The macro should be

Builder::macro(
    'withWhereHas',
    function ($relation, $constraint) {
        return $this
            ->whereHas($relation, $constraint)
            ->with($relation, $constraint);
    }
);

if not using lambda

Thanks. I solved the same problem with inner join which supposed to be more performance efficient.

Hello! 👋
JOIN could has better performance than WHERE EXISTS (with - eager loading), BUT:

The reason to use WITH, is for accessing models as related objects (with all their fields) instead of access a couple of fields specified in JOIN.

Great, would you please share your Macro?

Thanks for sharing. Worthy to note that laravel now has withWhereHas eloquent method by default

Unlike in your case, where withWhereHas is a scope.

thanks for great article.
Now I know that with the withWhereHas() I can load the relationship with specific condition.

Hi Othmane Nemli, thanks for your article.
I have one doubt though, I didn't understand why you use the whereHas query if you just specified the condition in the first query.
Don't you get the desired result only with the "with" query+condition?

Thanks in advance

Thanks for reading the article.

Well, using same condition in with() and whereHas() is to prevent N+1 and get only data that you asked for in the whereHas(), so as I demonstrate the issue that we may face, the solution was to combine with() and whereHas() with same condition ..
