Hakone PSR-15 middleware dispatcher 🏃‍♀️

Hakone is a lightweight PSR-15 middleware dispatcher implementation. It is inspired by Relay.

Concept

The PSR-15 is designed to be general purpose middleware. All middleware can intervene in both requests and responses.

Hakone is a "queue-based request handler" described in PSR-15 Meta Document. The downside of queue-based is that the more middleware you have, the more stack traces will pile up.

We've written a number of small-duty middlewares, but for many use cases they only do work on either the request or the response. We decided to classify the types of middleware into three types: "request interceptor", "general-purpose middleware" and "response decorator".

How to use

$dispatcher = Hakone\relay([
    'interceptors' => [
        // ...
    ],
    'middlewares' => [
        // ...
    ],
    'handler' => $handler
    'decorators' => [
        // ...
    ],
]);
