Realtime Notifications with ActionCable

In this episode we're going to be adding realtime notifications into your app using ActionCable. We've talked about notifications a few times in the past and we used AJAX polling for that. 95% of the time, polling is the solution that would be recommended for it.

But if you're looking for a good introduction into ActionCable then this is a decent one because we're only really using it for one way from the server side to the client side.

Getting started

So to get started we're starting with an app that has Bootstrap installed and then we created a Main controller with an index view which is where we will list our Notifications as for this example.

Before we generate our channels let's install a few things

	# frozen_string_literal: true

	require 'bundler/inline'

	gemfile do
	source 'https://rubygems.org'

	gem 'dotenv'
	gem 'ruby-openai'
	end

	# This is a thin wrapper of the Simple Form builder. It delegates rendering the resulting form fields to Simple Form
	# but typically amends the Tailwind classes of the various elements in the field layout. It tightly integrates with the
	# unstyled wrapper (aka `:plain`) Simple Form configuration (see `simple_form.rb`). The methods support the same syntax
	# as the original Simple Form methods but enhance it to support replacing defaylt Tailwind claseses.
	class Builders::TailwindFormBuilder < SimpleForm::FormBuilder

	# This is the basic method for rendering `<input>` tags and their variants.
	def input(attribute_name, options = {}, &block)
	# The default Tailwind classes for the various parts of the Simple Form wrapper layout.
	input_class = "block w-full sm:text-sm ... #{'text-gray-500 bg-gray-50' if options.dig(:input_html, :disabled)}"

	// Note: this gist is a part of this OSS project that I'm currently working on: https://github.com/steven-tey/dub

	export default async function getTitleFromUrl (url: string) {
	const controller = new AbortController();
	const timeoutId = setTimeout(() => controller.abort(), 2000); // timeout if it takes longer than 2 seconds
	const title = await fetch(url, { signal: controller.signal })
	.then((res) => {
	clearTimeout(timeoutId);
	return res.text();
	})

	sudo su
	//Setup Hostname
	hostnamectl set-hostname subdomain.domain.tld

	## Basic
	sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get autoremove -y && sudo apt-get install software-properties-common

	//Setup SWAP
	sudo fallocate -l 1G /swapfile;
	ls -lh /swapfile;
