[Vuejs]-Show message after submit data using laravel and vue.js

It’s good to pass response as JSON Format

YourXYZController.php
....
$data = new stdClass;
$data->status = "success";
$data->message = "your message";

return response(json_encode($data));

in Vuejs

axios.post('YourXYZController URL', params)
        .then(response => {
          console.log(response)
        })
        .catch(error => {
          console.log(response)
        })
    })

And also it’s best practice to check request and response in network tab of browser.
