HTTP::Server::Router zef:tony-o last updated on 2021-02-15

Perl6's HTTP Router for the Pros

This here module provides a routing system for use with HTTP::Server::Async. It can accept named parameters (currently no restraints on what the parameter is), and hard typed paths. Check out below for examples and usage.

Usage

use HTTP::Server::Async;
use HTTP::Server::Router;

my HTTP::Server::Async $server .=new;

serve $server;

route '/', sub($req, $res) {
  $res.close('Hello world!');
}

route '/:whatever', sub($req, $res) {
  $res.close($req.params<whatever>);
}

route / .+ /, sub($req, $res) {
  $res.status = 404;
  $res.close('Not found.');
}

$server.listen(True);

The example above matches a route '/' and response 'Hello world!' (complete with headers). The other route that matches is '/' and it echos <anything> back to the client. All other connections will hang until the client times them out.

Notes

Routes are called in the order they're registered. If the route's sub returns a promise, no further processing is done until that Promise is kept/broken. If the route's sub does not return a Promise then a True (or anything that indicates True) value indicates that further processing should stop. A False value means continue trying to match handlers.

Do what you will. Be careful out there amongst the English.
