How to Set Up a Loading State for Embedded Insights

The components BaseChart, Execute, Kpi, Table, and Visualization imported from @gooddata/react-components contain the onLoadingChanged property.

The onLoadingChanged property is a function that returns either a { isLoading: true } object or a { isLoading: false } object.

To your local state, add a flag that indicates whether the GoodData component is currently loading or not based on what object is returned. Based on this flag, define what custom-styled loading element should be shown while the GoodData component is loading.

Example

This example uses data from the GoodSales demo workspace. For testing purposes, you can use this snippet as is.

import React, { PureComponent } from 'react';
import { Visualization } from '@gooddata/react-components';
 
export default class SampleVisualization extends PureComponent {
    constructor(props) {
        super(props);
 
        this.onLoadingChanged = this.onLoadingChanged.bind(this);
        this.state = {
            isLoading: true
        };
    }
 
    onLoadingChanged({ isLoading }) {
        this.setState({
            isLoading
        });
    }
 
    renderLoading() {
        if (this.state.isLoading) {
            return (
                <div>Loading</div>
            );
        }
 
        return null;
    }
 
    renderVisualization() {
        return (
            <Visualization
                identifier="aby3polcaFxy"
                projectId="la84vcyhrq8jwbu4wpipw66q2sqeb923"
                onLoadingChanged={this.onLoadingChanged}
            />
        );
    }
 
    render() {
        return (
            <div style={{ height: 400, width: 600 }}>
                {this.renderLoading()}
                {this.renderVisualization()}
            </div>
        );
    }
}
