问题:

I've created a function that can build nested urls like so. I was wondering if there existed a more mainstream library to build urls / uris like this. I'd rather use a standard.

utility.urlConstruct({
    "scheme": "https://",
    "domain": "domain.com",
    "path": "/login",
    "query":{
        "user":"thomasreggi",
        "from":utility.urlConstruct({
            "scheme": "https://",
            "domain": "redirect.com",
            "path": "/funstuff",
        }),
    }
});

Spits out

https://domain.com/login?user=thomasreggi&from=https%3A%2F%2Fredirect.com%2Ffunstuff

The correct answer is node's built in URL library.

Specifically

url.format(urlObj)

jQuery does this internally for its AJAX calls. Perhaps there is a way to access the internal functionality.

Al least there are standard conventions:

the scheme (or protocol) excludes //
your domain is called host (and can include sub-domains or port)
path is called pathname
query is a list of parameters
you might also need a hash

Then it is pretty straightforward, so no real need for a library. You'll find some libraries out there, like jsuri, but their purpose is more to help for parsing than construct (for example to address cross-browser inconsistencies with pathname).
