It would be really useful to have utilities for managing cookies (parsing cookies, setting cookies)

I was going to take a crack at adding cookie based session support to shelf_auth but then ran into this issue with lack of cookie support in shelf so I had to shelve the idea (no pun intended. OK maybe a little)

Anders - I implemented very basic session support by copying the dart:io cookie code. See https://github.com/wstrange/shelf_simple_session

Thanks Warren. I'll take a look. I'm not wanting to get involved in any of the session storage side in shelf_auth. Rather just the authentication side (i.e. support establishing / renewing sessions after successful authentication and to authenticate from session based credentials like cookies etc.

Hopefully that will dovetail well with shelf_simple_session

I want! 👍 Moving from HttpServer and the http_server package to Shelf, and hit with the lack of cookie support, where before I was doing e.g. var sessionCookie = request.cookies.firstWhere((cookie) => cookie.name == 'session', orElse: () => null);.

Yeah would be nice if this one was prioritised

Is there any chance that this could be implemented soon?

This might be something we need the community to drive. @nex3 and I are both pretty slammed.

@kevmoo I would like to take a stab at this. Would having the ability to parse and set a cookie be good enough for a first PR?
