Add, update, and delete data in a hosted feature layer.
Prerequisites
An ArcGIS Location Platform, ArcGIS Online, or ArcGIS Enterprise account.
Steps
Create a private feature layer
For this tutorial, you will use the Santa Monica Parcels dataset to create a private hosted feature layer in your portal.
-
In your web browser, go to the Santa Monica Parcels item.
-
Click the Download button to download the zip file locally. Do not unzip this file.
-
Import the shapefile into ArcGIS.
-
In your web browser, go to ArcGIS.com and sign in with your ArcGIS Location Platform account.
-
In the top navigation bar, click Content.
-
Click New item. To upload the Santa Monica Parcels shapefile, you can either:
- Drag and drop the file.
- Or, click Your device and navigate to the file path.
-
Select Add Santa Monica Parcels.zip to publish the file as a hosted feature layer.
-
In Fields, leave all fields at their default settings and click Next.
-
In Location settings, leave the default settings and click Next.
-
Set the following information in the item details pane:
- Title:
Santa Monica Parcels
- Tags:
Santa Monica
Parcels
. - Summary:
Parcels in the Santa Monica Mountains.
- Title:
-
Click Next to create the new feature layer and feature service.
-
In the feature service item page, make sure the Share setting is set to Owner.
-
Scroll down to the URL section and copy the URL into a safe location. You will use this in a later step. The URL will look something like:
https
.://services3.arcgis.com/ G Vgb Jbqm8h XASV Yi/arcgis/rest/services/ Santa _Monica _Parcels/ Feature Server
-
-
In the feature layer item page, go to Settings.
-
Under Feature layer (hosted), check the Enable editing box.
-
Save your changes.
Get the starter app
Select a type of authentication below and follow the steps to create a new application.
Set up authentication
Create developer credentials in your portal for the type of authentication you selected.
Set developer credentials
Use the API key or OAuth developer credentials so your application can access location services.
Make the request
Copy and paste the code below, following the steps to make a request to the feature service.
-
Reference the
arcgis-rest-request
andarcgis-rest-feature-service
libraries either through CDN, ES Modules, or Node JS. -
Update the
<pre
element id to> result-add
. Add two more<pre
elements called> result-update
andresult-delete
. -
Paste the feature layer URL you copied earlier to the
feature
variable and appendLayer Url /0
at the end of the URL. -
Define the parameters needed for the request.
-
Call the feature service and handle the results.
