[dancer-users] Running a bot as a REST webservice

Hi, I'm making a bot. I'm trying to integrate it into a Dancer2 app, in
order to make a REST API for it, and later be able to interact with it from
the browser.
It logs in to an external webservice, like this:
$bot->login($username, $password);
This stores some credentilals in the bot, which uses them for other
requests.
And then it does some other stuff:
$->do_stuff;
The bot exists and can make these very basic operations from a script.
To create the REST API with Dancer2, I made something in those lines:
my $bot = MyBot->new;
post '/login.json' => sub {
my ($username, $password) = (params->{username},
params->{password});
$bot->login($username, $password); # Store credentials in the bot
};
This works perfectly.
And then
post '/do_stuff.json' => sub {
$bot->do_stuff;
}
This doesn't work: when I call '/login.json', followed by '/do_stuff.json',
the second request fails because the credentials are not present: it seems
to not be interacting with the same $bot object than the login request.
It works if add
$bot->login( ... )
at the beginning of the '/do_stuff.json' subroutine, but I don't want to
login at each new request.
What is a clean solution for this use case?

I have found Dancer2::Plugin::Adapter<https://metacpan.org/pod/Dancer2::Plugin::Adapter>and
the "singleton" scope, which seems to be what I need. But it won't
install. I will send a RT ticket.
Any idea for an alternative solution?
