2.2.7

Typed Workflow State

This release supports the ability to use custom workflow state class, so you can work with strictly typed properties.

Create your state class extending the default WorkflowState:

use NeuronAI\Workflow\WorkflowState;

class CustomState extends WorkflowState
{
    public string $custom = 'custom property';
}

Use this custom state as input type of the nodes __invoke mthod:

class MyNode extends Node 
{
    public function __invoke(StartEvent $event, CustomState $state): StopEvent
    {
        echo $state->custom;

        return new StopEvent();
    }
}

Finally start the Workflow passing the custom state instance. It will be propagated through the nodes:

$workflow = Workflow::make(new CustomState())->addNode($node);
$state = $workflow->start()->getResult();
