leobm / plack_server.pl
Created May 5, 2026 15:49
Using HTTP::Server::PSGI and Plack, you can build something like this.
use strict;
use warnings;
use HTTP::Server::PSGI;
use Plack::Request;
use Plack::Response;
my $app = sub {
my $env = shift;
my $req = Plack::Request->new($env);

Here's perhaps a slightly more comprehensive interface of how it could be built
use strict;
use warnings FATAL => 'all';
# The Request object ($req)
# - method(): Returns GET, POST, etc.
#
# - path(): The path itself (e.g., /user/profile).
#
# - query($key): Extracts values from the query string after the ?.
