Create a Password Generator App with React

Getting Started

Before we dive into creating a password generator app with React, let’s set up a new React application using create-react-app with npx. Make sure you have Node.js installed on your computer. Open a command prompt or terminal, navigate to the directory where you want to add your project, and type the following:

npx create-react-app my-password-generator

Components and Helpers

Our app will consist of several reusable components, including a slider, button, checkbox, and tooltip. We’ll also create a helper file to generate passwords with various combinations of characters.

Create a new folder called components inside the src directory, and add the following folders and files:

• container folder with Slider.js, Slider.css, CheckBox.js, CheckBox.css, and Tooltip.js files
• utils folder with a Helper.js file

Header and Display Components

Create a Header.js file inside the components folder and add the following code:

“`
import React from ‘eact’;

const Header = () => {
return

Password Generator

;
};

export default Header;
“`

Create a Display.js file inside the components folder and add the following code:

“`
import React, { useState, useRef } from ‘eact’;

const Display = () => {
const [password, setPassword] = useState(”);
const passwordRef = useRef(null);

// Add a function to display the password description
const setBackgroundColor = (password) => {
if (password.length < 5) return ‘ed’;
if (password.length < 10) return ‘yellow’;
return ‘green’;
};

return (

);
};

export default Display;
“`

Slider Component

Create a Slider.js file inside the container folder and add the following code:

“`
import React, { useState } from ‘eact’;

const Slider = ({ onChangeValue }) => {
const [rangeValue, setRangeValue] = useState(12);

const handleChange = (e) => {
setRangeValue(e.target.value);
onChangeValue(e.target.value);
};

return (

);
};

export default Slider;
“`

Checkbox Component

Create a CheckBox.js file inside the container folder and add the following code:

“`
import React from ‘eact’;

const CheckBox = ({ label, checked, onChange }) => {
return (

);
};

export default CheckBox;
“`

Tooltip Component

Create a Tooltip.js file inside the container folder and add the following code:

“`
import React from ‘eact’;

const Tooltip = ({ message, position, displayTooltip }) => {
return (

);
};

export default Tooltip;
“`

Helper Functions

Create a Helper.js file inside the utils folder and add the following code:

“`
const generatePassword = (length, uppercase, lowercase, symbols, numbers) => {
// Generate password logic here
};

const copyToClipBoard = (element) => {
element.select();
document.execCommand(‘copy’);
};

export { generatePassword, copyToClipBoard };
“`

Putting it all Together

Now that we have our components and helper functions set up, let’s put everything together. Create a Main.js file inside the components folder and add the following code:

“`
import React from ‘eact’;
import Header from ‘./Header’;
import Display from ‘./Display’;
import Slider from ‘./container/Slider’;
import CheckBox from ‘./container/CheckBox’;
import Tooltip from ‘./container/Tooltip’;

const Main = () => {
// Add state and methods here
return (

);
};

export default Main;
“`

Final Result

Our password generator app is now complete! You can run the app by typing npm start in your terminal, and you should see a password generator with a slider, checkboxes, and a tooltip. You can customize the app further by adding more features and styles.

Note: You can find the complete source code on GitHub.
