Inspired by cooking, allows the creation of dynamic algorithm, called here recipe, following the #east programming and using middleware, configurable via DI or any configuration, if a set of conditions (ingredients) are available.

Quick Example



use Teknoo\Recipe\Dish\DishClass;
use Teknoo\Recipe\Ingredient\Ingredient;
use Teknoo\Recipe\Recipe;
use Teknoo\Recipe\Chef;
use Teknoo\Recipe\ChefInterface;
use Teknoo\Recipe\Promise\Promise;

require 'vendor/autoload.php';

$recipe = new Recipe();

$recipe = $recipe->require(
    new Ingredient(\DateTime::class, 'date')

$recipe = $recipe->cook(
    function (\DateTime $date, ChefInterface $chef): void {
        $date = $date->setTimezone(new \DateTimeZone('UTC'));

        $chef->continue(['date' => $date]);

$recipe = $recipe->cook(
    function (\DateTime $date, ChefInterface $chef): void {
        $immutable = \DateTimeImmutable::createFromMutable($date);


$output = '';
$recipe = $recipe->given(
    new DishClass(
        new Promise(
            function (\DateTimeImmutable $immutable) use (&$output): void {
                $output = $immutable->format('Y-m-d H:i:s T');
            function (\Throwable $error) use (&$output): void {
                $output = $error->getMessage();

$chef = new Chef;
$chef->process(['date' => new \DateTime('2020-06-27 00:00:00', new \DateTimeZone('Europe/Paris'))]);

//Show : 2020-06-26 22:00:00 UTC
echo $output.PHP_EOL;

    • callable will be automatically wrapped by a fiber,
    • the fiber object will be available as parameter for bowls.
  • Add Fiber support to RecipeBowl, also in a dedicated class FiberRecipeBowl. The Fiber instance is also passed into workplan.
  • Add a CookingSupervisorInterface and its default implementation CookingSupervisor to manage Bowls Fibers executions and loop on each active fiber. CookingSupervisor are also available as parameter for bowls.

  • Add TransformableInterface and attribute Transform to allow transform an ingredient before to put it into the bowl

News from Teknoo Recipe 3.0

This library requires PHP 8.0 or newer. Some change causes bc breaks.

  • Promise immutable check is performed before var assignment
  • Some optimisations on array functions to limit O(n)
