Javascript / Jquery not working with Ruby on Rail 7?-CodePudding

Hi I'm new to RoR and I'm currently trying to implement some javascript / jquery code to my application but I can't seem to get it to work. I can't even seem to print out a simple "helloworld" into the console of my application when I click on a certain element or even print out a simple "hello" onto the console. I believe it may be some issue of my javascript code not being loaded with the application. Any help or guidance would be greatly appreciated.

app/assets/config/manifest.js

 //= link_tree ../images
//= link_directory ../stylesheets .css
//= link_tree ../../javascript .js
//= link_tree ../../../vendor/javascript .js

//= require scripts

app/javascript/application.js

// Configure your import map in config/importmap.rb. Read more: https://github.com/rails/importmap-rails
import "@hotwired/turbo-rails"
import "controllers"

//= require styles

app/javascript/controllers/application.js

import { Application } from "@hotwired/stimulus"

const application = Application.start()

// Configure Stimulus development experience
application.debug = false
window.Stimulus   = application

export { application }

app/controllers/index.js

// Import and register all your controllers from the importmap under controllers/*

import { application } from "controllers/application"

// Eager load all controllers defined in the import map under controllers/**/*_controller
import { eagerLoadControllersFrom } from "@hotwired/stimulus-loading"
eagerLoadControllersFrom("controllers", application)

// Lazy load controllers as they appear in the DOM (remember not to preload controllers in import map!)
// import { lazyLoadControllersFrom } from "@hotwired/stimulus-loading"
// lazyLoadControllersFrom("controllers", application)

app/javascript/posts.js

$(function(){

    $(".post-like").on("click", function(){
        console.log("hello")
    })
})

Thanks Oscar for the input, it led me to the right direction! You need to reference your javascript files using "data-controller="name of javascript controller". This video helped me implement javascript into my Ruby On Rails 7 Application. Hope this answers helps anyone else in the same boat as me.

Rails 7.0 using importmap as default, it work with import function.

you can just simply add import "./posts.js" in app/javascript/application.js and it should work!
