this gem is not compatible with turbolinks

[killernova]

When use turbolinks, consider clicking the 'next page' button of a list for several times, the trigger of post '/active' will repeat for this times. e.g. I auto_session_timeout_js frequency: 120, and then click 'next page' for 5 times, then every 120 seconds will post to /action for 5 times. That's caused by write the codes in body. The correct way to do is wrapping the codes in $('document').on('turbolinks:load', function(){}).

@killernova you should be able to add an ignore attribute for turbolinks when https://github.com/pelargir/auto-session-timeout/pull/18 is merged in, please have a look at the added test case

[killernova]

@emilos Yes, I've noticed this PR many days ago, but I've written some codes to replace the auto_session_timeout_js method to make the gem work with turbolinks before this pr posted. I'll try it another day with the new method. Thanks.

@killernova #18 has been merged. Does that fix your problem?

[davegudge]

I can confirm this is still a problem when Turbolinks is enabled. Replicated by logging in and clicking a few times. A request to /active is trigger per click as outlined in the log output below when the browser is sitting idle:

[pelargir]

I'll try reproducing this when I have time. If anyone wants to submit a PR fix in the meantime, please do.

[pelargir]

I was able to reproduce this problem and am working on a fix.

If someone else has this problem too, this may help with Turbo and Stimulus.

On every page change, stimulus calls the disconnect function, where the already running function is stopped.

Important: Do not use auto_session_timeout_js at the same time! Remove auto_session_timeout_js from your view if already inserted.

rails g stimulus AutoSessionTimeout

Content of app/javascript/controllers/auto_session_timeout_controller.js:

import { Controller } from "@hotwired/stimulus"

// Connects to data-controller="auto-session-timeout"
export default class extends Controller {

  initialize() {
    this.intervalId = 0;
    this.frequency = Number(this.element.dataset.astFrequency) || 60;
    this.active_path = String(this.element.dataset.astActivePath)
    this.timeout_path = String(this.element.dataset.astTimeoutPath)

    super.initialize();
  }

  connect() {
    if (this.active_path === 'undefined') {
      console.log('auto-session-timeout message:')
      console.log('ast-active-path is not defined - value: ' + this.active_path);
      return;
    }

    if (this.timeout_path === 'undefined') {
      console.log('auto-session-timeout message:')
      console.log('ast-timeout-path is not defined - value: ' + this.timeout_path);
      return;
    }

    this.intervalId = setInterval(this.check_timeout.bind(this), (this.frequency * 1000));
  }

  disconnect() {
    clearInterval(this.intervalId);
  }

  check_timeout() {
    const timeout_path = this.timeout_path                                                                                                                                                                         
    const request = new XMLHttpRequest();
    
    request.onload = function(event) {
      var status = event.target.status;
      var response = event.target.response;
      
      if (status === 200 && (response === false || response === 'false' || response === null)) {
        window.location.href = timeout_path;
      }
    };
    
    request.open('GET', this.active_path, true);
    request.responseType = 'json';
    request.send();
  }
}

And in app/views/layouts/application.html.slim:

[...]
- ast_values = user_signed_in? ? { data: { controller: 'auto-session-timeout', 'ast-frequency': 15, 'ast-active-path': "#{active_path}", 'ast-timeout-path': "#{timeout_path}" } } : {}

body *ast_values
[...]

Additionally, I had to adjust protect_from_forgery in application-controller.rb

  # Timeout sessions
  auto_session_timeout

  #has to be after auto_session_timeout so that prepend will not be overwritten.
  protect_from_forgery with: :exception, prepend: true
