Humming-Bird

Here be dragons: Humming-Bird is still young, you may run into bugs, creatures, and daemons, if you run into any issues, please make an issue!

Humming-Bird is a simple, composable, and performant, all in one HTTP web-framework for Raku. Humming-Bird was inspired mainly by Opium, Sinatra, and Express, and tries to keep things minimal, allowing the user to pull in things like templating engines, and ORM's on their own terms.

Humming-Bird comes with what you need to quickly, and efficiently spin up REST API's, and with a few of the users favorite libraries, dynamic MVC style web-apps.

Humming-Bird is not meant to face the internet directly. Please use a reverse proxy such as httpd or NGiNX.

Examples

Simple example:

use v6.d;

use Humming-Bird::Core;

get('/', -> $request, $response {
    $response.html('<h1>Hello World</h1>');
});

listen(8080);

# Navigate to localhost:8080!

Simple JSON example:

use v6;

use Humming-Bird::Core;

my %users = Map.new('bob', '{ "name": "bob" }', 'joe', '{ "name": "joe" }');

get('/users/:user', -> $request, $response {
    my $user = $request.param('user');

    if %users{$user}:exists {
        $response.json(%users{$user});
    } else {
        $response.status(404);
    }
});

listen(8080);

Middleware

use v6.d;

use Humming-Bird::Core;
use Humming-Bird::Middleware;

get('/logged', -> $request, $response {
    $response.html('This request has been logged!');
}, [ &middleware-logger ]); # &middleware-logger is provided by Humming-Bird::Middleware

# Custom middleware
sub block-firefox($request, $response, &next) {
    return $response.status(400) if $request.header('User-Agent').starts-with('Mozilla');
    $response.status(200);
}

get('/no-firefox', -> $request, $response {
    $response.html('You are not using Firefox!');
}, [ &middleware-logger, &block-firefox ]);

# Scoped middleware

# Both of these routes will now share the middleware specified in the last parameter of the group.
group([
    &get.assuming('/', -> $request, $response {
        $response.write('Index');
    }),

    &post.assuming('/users', -> $request, $response {
        $response.write($request.body).status(204);
    })
], [ &middleware-logger, &block-firefox ]);

Design

• Humming-Bird should be easy to pickup, and simple for developers new to Raku and/or web development.

• Humming-Bird is not designed to be exposed to the internet directly. You should hide Humming-Bird behind a reverse-proxy like NGiNX or httpd.

• Simple and composable via middlewares.

Things to keep in mind

• This project is in active development, things will break.

• You may run into bugs.

• Not production ready, yet.
