React - create simple animated progress bar
3 points
Hello! 👋 😊
Today I want to show you a simple animated progress bar that I recently made in React.
Final effect of this post:
Below I present you my solution for a simple progress bar with some styling 📊🎨.
In this solution I use:
useStatehook to store the progress bar's state,- content
widthmeasured in percents according to the container - that trick lets us display progress from 0% to 100% in an easy way, - some example buttons that trigger
setProgress()method to demonstrate how progress bar works - animation between switching has a nice effect.
Practical example:
xxxxxxxxxx1
// import React from 'react';2
// import ReactDOM from 'react-dom';3

const containerStyle = {5
border: '1px solid silver',6
background: '#ededed'7
};8

const contentStyle = {10
background: '#00cc00',11
height: '24px',12
textAlign: 'center',13
lineHeight: '24px',14
fontFamily: 'sans-serif',15
transition: '0.3s'16
};17
18
const ProgressBar = ({progress}) => {19
const state = `${progress}%`;20
return (21
<div style={containerStyle}>22
<div style={{contentStyle, width: state}}>23
{progress > 5 ? state : ''}24
</div>25
</div>26
);27
};28
29
const App = () => {30
const [progress, setProgress] = React.useState(25);31
return (32
<div>33
<ProgressBar progress={progress} />34
<br />35
<div>36
<button onClick={() => setProgress(0)}>0%</button>37
<button onClick={() => setProgress(5)}>5%</button>38
<button onClick={() => setProgress(15)}>15%</button>39
<button onClick={() => setProgress(50)}>50%</button>40
<button onClick={() => setProgress(75)}>75%</button>41
<button onClick={() => setProgress(100)}>100%</button>42
</div>43
</div>44
);45
};46

const root = document.querySelector('#root');48
ReactDOM.render(<App />, root);
