node.js - Any simple way to create link in ExpressJS? -

sometimes need create absolute link in web site.

like http://example.com/xxxx/xxxx?foo=bar not /xxxx/xxxx?foo=bar

here has anyway create simple helper express manually?

just like:

app.locals.url = function ( pathto, opts ) {     // somethings here. } 

i think may need ssl check, host , route check or somethings.

you can create full url :

var url = req.protocol + '://' + req.get('host') + req.originalurl; 

them can redirect url
