'How to import Tailwind plugin in Rails 7

I'm trying to use npm package 'tailwindcss-flip' in my Rails 7 app. The package docs have the following instructions:

Install tailwindcss-flip package:

Install using NPM

npm install tailwindcss-flip --save-dev

Install using Yarn

yarn add tailwindcss-flip --dev

Add plugin to your tailwind.conf.js file: plugins: [require("tailwindcss-flip")]

My question is, I did pin the package in importmap, but I got the following error:

Error: Cannot find module 'tailwindcss-flip'

Any idea how this can work in Rails 7 (No Webpacker).

I assume you're using tailwindcss-rails gem. That is the default even if you run rails new app --css tailwind. It uses standalone tailwind executable https://tailwindcss.com/blog/standalone-cli which comes bundled with first party plugins. So any plugin in @tailswindcss/* should work out of the box.

To use any other tailwind plugins you must run a full node.js version of tailwind. The Rails 7 way is to use cssbundling-rails.

# Gemfile
# remove gem 'tailwindcss-rails'
gem 'cssbundling-rails'

bin/bundle install
bin/rails css:install:tailwind

Add build script to package.json

  "scripts": {
    "build:css": "tailwindcss -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css --minify"
  },

Add any plugin you like after that. In your case:

yarn add tailwindcss-flip --dev

Add plugins to tailwind config. By default it is tailwind.config.js (standalone tailwindcss-rails version uses config/tailwind.config.js which you don't need anymore)

  plugins: [
    require("tailwindcss-flip"),
  ],

In your layout you should only have application stylesheet. Remove stylesheet_link_tag "tailwind"

<%= stylesheet_link_tag "application", "data-turbo-track": "reload" %>

To start compiling your css, run the build script from package.json

yarn build:css --watch

This should output app/assets/builds/application.css file. It is served by rails asset pipeline (sprockets). In case you get sprocket errors, restart everything, clear cache, check app/assets/config/manifest.js to include //= link_tree ../builds.

There's another option if you want to use importmap.

1 - pin required libs

$ ./bin/importmap pin tailwindcss-flip

2 - add following code to your layout file in head section

    <script>
      tailwind.config = {
        plugins: [
          require('@tailwindcss/typography'),
          require("tailwindcss-flip"),
        ],        
      }      
    </script>

3 - just use dir=rtl in your views

4 - PROFIT!!! :)
