FCGI SAPI host for dispatch of PSR-15 Handler

0.6.1 2021-02-25 10:55 UTC


This library implements a SAPI host for dispatch of PSR-15 HandlerInterface.

This project is work in progress.

Originally a fork of Daniel Bannert's narrowspark/http-emitter package, this package takes a different approach, internally leveraging Tobias Nyholm's nyholm/psr7-server package to bootstrap the incoming PSR-7 Request.

The philosophy of this package is that hosting a single handler, for a single request, should be a single operation.


To bootstrap a SapiHost, you need to pick a PSR-7 and PSR-17 implementation - for example, nyholm/psr7-server supports both, and you can install it with:

composer require nyholm/psr7-server

You need to have your PSR-15 handler implementation to dispatch, and then, for example, dispatch it from an index.php file, as follows:


use Kodus\Http\SapiHost;
use Nyholm\Psr7\Factory\Psr17Factory;

$factory = new Psr17Factory();

$host = new SapiHost(

$host->dispatch(new YourRequestHandler());

Note that Psr17Factory implements all of the required PSR-17 factory interfaces.
