How to return html file as symfony response?

To return an HTML file as a Symfony response, you can use the render() method provided by the Symfony Twig bundle. Here's an example of how you can do this in a Symfony controller:

use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyComponentHttpFoundationResponse;

class YourController extends AbstractController
{
    public function yourAction()
    {
        $html = $this->render('path/to/your/template.html.twig');

        return new Response($html, Response::HTTP_OK, ['Content-Type' => 'text/html']);
    }
}

In this example, replace 'path/to/your/template.html.twig' with the actual path to your HTML template file. The render() method will load and render the HTML template file, and then you can return it as a Symfony Response object with the appropriate content type.

Make sure to have the Twig bundle installed in your Symfony project, as it is used by default for rendering templates.
