RenderView in Symfony Helper usage

Question

How can I use $this->renderView inside a Symfony helper class (not inside a controller)? I'm new about the function renderView but what do I have to setup to use it within the Helper class?

Answer 1

You can inject twig as a service with autowiring

<?php

namespace App\My\Ns;

use Twig\Environment;

class Helper
{
    public function __construct(
        protected Environment $environment
    ) {
    }

    public function method()
    {
        $html = $this->environment->render('my/template.html.twig', [/*  vars */]);
    }
}
