Hi All Is there a github repo where I can find the Jupyter notebook code demonstrated during DevSummit sessions ? I am after this one here: https://www.youtube.com/watch?v=UUotEDEVySs I tried the proceedings website, where I found only a link to the video and also the PowerPoint PDF https://proceedings.esri.com/library/userconf/devsummit20/index.html Thanks ...

Recently I came across ESRI web course Update Real-Time Data with Python, and it walks through a tutorial on how to built what is called "feed routine". The idea is basically is to read latest version of certain feature-set from a JSON file shared and accessed through a URL, and feed that into your system, which in this case is a hosted feature layer.  In this blog, I wanted to focus on the function "deployLogic" which takes places after reading the latest JSON data and converting it to ESRI file-geodatabase. This function demonstrate really important workflow on how to update the data of hosted feature layer, while keeping the hosted layer item id - as a Portal for ArcGIS or AGOL item. I didn't find similar workflow explained in the published documentation for ArcPy or API for Python, and I believe it can be accommodated to be used with more complex scenarios. I will try to summarize the function logic in the following bullets: Using 7zip sub-process, extract the hosted layer service definition file Browse to the extracted folder, reach the underlying source file gdb, and delete it Copy the fresh file-geodatabase that was created in previous step to the extracted service definition folder Using 7zip, compress the service definition folder into a new service definition file with '.sd' extension, not '.zip' Using "FeatureLayerCollectionManager" instance, update the hosted layer using the new service definition file The simplicity of this workflow is that it avoids republishing the service using ArcGIS Pro project, so you won't need to go through something like "getWebLayerSharingDraft" from a Map object, and worry about setting the needed flags "overwriteExistingService", etc.. I find this really easy shortcut, and it will get the job done. Update Real-Time Data with Python Update Real-Time Data with Python Update Real-Time Data with Python ... View more

This code sample can be seen as a simple "Hello World" app. It was built during a quick knowledge transfer session to demonstrate QML app structure, QML syntax, and basic concepts around editing a feature service. The app has only one button, where the click handler triggers adding point feature. The added feature geometry is generated from a random margin around the map center.  ... View more

Cool new features released with ArcGIS JS APIs 4.17, my first take aways: View Constraints: now you can limit the user navigation to be around certain geometry, help the user to focus on specific area Layer Visibility Animation: the APIs now supports fading effect while toggling layer visibility OGC Support: this is emphasized with 2 new features WCSLayer: new layer allows rendering raster data from OGC Web Coverage Service WMSLayer time enabled: now you can configured widgets like Time Slider with time-enabled WMS layers Widgets updates, now Bookmarks widgets saves the bookmark thumbnail, the user will have to set thumbnail URL  More details can be found in this ESRI blog: What’s New in ArcGIS API for JavaScript (October 2020)  New Code Samples for 4.17 Sample Code | ArcGIS API for JavaScript 4.17  ...
