How to Master Tailwind CSS Plugin Development in Your Next.js Projects: A Comprehensive Guide

In this blog post, we will discuss the importance and advantages of creating your own Tailwind CSS plugins and demonstrate how to create a simple plugin in a Next.js project.

Introduction

Tailwind CSS is a popular utility-first CSS framework designed to make it easy to style modern applications. By utilizing Tailwind CSS plugins, you can extend the framework’s functionality and make your codebase more consistent and maintainable.

Why create your own Tailwind CSS plugins?

There are several reasons why you may want to create your own Tailwind CSS plugins:

  1. Consistency: Custom plugins allow you to define a set of styles that can be reused across your application. This ensures that your design remains consistent, making it easier to manage and maintain.
  2. Customization: Plugins enable you to create your own utility classes that are tailored to your project’s specific needs. This allows you to add custom functionality to Tailwind CSS without having to write repetitive, inline styles.
  3. Reusability: Once you have created a plugin, you can easily share it with other projects or even publish it for the community to use. This promotes reusability and helps you maintain a consistent design system across multiple projects.
  4. Efficiency: Writing custom plugins allows you to define complex styles and behaviors with simple utility classes. This can make your code more readable and easier to understand, increasing your team’s productivity and efficiency.

With these benefits in mind, let’s dive into creating a custom Tailwind CSS plugin in a Next.js project.

Step 1: Set up the Next.js project

First, let’s create a new Next.js project using the following command:

npx create-next-app customPlugin
//change directory
cd customPlugin

Step 2: Install Tailwind CSS

Now, let’s install Tailwind CSS and its dependencies:

npm install -D tailwindcss@latest postcss@latest autoprefixer@latest

Create a configuration file for Tailwind CSS:

npx tailwindcss init -p

This command will create a tailwind.config.js and a postcss.config.js file in your project directory.

Step 3: Configure Tailwind CSS

Open tailwind.config.js and add the plugin configuration:

module.exports = {
  purge: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}'],
  darkMode: false,
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [require('./plugins/loading-indicator')],
}

Step 4: Create the loading-indicator plugin

Create a new directory called plugins:

mkdir plugins
//Create a new file called loading-indicator.js inside the plugins directory:
touch plugins/loading-indicator.js

Open the loading-indicator.js file and add the following code:

const plugin = require('tailwindcss/plugin')

module.exports = plugin(({ addUtilities }) => {
  const loadingUtilities = {
    '.loading-indicator': {
      display: 'inline-block',
      border: '2px solid transparent',
      borderTop: '2px solid currentColor',
      borderRadius: '50%',
      width: '24px',
      height: '24px',
      animation: 'spin 1s linear infinite',
    },
  }

  addUtilities(loadingUtilities, ['responsive'])
})

This plugin creates a .loading-indicator utility class that styles a loading spinner.

Step 5: Include Tailwind CSS in your project

Open the styles/globals.css file and replace its content with the following:

@tailwind base;
@tailwind components;
@tailwind utilities;

@keyframes spin {
  to {
    transform: rotate(360deg);
  }
}

Make sure to import styles/globals.css in your _app.js or _app.tsx file:

import '../styles/globals.css'

function MyApp({ Component, pageProps }) {
  return <Component {...pageProps} />
}

export default MyApp

Step 6: Use the plugin in a component

Create a new component called PageList.js:

import { useState, useEffect } from 'react'


const MOCK_DATA = [
    { id: 1, title: 'Page 1' },
    { id: 2, title: 'Page 2' },
    { id: 3, title: 'Page 3' },
]
const PageList = () => {
  const [pages, setPages] = useState([])
  const [loading, setLoading] = useState(true)

  useEffect(() => {
    fetchPages()
  }, [])

  const fetchPages = async () => {
    // mock api call to and to show spinner for two seconds
    const data = await new Promise((resolve) => {
        setTimeout(() => {
            resolve(MOCK_DATA)
        }, 2000)
    })
    setPages(data)
    setLoading(false)
  }

  return (
    <div>
      {loading ? (
        <div className="loading-indicator"></div>
      ) : (
        <ul>
          {pages.map((page) => (
            <li key={page.id}>{page.title}</li>
          ))}
        </ul>
      )}
    </div>
  )
}

export default PageList

In this component, we fetch a list of pages and display them. While the pages are being fetched, we show a loading spinner using the .loading-indicator utility class from our plugin.

Step 7: Add the PageList component to your application

Finally, let’s use the PageList component in the index.js file:

import Head from 'next/head'
import PageList from '../components/PageList'

export default function Home() {
  return (
    <div>
      <Head>
        <title>My Next App</title>
        <link rel="icon" href="/favicon.ico" />
      </Head>

      <main>
        <h1 className="text-2xl font-bold">List of Pages</h1>
        <PageList />
      </main>
    </div>
  )
}

Now, run the development server:

npm run dev

Open your browser and navigate to http://localhost:3000. You should see the loading spinner while the list of pages is being fetched, and the list of pages once the data is loaded.

That’s it! You have successfully created a Next.js project with Tailwind CSS and implemented a simple plugin to style loading elements.

  • Creating own plugins for sure have its benefits. It is easy to implement custom classes that can extend the core utility classes that Tailwind offers. But I’m skeptical that this would scale well for medium to large applications, since we now have to look into another file and probably this wouldn’t play well in a team environment.
