2=val2". If you use the hash-first-argument form shown before, extra values are added in the same way.
