How to Install TailwindCSS with Webpacker in Ruby on Rails

Setting up a modern web project can often be a daunting task, especially when integrating different technologies. One common setup many developers are looking for is how to install TailwindCSS, a utility-first CSS framework, using Webpacker in a Ruby on Rails application. If you've found yourself struggling to get this integration right, you're not alone. Many guides out there are outdated and can lead to errors such as improperly loading styles or encountering Webpacker errors.

In this guide, we'll walk you through the process of installing TailwindCSS with Webpacker in Rails step by step, ensuring you have a smooth experience without complications.

Getting Started

Before we dive into the installation process, make sure your Rails application has Webpacker set up correctly. If you're starting anew, create a new Rails application with the following command:

This command creates a tailwind.config.js file where you can customize your TailwindCSS settings.

Step 3: Update PostCSS Configuration

Next, you'll need to configure PostCSS to use TailwindCSS. Open the postcss.config.js file in your Rails project and make sure it includes tailwindcss. It should look like this:

This configuration tells PostCSS to use both the tailwindcss and other necessary plugins.

Step 4: Import TailwindCSS in SCSS

Next, you'll want to load TailwindCSS styles into your application. Create a file named application.scss (if it doesn't exist already) inside the app/javascript/css/ directory. Add the following imports to this file:

These imports bring in the core styles, components, and utility classes provided by TailwindCSS.

Step 5: Update Your JavaScript Pack

Finally, you need to inform your application to use the compiled CSS. Open the app/javascript/packs/application.js file and include the following line:

This line ensures that your SCSS containing TailwindCSS styles is included in your JavaScript pack.

Wrapping Up

That’s it! You've successfully installed TailwindCSS with Webpacker in your Ruby on Rails application. Following these steps, you should now be able to utilize all the fantastic features of TailwindCSS without running into the issues that plagued many prior attempts found in outdated guides.

Summary
