directory structure as in Laravel

I want to develop a project on flarum

But I need to work with the flarum as if I'm working with laravel and directory structure as in Laravel.

In the root directory, I need folders like:
app
config
resources
routes

and other.

Can you tell me how to get this?

Flarum is a Composer project. You can configure Composer to autoload classes from every directory structure you can imagine.

Franz beta8 for example ?
