In this article, a Random Name GeĀnerator will be created using React.js. Building a Random Name Generator means creating a program or application that generates random names, typically for various purposes like usernames, fictional characters, or data testing. It usually involves combining or selecting names from predefined lists or patterns.
Prerequisites
- Introduction to React
- React Components
- ReactJS Hooks
- NPM or NPX
Steps to Create a React Application
Create a react application by using this command
npx create-react-app random-name-generator
After creating your project folder, i.e. random-name-generator, use the following command to navigate to it:
cd random-name-generator
Project Structure
The package.json file will look like:
{
"name": "random-name-generator",
"version": "0.0.0",
"private": true,
"dependencies": {
"react": "18.2.0",
"react-dom": "18.2.0"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
},
"devDependencies": {
"react-scripts": "latest"
}
}
Approach / Functionalities
The provideĀd React.js code showcases a Random NameĀ Generator, allowing users to dynamically geĀnerate and manipulate nameĀs.
- Dynamic Name Generation: It allows users to generate and manipulate names using the generateRandomName function, which selects random first and last names from predefined lists.
- Copying Generated Names: Users can easily copy the generated name to the clipboard using the copyToClipboard function.
- Modifying Names: Users have the option to modify either the first or last name using the changeFirstName and changeLastName functions.
- Real-time Updates: The app uses Reactās useState for state management, ensuring real-time updates of the generated name as users interact with the interface.
- User-Friendly Interface: The user interface provides a seamless experience for generating, copying, and modifying names, enhancing user interaction.
Example: Write the below code in App.js file and style.css in the src directory
Javascript
// App.js import React, { useState } from 'react'; import './style.css'; Ā Ā const App = () => { Ā Ā Ā Ā Ā Ā // Generated name, copied status, andĀ Ā Ā Ā Ā // lists of first and last names mustĀ Ā Ā Ā Ā // all be stored in state variables.
