EndpointLocation

A URL manipulation utility similar to the familiar Location interface (in window). The main difference is that Location's API ¹ only accepts a URL string (and another Location object via toString()), but EndpointLocation's API allows all that plus "construction by configuration" and empty construction for convenience.

let clientEndpoint = new EndpointLocation(
{
    'hostname':'example.com',
    'pathname':'/'.concat( ['path', 'to', 'endpoint'].join( '/' )),
    'params':{'hash':'of', 'url':'parameters'},
    'protocol':'https:',
});
request.get(
    {
        'headers':
        {
            'Accept':'application/json',
            'User-Agent':'request',
        },
        // The convenience of `EndpointLocation`.
        'url':clientEndpoint.href,
        // "https://example.com/path/to/endpoint?hash=of&url=parameters"
    },
    function response_handler( error, httpResponse, responseText )
    {}
);
