You can write it globally like below.

Normal JS:

$(function(){

    $('#loader').hide()
    $(document).ajaxStart(function() {
        $('#loader').show();
    })
    $(document).ajaxError(function() {
        alert("Something went wrong...")
        $('#loader').hide();
    })
    $(document).ajaxStop(function() {
        $('#loader').hide();
    });
    $.ajaxSetup({
        beforeSend: function(xhr) {xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))}
    });
});

Coffee Script:

  $('#loader').hide()
  $(document).ajaxStart ->
    $('#loader').show()

  $(document).ajaxError ->
    alert("Something went wrong...")
    $('#loader').hide()

  $(document).ajaxStop ->
    $('#loader').hide()

  $.ajaxSetup {
    beforeSend: (xhr) ->
      xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))
  }
