@baris tks u very much, now code works.

Let add this to the plugin docs.

So now after activating my plugin and restarting nodebb, nodebb.min.js contains only one line: undefined, always in production mode and sometime in dev mode.

Is there something wrong with my client code that it made the build failed ? It pass through airbnb style guide, and used to work as expected

It's here:

$(document).ready(function () {
  'use strict';

  $(window).on('action:ajaxify.end', function () {
    // console.log(info);
    $('#autoduc-button').click(function () {
      $('#autoduc-dialog').modal();
    });

    $('#autoduc-send').click(function () {
      const url = $('#autoduc-url').val();
      // console.log(url);
      $.post('/api/autoduc', {
        url: url,
        cid: ajaxify.data.cid,
      }, function success(data) {
        const tid = data.tid;
        if (tid) {
          ajaxify.go('topic/' + tid);
        } else {
          app.alert({
            alert_id: 'autoduc-failed',
            type: 'danger',
            title: 'Failed',
            message: 'Post not found',
          });
        }
      });
    });
  });
});

Nodebb: 1.5.2
Node: 6.11.2

Thanks in advance.
