How to display a “Calculating” message while a heavy program is running in the background to prevent lag
I have this react web app i'm working on. In one of the components, I have a program loops through multiple years, gets all the days between them and displays them i.e is a very heavy computation.
But this slows down the page and makes it laggy. Is there a way I can display a "calculating" message while the process runs in the background until it's done.
Here's what the code looks like:
class Component extends Component {
constructor(props) {
super(props);
this.state = {
days:
..
}
}
someComplexFunction(){
// Run the complex function and set the days state
..
}
componentDidMount() {
this.someComplexFunction();
}
render() {
return (
<div>
{/* MAP DAYS TO LIST ITEMS */}
..
</div>
);
}
}

I'd look at web workers for the computation. They run in a separate thread, so they won't block the UI thread. Combine this with the BusyWrapper below, and you have a winner.

create isBusy property which will be true before call and after response was received will become false and will manage calculating process
i used this https://material-ui.com/api/circular-progress/
example
import React, { PureComponent } from 'react';
import CircularProgress from '@material-ui/core/CircularProgress';
export default class BusyWrapper extends PureComponent {
render = _ => (
<section>
{this.props.isBusy &&
<div>
<CircularProgress
thickness={4}
/>
</div>
}
{this.props.children}
</section>
);
}
how use
<BusyWrapper
isBusy={this.state.isBusy}
>
<YourComponent>
</BusyWrapper>
