Friendly URL for a custom component

Question

I'm trying to create a friendly URL for a custom component but i can't manage to find a solution. I have tried JRoute but it hasn't worked out for me (probably i'm not doing it right). Does anybody have any idea? I have created the router file and i read the documentation but i couldn't understand.

place?id=113?cat=3

i wanted it to be

place/113/3

UPDATE:

after implementing all methods i get the following error:

Argument 1 passed to ComponentRouter::__construct() must be an instance of CMSApplication or null

My code is:

class ContentRouter implements Joomla\CMS\Component\Router\RouterInterface

{   

    public function __construct(CMSApplication $app = null, AbstractMenu $menu = null)
    {
        $category = new RouterViewConfiguration('category');
        $category->setKey('id')->setNestable();
        $this->registerView($category);
        $article = new RouterViewConfiguration('article');
        $article->setKey('id')->setParent($category, 'catid');
        $this->registerView($darticle);

        parent::__construct($app, $menu);

        $this->attachRule(new MenuRules($this));
        $this->attachRule(new StandardRules($this));
        $this->attachRule(new NomenuRules($this));
    }

    /* the other methods go here

}

I'm not sure if Joomla\CMS\Component\Router\RouterInterface is the right class to be implement since there's no many examples but i followed along with the tutorial, i have implemented all the 3 methods and i yet get that error.

You have to create a router for your component for JRoute::_() to do anything. See Supporting SEF URLs in your component documentation. I suggest looking specifically at Simple View-based Example which uses a new way of working with routing.
