tailwind npm (How It Works For Developers)

Tailwind CSS is a popular utility-first CSS framework that enables quickly to design HTML pages. It is highly customizable and works seamlessly with React, a powerful JavaScript library for building user interfaces. In this article, we'll guide you through the process of integrating Tailwind CSS into a React project using npm. Also, we will look into IronPDF PDF generation library to generate PDF from Website Urls.

What is Tailwind CSS?

Tailwind CSS is a utility-first CSS framework that allows you to create applications more efficiently. With Tailwind, you can control layout, color, spacing, typography, shadows, and more using utility classes directly in your HTML. The best part? You won’t need to write custom CSS! 🚀

If you’re tired of wrestling with traditional semantic class names, give Tailwind CSS a try—you might wonder how you ever worked with CSS any other way! 😊. Below are the steps to integrate Tailwind CSS into React application

Step 1: Create a React Project

Create React App using following command. This tool sets up a new React project with a sensible default configuration.

npx create-react-app my-tailwind-react-app
cd my-tailwind-react-app

npx create-react-app my-tailwind-react-app
cd my-tailwind-react-app

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npx create-react-app my-tailwind-react-app cd my-tailwind-react-app

Step 2: Install Tailwind CSS

Install Tailwind CSS and its dependencies using npm. Open your terminal and run the following command:

npm install -D tailwindcss postcss autoprefixer

npm install -D tailwindcss postcss autoprefixer

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npm install -D tailwindcss postcss autoprefixer

Step 3: Initialize Tailwind CSS

Next, you need to initialize Tailwind CSS to create the default configuration files. Run the following command:

npx tailwindcss init -p

npx tailwindcss init -p

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npx tailwindcss init -p

This will create two new files in your project: tailwind.config.js and postcss.config.js.

Step 4: Configure Tailwind CSS

Open the tailwind.config.js config file and set the purge option to remove unused CSS in production. This helps keep your final CSS bundle small. You can also define dark mode class name and also path to custom module here.

module.exports = {
  purge: ['./src/**/*.{js,jsx,ts,tsx}', './public/index.html'],
  darkMode: false, // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
}

module.exports = {
  purge: ['./src/**/*.{js,jsx,ts,tsx}', './public/index.html'],
  darkMode: false, // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
}

[module].exports = { purge: ( './src*.{js,jsx,ts,tsx}', './public/index.html'], darkMode: False, theme: { extend: {}}, variants: { extend: {}}, plugins: []}

Step 5: Create a Tailwind CSS File

Create a new file named src/tailwind.css and add the following content to it:

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

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

Dim MyBase As tailwind
Dim components As tailwind
Dim utilities As tailwind

Step 6: Import Tailwind CSS in Your React Project

Open the src/index.js file and import the Tailwind CSS file you just created:

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import './tailwind.css';
ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import './tailwind.css';
ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'import React from 'react'; import ReactDOM from 'react-dom'; import './index.css'; import App from './App'; import './tailwind.css'; ReactDOM.render(<React.StrictMode> <App /> </React.StrictMode>, document.getElementById('root'));

Step 7: Start Using Tailwind CSS

Now you can start using Tailwind CSS classes in your React components code. Open the src/App.js file and modify it as follows:

import React from 'react';
function App() {
  return (
    <div className="text-center min-h-screen flex items-center justify-center"> ## div class
      <header className="bg-blue-500 text-white p-8 rounded">
        <h1 className="text-4xl font-bold">Welcome to Tailwind CSS in React</h1>
        <p className="mt-4">This is a sample application using Tailwind CSS with React.</p>
      </header>
    </div>
  );
}
export default App;

import React from 'react';
function App() {
  return (
    <div className="text-center min-h-screen flex items-center justify-center"> ## div class
      <header className="bg-blue-500 text-white p-8 rounded">
        <h1 className="text-4xl font-bold">Welcome to Tailwind CSS in React</h1>
        <p className="mt-4">This is a sample application using Tailwind CSS with React.</p>
      </header>
    </div>
  );
}
export default App;

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'import React from 'react'; @function App() { Return(<div className="text-center min-h-screen flex items-center justify-center"> ## div class <header className="bg-blue-500 text-white p-8 rounded"> <h1 className="text-4xl font-bold"> Welcome @to Tailwind CSS in React</h1> <p className="mt-4"> This is a sample application using Tailwind CSS @with React.</p> </header> </div>); } export default App;

Step 8: Run Your React Project

Finally, start your development server to see Tailwind CSS in action:

npm start

npm start

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npm start

Your application should now be running with Tailwind CSS integrated. You can begin using Tailwind's utility classes to style your React components easily.

The above statements will create a 'tailwind.config.js' file as below:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./app/**/*.{js,ts,jsx,tsx,mdx}",
    "./pages/**/*.{js,ts,jsx,tsx,mdx}",
    "./components/**/*.{js,ts,jsx,tsx,mdx}",
    // Or if using `src` directory:
    "./src/**/*.{js,ts,jsx,tsx,mdx}",

    "./components/**/*.{js,ts,jsx,tsx,mdx}",
    // Or if using `src` directory:
    "./src/**/*.{js,ts,jsx,tsx,mdx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

''' @type {import('tailwindcss').Config} 
[module].exports = { content: ("./app/**/*.{js,ts,jsx,tsx,mdx}", "./pages/**/*.{js,ts,jsx,tsx,mdx}", "./components/**/*.{js,ts,jsx,tsx,mdx}", "./src/**/*.{js,ts,jsx,tsx,mdx}",), theme: { extend: {}}, plugins: ()}

Add below code to global.css file

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

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

Dim MyBase As tailwind
Dim components As tailwind
Dim utilities As tailwind

Open or create _app.js file and include the global.css file as below

// These styles apply to every route in the application
import '@/styles/globals.css'
export default function App({ Component, pageProps }) {
  return <Component {...pageProps} />
}

// These styles apply to every route in the application

Create a PDF

Now, let’s create a simple example of generating a PDF using IronPDF. In your Next.js component (e.g., pages/index.tsx), add the following code:

PDF Generation API: First step is to create a backend API to generate the PDF document. Since IronPDF only runs server side we need to create an API to call when a user wants to generate PDF. Create a file in path pages/api/pdf.js and add below contents.

IronPDF requires a license key, you can get it from the license page and place it in the below code.

// pages/api/pdf.js
import {IronPdfGlobalConfig, PdfDocument} from "@ironsoftware/ironpdf";
// Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Your license key";
export default async function handler(req, res) {
    try {
        const url = req.query.url
        const pdf = await PdfDocument.fromUrl(url);
        const data = await pdf.saveAsBuffer();
        console.error('data PDF:', data);
        res.setHeader('Content-Type', 'application/pdf');
        res.setHeader('Content-Disposition', 'attachment; filename=awesomeIron.pdf');
        res.send(data);
    } catch (error) {
        console.error('Error generating PDF:', error);
        res.status(500).end();
    }
}

// pages/api/pdf.js
import {IronPdfGlobalConfig, PdfDocument} from "@ironsoftware/ironpdf";
// Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Your license key";
export default async function handler(req, res) {
    try {
        const url = req.query.url
        const pdf = await PdfDocument.fromUrl(url);
        const data = await pdf.saveAsBuffer();
        console.error('data PDF:', data);
        res.setHeader('Content-Type', 'application/pdf');
        res.setHeader('Content-Disposition', 'attachment; filename=awesomeIron.pdf');
        res.send(data);
    } catch (error) {
        console.error('Error generating PDF:', error);
        res.status(500).end();
    }
