I have added this to my functions.php and need to use ajaxURL in all of enqueued scripts in the template (instead of enqueuing only one script here

add_action( 'wp_enqueue_scripts', 'ajaxify_enqueue_scripts' );

function ajaxify_enqueue_scripts() {

   wp_localize_script( 'ajaxify', 'ajaxURL', array('ajax_url' => get_template_directory_uri() . '/app/login.php' ));

}

add_action( 'wp_ajax_nopriv_set_ajaxify', 'set_ajaxify' );

add_action( 'wp_ajax_set_ajaxify', 'set_ajaxify' );

but when I try to call an ajax method I am getting this error

Uncaught ReferenceError: ajaxURL is not defined

Is there any way to add the ajaxURL to all scripts?

You can conditionally echo the code on only few templates or specific pages. Here is an example:

add_action ( 'wp_head', 'my_js_variables' );

function my_js_variables(){

  // for specific page templates

  $current_template =  get_page_template();



  // return if there is no page template, or if the page template is other than template-x1.php or template-x2.php

  if( !isset($current_template) || ( $current_template != 'template-x1.php' && $current_template != 'template-x2.php' ) ){ return; } ?>

  <script type="text/javascript">

    var ajaxurl = <?php echo json_encode( admin_url( "admin-ajax.php" ) ); ?>; 

    var ajaxnonce = <?php echo json_encode( wp_create_nonce( "itr_ajax_nonce" ) ); ?>;

    var myarray = <?php echo json_encode( array(

         'foo' => 'bar',

         'available' => TRUE,

         'ship' => array( 1, 2, 3, ),

       ) ); ?>

  </script>

<?php

}

To have the ajaxurl variable available on the frontend the easiest way is to add this snippet to you theme’s function.php file:

add_action('wp_head', 'myplugin_ajaxurl');

function myplugin_ajaxurl() {

    echo '<script type="text/javascript">

           var ajaxurl = "' . admin_url('admin-ajax.php') . '";

         </script>';

}

This get the url of the ajax submission page and creates a variable in the head of the HTML with it. Now ‘ajaxurl’ is available in your theme so you can start making it more modern and dynamic.
