Is this book still relevant because setting it up could well be more difficult with newer gems/packages than when you first wrote the book. There is a reason why I haven’t touched the book in almost a year.

Intro:

%bin/setup -> NOK 

Needs dummy.ts in app/packs/entrypoints

Chapter 1:

%yarn add css-loader mini-css-extract-plugin css-minimizer-webpack-plugin -> OK %yarn add postcss-loader sass sass-loader -> OK %yarn add tailwindcss@latest postcss@latest autoprefixer@latest -> NOK TypeError: Cannot read property '700' of undefinedType Error: Cannot read property '700' of undefined ....node_modules/@tailwindcss/typography/src/styles.js:16:65 

To overcome this error I chose the last major version and it worked. I really don’t want to see upto which version 3 it breaks at

%npm show tailwindcss versions %yarn add tailwindcss@2.2.19 postcss@latest autoprefixer@latest -> OK %yarn add @tailwindcss/forms -> OK %npx tailwindcss init -> OK 

Page 10 - app/javascript/packs/application.scss should be app/packs/entrypoints/application.scss

%yarn add typescript @babel/preset-typescript -> OK 

Chapter 2:

%rails hotwire:install -> NOK Create controllers directory create app/javascript/controllers create app/javascript/controllers/index.js create app/javascript/controllers/application.js create app/javascript/controllers/hello_controller.js Couldn't find "app/javascript/application.js". You must import "./controllers" in your JavaScript entrypoint file Install Stimulus run yarn add @hotwired/stimulus from "." You must import @hotwired/turbo-rails in your JavaScript entrypoint file Install Turbo run yarn add @hotwired/turbo-rails from "." %less config/webpacker.yml default: &default source_path: app/packs source_entry_path: entrypoints 

Not sure why it’s installing into app/javascript/controllers and can’t find application.js but I’m not an expert on JS stuff hence reading this book. Trying to read this book.

In the book, there are:
32 references to app/packs/controllers
1 reference to app/javascript/controllers → this is a typo, no?

%less app/packs/entrypoints/application.js import "channels" import "core-js/stable" import "regenerator-runtime/runtime" import * as ActiveStorage from "@rails/activestorage" import Rails from "@rails/ujs" import Turbolinks from "turbolinks" Rails.start() Turbolinks.start() ActiveStorage.start() 

app/packs/entrypoints/application.js file hasn’t changed

I’ve given up unless I have done something bleeding obviously wrong.
