How to create authentication by React Native with Laravel

I'm trying to create login function with react native and laravel.

Code

public function logIn(Request $request)
    {
        if (Auth::attempt(['email' => $request['email'], 'password' => $request['password']], Auth::getRecallerName())) {
            $status = 200;
        } else {
            $status = 400;
        }
        return response()->json($status);
    }

authPost = async() => {
    axios
      .post(baseApiUrl + '/api/logIn', {
        email: this.state.email,
        password: this.state.password
      })
      .then((res) => {
        if(res.status === 200){
          this.props.navigation.navigate('Home');
        }else{
          console.log('failed');
        }
      })
      .catch(error => console.log(error));
  }

This code is working.

I wanna make sure if a user has already logged in or not.

I would appreciate it if you could give me any advice.
