some nits inline, no hard feelings for any of them

nit: we probably should const/let here instead of var
(does not make a difference but it's a nicer behavior
in js)

nit: this would probably be more correct and shorter by doing

if (remote) {

(e.g. remote === null would be valid here)

if we *really* want to be safe about the contents it should be

if (typeof remote === 'string' && remote)

nit: i'd prefer interpolated strings in new code

url += `/${remote_type}/remotes/${remote}`;

same here

same hint as above should probably be

if (!remote) {

or

if (typeof remote !== 'string' || !remote) {
