Delete all features on website refresh (or end of session)

Good afternoon,

I am trying to achieve the following:

In an application built with experience builder, using the editor widget, delete all records when the website (application) is refreshed. I know that the whole purpose of the editor widget is to keep all data between sessions (the opposite of Draw widget which I do not want to use for different reasons). I have installed the Experience builder developer edition and trying to find the best option to go about it.

I am thinking of two options:

1. Automatize it somehow "behind the scenes" to delete all data when the session is refreshed.

2. Enable a new "delete all data" button that the user can click.

I would appreciate any help to point me in the right direction!

I will reply here to my own question because I found a solution: for simplicity I chose the second option, an unique button that will delete all data from the feature layer shown in the map widget. Here s the code of the widget.tsx:

/** @jsx jsx */ import { React, jsx, AllWidgetProps } from 'jimu-core'; import { JimuMapViewComponent, JimuMapView } from 'jimu-arcgis'; import { Button } from 'jimu-ui'; import FeatureLayer from 'esri/layers/FeatureLayer'; interface State { jimuMapView: JimuMapView; } export default class DeleteAllFeaturesWidget extends React.PureComponent<AllWidgetProps<{}>, State> { constructor(props) { super(props); this.state = { jimuMapView: null, }; } handleActiveViewChange = (jimuMapView: JimuMapView) => { this.setState({ jimuMapView }); } deleteAllFeatures = () => { const { jimuMapView } = this.state; if (jimuMapView && jimuMapView.view) { const layer = jimuMapView.view.map.layers.find((l) => l.type === 'feature') as FeatureLayer; if (layer) { layer.queryFeatures().then((results) => { const objectIds = results.features.map((feature) => feature.attributes[layer.objectIdField]); if (objectIds.length > 0) { layer.applyEdits({ deleteFeatures: objectIds.map((objectId) => ({ objectId })), }).then(() => { alert('All features deleted successfully.'); }).catch((error) => { console.error('Failed to delete features:', error); alert('Failed to delete features.'); }); } else { alert('No features found to delete.'); } }).catch((error) => { console.error('Failed to query features:', error); }); } else { alert('No feature layer found in the map.'); } } else { alert('MapView is not ready.'); } } render() { return ( <div className="widget-delete-all-features"> <JimuMapViewComponent useMapWidgetId="widget_1" onActiveViewChange={this.handleActiveViewChange} /> <Button type="primary" onClick={this.deleteAllFeatures}>Delete All</Button> </div> ); } }

Cheers!
