React - Wait for complex method to finish before rendering
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm trying to display a dashboard component, crunching a lot of data fetched from my redux store. This component takes a lot of time to render, mainly because of a single complex method.
Is it possible to render some kind of loader or placeholder while this method is processing ?
I tried doing so by using ComponentDidMount, but it seems like, because the method is part of my render() method, it will always be triggered first-hand.

Yes! Check out this tutorial.
Loader:
import React, {Component} from 'react';
const asyncComponent = (importComponent) => {
return class extends Component {
state = {
component: null
}
componentDidMount() {
importComponent()
.then(cmp => {
this.setState({component: cmp.default});
});
}
render() {
const C = this.state.component;
return C ? <C {...this.props}/> : null;
}
}
};
export default asyncComponent;
Usage:
import React from 'react';
import asyncComponent from '../../hoc/asyncComponent';
const AsyncButton = asyncComponent(() => {
return import('../Button');
});
const container = () => {
return (
<div>
<h1>Here goes an async loaded button component</h1>
<AsyncButton/>
</div>
);
};
