I have a few years worth of experience building Child Themes in WordPress, which is generally my preferred route when developing a new website as I am not a theme developer per say.
I am now doing a couple of projects which want to leverage the WP REST API, and I am looking to use the Foxhound theme, built using React js, as a parent theme.
Beyond the page template/css overloading approach to child theme-ing, I have been trying to understand how to extend the parent theme's default react app functionality to customise my child theme js functionality. I understand how to add custom fields to existing end-points, however, what I am not able to understand is how to load custom react components. Should I/Can I build a custom react app to load from my child theme? If so how can I ensure it executes after the parent theme app?
