Question

I’m using Node.js with Express, Connect, and Jade. I want to provide an absolute link to a route in my application, but I can’t find how to do this. I must be missing something, because this seems like a simple task.

I can do this: /myroute

But what I want is this: http://localhost:3000/myroute

There must be a helper somewhere that does this, right?

Answer 1

I created my own helper for this, which doesn’t feel like the greatest solution.

Helpers = {
    toAbsolute: ( url, req ) ->
        'http://' + req.headers.host + url
}

DynamicHelpers = {
    req: ( req, res ) ->
        req
}

exports.Helpers = Helpers
exports.DynamicHelpers = DynamicHelpers

I add the helpers in my app.coffee file:

helpers = require './helpers.js'

# Helpers
app.helpers helpers.Helpers
app.dynamicHelpers helpers.DynamicHelpers

In my [jade] view, this is what I do to get an absolute URL from a relative URL:

| <a href="#{ toAbsolute( '/relativeUrl', req ) }">link text</a>
