Using Stimulus JS to POST

Whenever you use pagy links that require interception, you will need to reinitialise any javascript that you need to run. If you submit a form, and use a turbo frame to render those search results, and to also render the pagination links to those results, how are you going to reinitialize your javascript code to intercept those pagy page links?

Stimulus JS is very handy for reinitialising javascript code, and is useful if you are using a library like hotwire (by Basecamp) where changes are made to the DOM.

// pagy_controller.js - a stimulus JS controller
import { Controller } from "@hotwired/stimulus"

# objc[18501]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

# I had this problem when running `bin/rails c` on Mac M1 Pro. The solution for this is below

$ export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
$ export DISABLE_SPRING=true

This should help.
