A "real" microframework that fits in just 4 lines of code.
The microframeworks out there weren't micro enough for me, so I brushed up on some of my code golfing skills to create µ.
These 4 LOC come jam-packed with features!
Follows the well-established route-to-callable microframework pattern.
echo (new µ) ->get('/hello', function ($app) { return "<p>Hello, world!</p>"; }) ->run();Allows you to access parameters from the URL.
echo (new µ) ->get('/hello/(?<name>\w+)', function ($app, $params) { return "<p>Hello, {$params['name']}!</p>"; }) ->run();Supports all your favorite HTTP verbs.
echo (new µ) ->delete('/user/(?<id>\d+)', $fn) ->get('/user/(?<id>\d+)', $fn) ->head('/user/(?<id>\d+)', $fn) ->patch('/user/(?<id>\d+)', $fn) ->post('/users', $fn) ->put('/user/(?<id>\d+)', $fn) ->run();Supports wildcard verbs too, because sometimes you are just making a web page and you really don't care about esoteric HTTP practices.
echo (new µ) ->any('/', $fn) ->run();use Monolog\Logger; use Monolog\Handler\StreamHandler; echo (new µ) ->cfg('log.channel', 'your-app') ->cfg('log.handler', function ($app) { return new StreamHandler('path/to/your.log', Logger::WARNING); }) ->cfg('log', function ($app) { $log = new Logger($app->cfg('log.channel')); $log->pushHandler($app->cfg('log.handler')); return $log; }) ->get('/hello/(?<name>\w+)', function ($app, $params) { $app->cfg('log')->addDebug("Said hello to {$params['name']}."); return "<p>Hello, {$params['name']}!</p>"; }) ->run();See previous example (I'm lazy).
Templates are just PHP files—no mustaches and no frills.
<!-- templates/hello.php --> <html> <head> <title>World Greeter</title> </head> <body> <p><?= ucfirst($greeting) ?>, <?= $name ?>!</p> </body> </html>// index.php echo (new µ) ->cfg('Ʋ', __DIR__ . '/templates') ->any('/hello/(?<name>\w+)', function ($app, $params) { return $app->ʋ('hello', [ 'greeting' => 'howdy', 'name' => $params['name'], ]); }) ->run();No twigs, plates, or blades to cut you or poke you.
Don't use this in production, or really anywhere. It's just for fun. 😄
