Install

No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:

wp plugin install https://github.com/westonruter/script-modules-in-footer/archive/refs/heads/main.zip

Declares an update source (https://github.com/westonruter/script-modules-in-footer), so updates arrive through the plugin's own updater.

Script Modules in Footer

Contributors: westonruter

Stable tag: 0.1.0

Description

Prints script modules at wp_footer instead of at wp_head to improve performance by reducing network contention for the critical rendering path. This can be used with Script Fetch Priority Low to improve performance even more. This is only relevant for block themes.

This is a prototype for #63486 in WordPress core to test the performance impact.

Important: This moves all script modules to the footer. In WordPress core, script modules are used exclusively for the Interactivity API which uses server-side rendering, so they are safe to deprioritize by moving to the footer. However, if you have any script modules that are in the critical rendering path then you shouldn't use this plugin.

See full writeup: Improve LCP by Deprioritizing Script Modules from the Interactivity API.
