I just learned about a tool called Grit, which is a tool for rewriting code. Has anyone here ever used it in their own projects? Grit looks like it would be useful in my build process to covert standard JavaScript imports and dynamic imports into calls to the $arcgis.import function. I would like to avoid reinventing the wheel, so before I try to implement this on my own, I was wondering if anyone here had already used Grit in this manner. (Grit seems like the kind of thing @ReneRubalcava might have tried out, but I didn't find anything on his YouTube channel or blog.)

There is a discussion about this in a different thread with some alternative interfaces. My agency has an SOE that depends on these interfaces and opened a support case with Esri about it. They plan to reintroduce these interfaces in some future version at some undetermined point in time. ENH-000130183: "Add the ArcObjects Location library to the ArcGIS Enterprise SDK" Use Case One use case: the user has existing SOEs created for ArcMap. [It's actually the ArcGIS Server ArcObjects SDK, but they're referring to the fact that that these are map services that are published with ArcMap.] They would like to migrate to the Enterprise SDK to use them with Pro services. They use geometric networks and linear referencing to determine locations and relevant attribute information in the soe, so it will not be easy to migrate without this library. Specifically: IRouteLocator2, IRouteLocation, IRouteMeasurePointLocation, IRouteLocation, IRouteMeasureLineLocation, IEnumRouteIdentifyResult, and IRouteMeasurePointLocation. We are also investigating some non-Esri alternatives. NetTopologySuite - NetTopologySuite is .NET port of the Java library, JTS. We got this working but encountered an issue (not sure if its a bug or if we were somehow using it wrong) that prevented us from using it: if you specify a begin and end measure on a polyline, and those measures span two different lines within the polyline, the output segment should also be a polyline, but instead the gap between the lines is incorrectly connected. I do not know if JTS has the same issue. GDAL ogrlineref - The open-source GDAL is installed when ArcGIS software is installed. We haven't had time to do must investigating of this option. At the time we looked into ogrlineref, the Python implementation of GDAL didn't expose ogrlineref. PostGIS - PostgreSQL has built-in support for linear referencing via PostGIS. Migrating our LRS data from SQL Server to PostgreSQL / PostGIS would allow LRS functions to be carried out in database queries. We haven't tested this option at all, so we don't know if the LRS functions work the way we think they will. (I.e., it's possible we could encounter the same issue that we did with NetTopologySuite.)

@ReneRubalcava: I have created an improved type definition for $arcgis.import and put it on GitHub. It is Unlicensed, so anyone can use it and incorporate it into their own code without asking for permission. I used ChatGPT to help generate a script to dump a list of mappings, so developers using $arcgis.import no longer need to specify the type parameter. I haven't yet packaged it and put it in a repository (e.g., NPM), but I think users can directly add the GitHub repo as a package to their project. (I haven't tested this. If that doesn't work, they can just copy the d.ts file into their own project.) Edit I have since published it as an npm package: @wsdot/arcgis-core-helper I renamed the GitHub repo, so I have updated its link.

When I try to use $arcgis.import to load modules via CDN, TypeScript throws an error, saying there is no global variable named $argis. error TS2339: Property '$arcgis' does not exist on type 'Window & typeof globalThis'. How do I get TypeScript to recognize $arcgis? I've figured out that $arcgis is defined in "@arcgis/core-adapter". I can get Visual Studio Code to stop complaining if I add "@arcgis/core-adapter" to package.json, but tsc still throws the error. // This gets Visual Studio Code to stop complaining, but not tsc. const FeatureLayer = await window.$arcgis.import<typeof __esri.FeatureLayer>("@arcgis/core/layers/FeatureLayer.js");

Yeah, Esri should really include the typing information. I have a GitHub repo containing arcpy typestubs, but they are not complete. I used pyright to generate typestub files as a starting point, then have been cleaning them up gradually as I actually use the various classes, functions, etc..

Thanks, but what I was asking is if there was a simple "Reset to defaults" REST endpoint or button in Manager or something of that nature. (I already am aware of how to look up what the defaults were and change them.) On our production ArcGIS Server, I can't make these changes myself and have to instruct someone else on what I want them to do. I was hoping there was a simple "reset" command I could point them to that I was not seeing in the documentation.

On my agency's ArcGIS Server, when you go to an individual map service's page, some of the "View in..." links at the top of these pages don't work correctly. The URLs are all http rather than https, and the JavaScript API links are currently configured to point to the old 3.X version of the API which is no longer supported and thus when the user clicks on the link the page they're taken to doesn't work. I found the documentation about how to EDIT these settings, but I was wondering if there was a way to "reset to Esri recommended defaults" rather than editing individual settings one-by-one.

I encountered this recently and opened a support issue. They told me it's a known bug. (They've not yet given me an ETA on a patch or fix yet.) #BUG-000146430 This is a really serious issue, as it prevents you from publishing GP services or sharing in a GP package from tools in an atbx. You're not allowed to publish tools without metadata, and you can't add metadata to the tools. This is how I found out about the bug. Luckily the logic of the tools were in Python scripts, so recreating the toolbox portion in the legacy format wasn't too difficult. I'd hate to be the person that had to recreate all their model builder models because of this bug.

.NET 5 (the next major version of .NET Core) is scheduled to be released in 2020, and will supersede the .NET Framework. Targeting .NET Standard going forward would be a good idea so you will be ready by then.

After upgrading to ArcGIS Pro 2.0, I am no longer having this issue. Perhaps there was a bug in earlier versions, but I don't know for sure.

You're not assigning the URL to the esriConfig.portalUrl. You're currently creating an unrelated variable called portalUrl and assigning a value to it, while esriConfig.portalUrl remains unchanged.

Is there any way to call the arcpy.mp.CreateWebLayerSDDraft function outside of an active ArcGIS Pro session? I can't seem to find any way of programmatically logging in to ArcGIS Online through arcpy. """Publishes an ArcGIS Pro project's map to ArcGIS Online. """ import re from os.path import abspath, exists import arcpy from arcpy import AddMessage, AddError from arcpy.mp import ArcGISProject, CreateWebLayerSDDraft def main(project_path='traffic-map.aprx', service_name="Traveler_Info", folder_name="Traveler_Info"): """Publishes a project map to a service """ project_path = abspath(project_path) if not exists(project_path): raise FileNotFoundError("File not found: %s" % project_path) # Open the project AddMessage("Opening %s" % project_path) aprx = ArcGISProject(project_path) # Get the first map the_map = aprx.listMaps()[0] the_layers = the_map.listLayers() # Create the output path string by replacing the file extension. draft_path = re.sub(r"\.aprx$", ".sddraft", project_path) AddMessage("Creating %s from %s..." % (project_path, draft_path)) # Create the web layer SDDraft file. try: # TODO: Fails here with a RuntimeError that has no message if # ArcGIS Pro is not open and signed in to ArcGIS Online.

The ArcGIS JavaScript API only runs on the client-side (i.e., in the browser), so it shouldn't matter what technology you use on the server-side.

Have you tried using arcpy.da.UpdateCursor rather than the Calculate Field tool? That's how I would accomplish this task.

I happened to be looking at the Bower site today and noticed this message: ...psst! While Bower is maintained, we recommend yarn and webpack for new front-end projects! Also their latest blog entry (from last Oct.) is about using yarn instead of the Bower API.
