When creating a loading bar or progress bar with React, the basic steps are as follows: 1. Create the container to hold the progress bar.
<div class="progress-bar-container"></div>
2. Create a child component that will display the progress bar.
const ProgressBar = () => {
return (
<div>
<div class="progress-bar"></div>
</div>
);
}
3. Set a state value to control the width of the progress bar.
class ProgressBarContainer extends React.Component {
constructor(props) {
super(props);
this.state = {
width: 0
};
}
}
4. Increment the width value in the state with a timer. The timer can be set to a specific interval, or it can be based on an external event.
componentDidMount() {
this.timerID = setInterval(
() => this.incrementWidth(),
500
);
}
incrementWidth() {
this.setState({
width: this.state.width + 5
});
}
5. Pass the width value of the state to the ProgressBar component.
render() {
return (
<div class="progress-bar-container">
<ProgressBar width={this.state.width} />
</div>
);
}
6. Finally, use the width value to control the width of the progress bar.
const ProgressBar = (props) => {
return (
<div>
<div class="progress-bar" style={{ width: `${props.width}%` }}></div>
</div>
);
}
With the steps above, a basic React progress bar is created. There are various other ways to create a progress bar with React, such as using libraries or creating more complex components. However, the steps discussed above will create a simple and efficient progress bar.
