Answer 1

You could create a custom class that passes all functions to the DB facade exept your custom queries. Like this:

exitCalls = ['get', 'find', 'pluck', 'first', 'value', 'chunk', 'chunkById', 'count', 'max', 'avg', 'exists', 'doesntExist'];
    }

    public function __call($name, $arguments)
    {
        $result = call_user_func_array([self::$instance->db, $name], $arguments);

        if (in_array($name, $this->exitCalls)) {
            return $result;
        }

        return self::$instance;
    }

    public static function table($string)
    {
        if (self::$instance == null) {
            self::$instance = new CustomDB();
        }

        self::$instance->db = DB::table($string);

        return self::$instance;
    }

    public function myCustomQuery()
    {
         self::$instance->db->where('name','=','frank');
         return self::$instance;
    }
}

Now you can simply call:

CustomDB::table('users')->myCustomQuery()->get();
