Possible to create a Datasource programatically from a feature layer url?

aoestreicher — Fri, 25 Aug 2023 18:18:03 GMT

Hello, I am working on an app that needs to use a specific feature layer for each user, based on some back-end logic. we have feature layer urls stored in our database that contain the feature layer needed for each user. currently we can access it using a series of api calls made with FeatureLayer objects. however, we can not expose the data to experience builder as a whole, as I can't seem to find a way to make a data source from the url.

is it possible for me to programmatically create a data source based on this feature layer url? is this even the right approach?

Hi, I was curious if you were able to figure this out yet?

I am looking to implement a similar approach for one of my apps.

Thanks

@aoestreicher @jrhodes-gst Yes, you can use the data source manager.

import { DataSourceManager, Immutable, DataSourceTypes, /** FeatureLayerDataSourceConstructorOptions, DataSourceJson */ } from 'jimu-core' const featureLayerDs = await DataSourceManager.getInstance().createDataSource({ id: 'your_id', dataSourceJson: Immutable({ id: 'your_id', type: DataSourceTypes.FeatureLayer, url: 'https://your_domain/arcgis/rest/services/service_name/FeatureServer/0', layerId: '0', itemId: 'the_id', // optional portalUrl: 'https://org_name.arcgis.com', // optional ... // other properties in DataSourceJson }), layer: mapsSDKFeatureLayer, // optional, if you have one, https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-FeatureLayer.html, ... // other properties in FeatureLayerDataSourceConstructorOptions })
