Modern Front-End Development for Rails: Setting-up Intro, Chapter 1 and 2

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.

First Post!
