This took me too much to figure out from different sources hence jotting down my recipe.
My application is called ADA ... here the main part with login / logout
package Ada;
use Dancer2;
use Dancer2::Session::Simple;
use Dancer2::Plugin::Auth::Tiny;
our $VERSION = '0.1';
# Authentication Requires Session, here the in memory
set session => "Simple";
#set session => 'YAML';
hook before => sub {
printf "logged in? %s\n", session('user') ? session('user') : '-';
if ( !session('user') && request->dispatch_path !~ m{^/login} ) {
forward '/login', { requested_path => request->dispatch_path };
}
};
get '/' => sub {
template 'index';
};
get '/login' => sub {
# Display a login page; the original URL they requested is available as
# param('requested_path'), so could be put in a hidden field in the form
template 'login', { path => param('requested_path') };
};
post '/login' => sub {
if ( _is_valid( param('user'), param('pass') ) ) {
print "logged on success!\n";
session user => param('user');
redirect param('path') || '/';
}
else {
redirect '/login?failed=1';
}
};
sub _is_valid {
my ( $u, $p ) = @_;
my $store = schema 'default';
foreach my $r ( $store->resultset('PmiUser')->all ) {
printf "%10s = %s\n", $r->fedex_id, $r->fedex_pw;
}
my $rec =
$store->resultset('PmiUser')
->find( { 'id' => $u, 'pwd' => $p } );
printf $rec->fedex_id;
return $rec and $rec->fedex_id ? 0 : 1;
}
get '/logout' => sub {
printf( "logging out %s\n", session('user') ? session('user') : '-' );
context->destroy_session;
redirect '/';
};
true;

Add the Logout function to your navigation pills.... make sure its a href.
<!-- Add your site or application content here -->
<div class="header">
<ul class="nav nav-pills pull-right">
<li class="active"><a ng-href="#">Home</a></li>
<li><a href="./logout">Logout</a></li>
</ul>
<h3 class="text-muted">AD Assistant</h3>

login.tt
A very simple ugly login screen.
<html>
<head>
<title>Session and logging in</title>
</head>
<body>
<form action='/login' method='POST'>
User Name : <input type='text' name='user'/>
Password: <input type='password' name='pass' />
<!-- Put the original path requested into a hidden
field so it's sent back in the POST and can be
used to redirect to the right page after login -->
<input type='hidden' name='path' value='[% path %]'/>
<input type='submit' value='Login' />
</form>
</body>
