Question 1

How to set up pjax with Ruby on Rails?

Accepted Answer

In Rails, detect pjax requests via the X-PJAX header in controllers and render views without the layout (e.g., render layout: false). The README provides a code example for this, allowing partial content delivery to optimize performance.

Question 2

pjax vs Turbolinks: which should I use?

Accepted Answer

pjax offers more control with event hooks and partial updates, while Turbolinks is more automated but less customizable. However, Turbolinks is better maintained for Rails, whereas pjax is unmaintained but works with any server framework.

Question 3

How to handle JavaScript reinitialization after pjax updates?

Accepted Answer

Bind plugin reinitialization to events like pjax:end, as shown in the README, using $(document).on('ready pjax:end', function(event) { $(event.target).initializeMyPlugin(); }) to ensure plugins work on new content.

Question 4

Does pjax work with forms?

Accepted Answer

Yes, pjax supports form submissions via $.pjax.submit, allowing AJAX-based form handling with URL updates, but it requires annotating forms with data-pjax and server-side configuration for partial responses.

Question 5

What happens when pjax requests fail or timeout?

Accepted Answer

By default, pjax forces a full page reload on errors or after a timeout (default 650ms), but you can cancel this via events like pjax:timeout to implement custom fallback behavior, as detailed in the events table.
