How To Async Or Defer JS In Liquid?

- 1 answer

I'm trying to improve site speed, and one thing that might be delaying render are these scripts:

  {{ '//' | script_tag }}
  {{ 'jGestures.min.js' | asset_url | script_tag }}
  {{ 'modernizr.min.js' | asset_url | script_tag }}

How can they be made to asych or defer? Or should I simply move them to the bottom? Also I have not made changes like this to my theme yet. Is it easy to revert changes in Shopify? I would just change it to the way it was before if any of the scripts were needed for the initial render, correct?

Edit: those scripts are in the HEAD section.



You have to do it little differently.

<script src="//" async></script>

<script src="{{ 'jGestures.min.js' | asset_url }}" async></script>

Make sure you copy/download the theme so that you have a backup. also shopify stores revisions so that you can revert back.
