points
In this short article we would like to show how to create animated progress bar in React.
Quick solution:
// ONLINE-RUNNER:browser;
// import React from 'react';
// import ReactDOM from 'react-dom';
const containerStyle = {
border: '1px solid silver',
background: '#ededed'
};
const contentStyle = {
background: '#00cc00',
height: '24px',
textAlign: 'center',
lineHeight: '24px',
fontFamily: 'sans-serif',
transition: '0.3s'
};
const ProgressBar = ({progress}) => {
const state = `${progress}%`;
return (
<div style={containerStyle}>
<div style={{...contentStyle, width: state}}>
{progress > 5 ? state : ''}
</div>
</div>
);
};
const App = () => {
const [progress, setProgress] = React.useState(25);
return (
<div>
<ProgressBar progress={progress} />
<br />
<div>
<button onClick={() => setProgress(0)}>0%</button>
<button onClick={() => setProgress(5)}>5%</button>
<button onClick={() => setProgress(15)}>15%</button>
<button onClick={() => setProgress(50)}>50%</button>
<button onClick={() => setProgress(75)}>75%</button>
<button onClick={() => setProgress(100)}>100%</button>
</div>
</div>
);
};
const root = document.querySelector('#root');
ReactDOM.render(<App />, root);
