Build a Jokes Generator With Next JS and API

Last Updated : 01 Aug, 2024

Jokes generator application using Next Js is an application where we are using the external API to fetch the jokes. This application has features to copy the jokes and when the user clicks on "Get a Joke" new jokes will be generated.

Preview of final output: Let us have a look at how the final output will look like.

Prerequisites:

Introduction to Next.js
React Hooks
NPM or NPX

Approach to create Joke Generator:

In this Next.js application, the initial step involves defining a state through the utilization of useState. This allows for the management of three crucial elements: joke, error, and copySuccess.
The process of retrieving a random joke from an external API is handled by the getJoke function. It effectively resets any existing errors and clears the copy success message. In case there is a failure in making an API request, it will establish an error message accordingly.
On the other hand, the handleCopyClick function utilizes the clipboard API to enable copying of the joke text. Upon successful completion, it exhibits a "Copied!" message to confirm this action.
To enhance user experience and promote usability, this application offers a clean and responsive user interface incorporating both a "Get a Joke" button as well as a "Copy" button. For enhanced SEO optimization purposes, appropriate page title and description have been duly set.

Steps to create the Next JS App:

Step 1: Create a new Next.js project using the following command

npx create-next-app  jokes-generator-app

Step 2: Change to the project directory:

cd  jokes-generator-app

Project Structure:

The updated dependencies in package.json file will look like:

"dependencies": {
    "@fortawesome/fontawesome-svg-core": "^6.4.2",
    "@fortawesome/free-solid-svg-icons": "^6.4.2",
    "@fortawesome/react-fontawesome": "^0.2.0",
    "html2canvas": "^1.4.1",
    "next": "^13.0.6",
    "qrcode.react": "^3.1.0",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-icons": "^4.11.0"
}

Example: In this example, we will create the Jokes Generator App Using NextJs. Write the following code in App.js and App.css file

CSS

.container {     text-align: center;     background: rgba(255, 255, 255, 0.9);     width: 500px;     height: 350px;     font-family: 'Arial', sans-serif;     margin: 30px auto;     padding: 60px;     max-width: 800px;     background-color: white;     box-shadow: 0 2px 26px 0px rgba(0, 0, 0, 0.1);     border-radius: 15px;     border: 3px solid #ccc; }  .title {     font-size: 28px;     font-weight: bold;     color: #0984e3;     margin-bottom: 24px; }  .jokeText {     font-size: 24px;     font-weight: 400;     color: #333;     line-height: 1.4; }  .button, .copyButton {     background: #0984e3;     color: white;     border: none;     border-radius: 10px;     padding: 15px;     font-size: 16px;     font-weight: bold;     cursor: pointer;     transition: background-color 0.3s;     margin: 10px; }  .button:hover, .copyButton:hover {     background: #1453a5; }  .errorText {     color: #ff6b6b;     font-weight: bold;     margin-top: 16px;     font-size: 18px; }

JavaScript

import { useState } from 'react'; import Head from 'next/head'; import './App.css';  export default function Home() { 	const [joke, setJoke] = useState(''); 	const [error, setError] = useState(null); 	const [copySuccess, setCopySuccess] = useState(false);  	const getJoke = () => { 		// Reset any previous errors 		setError(null); 		// Reset the copy success message 		setCopySuccess(false);  		fetch('https://icanhazdadjoke.com/', { 			headers: { 				Accept: 'application/json', 			}, 		}) 			.then((response) => { 				if (!response.ok) { 					throw new Error('Failed to fetch joke'); 				} 				return response.json(); 			}) 			.then((data) => { 				setJoke(data.joke); 			}) 			.catch((error) => { 				setError('Failed to fetch joke. Please try again later.'); 				console.error(error); 			}); 	};  	const handleCopyClick = () => { 		navigator.clipboard.writeText(joke).then(() => { 			// Set copy success message 			setCopySuccess(true); 		}); 	};  	return ( 		<div className="container"> 			<Head> 				<title>Random Jokes Generator</title> 				<meta name="description" 					content="Random Jokes Generator" /> 			</Head>  			<div className="app"> 				<div className="card"> 					<h1 className="heading"> 						Random Jokes Generator 					</h1> 					<div className="jokeContainer"> 						{error ? ( 							<p className="errorText">{error}</p>):( 							<> 								<p className="jokeText">{joke}</p> 								<button className="copyButton" 									onClick={handleCopyClick}> 									{copySuccess ? 'Copied!' : 'Copy'} 								</button> 							</> 						)} 					</div> 					<button className='button' onClick={getJoke}> 						Get a Joke 					</button> 				</div> 			</div> 		</div> 	); }

Step 3: Run this command to start the application:

npm run dev

Step 4: To run the next.js application use the following command and then go to this URL:

 http://localhost:3000
