Been wanting to get my feet wet with Typescript to start working on custom widgets and learning some React. So I've followed the example here, which worked like a charm. The Typescript code includes the new kind of imports, which I imagine any Pythonista will prefer of the traditional require syntax in Javascript. import Map = require("esri/Map"); import MapView = require("esri/views/MapView");‍‍‍‍ But I really wanted to get it to work like this, which would look even more like Python: import Map from "esri/Map"; import MapView from "esri/views/MapView"; ‍‍ When I try that, the code still compiles successfully. But I get these intellisense warnings about  default exports...   Since I'm new to Typescript, I will have to read up on this import/export business. In the meantime, is this an innocuous warning? Based on this thread, I should be trying the following: import * as Map from "esri/Map"; import * as MapView from "esri/views/MapView";‍‍ But that blows up completely... app/main.ts:10:13 - error TS2351: Cannot use 'new' with an expression whose type lacks a call or construct signature. 10 const map = new Map({ ~~~~~~~~~ 11 basemap: "streets" ~~~~~~~~~~~~~~~~~~~~ 12 }); ~~ app/main.ts:7:1 7 import * as Map from "esri/Map"; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Type originates at this import. A namespace-style import cannot be called or constructed, and will cause a failure at runtime. Consider using a default import or import require here instead. ‍‍‍‍‍‍‍‍‍‍‍‍‍   This source suggests this setting in tsconfig.json "allowSyntheticDefaultImports": true When I try that, Dev Tools scream at me: Another tweak I tried came from here and looked like this: "maintainModuleNames" : true. But that didn't compile so well... tsconfig.json:13:7 - error TS5023: Unknown compiler option 'maintainModuleNames'.‍‍ Long story short, if anything here screams rookie mistake, please comment. Would love to get these beautiful imports to work.  ... View more

I am working on my local machine with JSAPI in VS Code, and I'm getting the following CORS related error thrown at me in Chrome Dev Tools: Access to XMLHttpRequest at 'https//... my environment ..../MapServer?f=json' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.‍‍‍‍‍‍‍‍ I've read enough about CORS to understand its purpose, and that according to ESRI, ... By default, ArcGIS Server allows cross-domain requests so Javascript clients can invoke the server's services from any domain.... (Restrict cross-domain requests to ArcGIS Server—ArcGIS Server Administration (Linux) | ArcGIS Enterprise) So I think no additional tweaks to the web server are warranted. I've been able to "work around" this by developing in a directory that's on the same Dev/Test box where my map services are running on. This works great. Additionally, I've reviewed 'Allowed Origins' in ArcGIS Server Administrator to make it meets my needs. Are there other adjustments I could make that would allow me to still do all my work locally and hit AGS map services without CORS issues? I get the sense from reading various threads online that a lot of folks new to working with JSAPI may be running into this. But I haven't found the ESRI documentation tremendously illuminating. ...

When I publish an ArcGIS Server map service (10.6) to my federated AGS, a Portal item gets automatically created with a cute little thumbnail that's generated from the current extent in ArcGIS Pro when publishing from Pro. Is there a way I can preserve that item thumbnail through future version of the same service? It's great to be able to select "Overwirte Web Layer" in Pro but it would be nice for your those browsing content if the thumbnail didn't change every time you re-publish. ... View more

So I've been busy publishing map services from an "old" standalone ArcGIS Server environment to Portal/Federated ArcGIS Server. Which means you create a map services and Portal creates a corresponding item. In the process, I've had to undo and clean up a few things. It's easy to wipe out map services with Python: from arcgis import gis mygis = gis.GIS(url, username='arcgis_python') gis_servers = gisprod.admin.servers.list() server1 = gis_servers[0] rest_folder = '<your_REST_endpoint_folder>' map_services = server1.services.list(rest_folder) for service in map_services: try: service.delete() except Exception as e: print(e.message)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Alternatively, of course, you could simply select the services in ArcCatalog and delete them, if you're so inclined. But the script is convenient, when you have a list of services to remove. But now what happens is that the service gets removed but the Portal item representing the services does not. Which results in a broken item. This happens even if the item is protected. The proper way to clean things up would be by removing the Portal item, which takes the map services with it. item = gisprod.content.get('7db0bc4128eb4d819794815e4654a358') item.delete(0‍‍)‍‍‍ However, if the map services is gone, is there a way to link that item back to the service? If I publish the map service again, this creates a new item with a new item Id. The old one doesn't show up more.  Also, for map services that show up as Portal items, what is the server id, when I interrogate dependencies: item.dependent_upon() {'total': 1, 'start': 1, 'num': 1, 'nextStart': -1, 'list': [{'dependencyType': 'serverId', 'id': 'FK7U7Hisd6qRFdPK'}]} ‍‍‍‍‍‍‍‍ What's the code 'FK7U7Hisd6qRFdPK' reference? ...

Trying to update data source for layers in ArcGIS Pro maps programmatically. So, I must be misunderstanding the syntax for doing that explained here. Because the following does not work: import arcpy aprx = arcpy.mp.ArcGISProject(r'path to my project file') #This gets me list of all the maps maplist = aprx.listMaps() #If I only want those belonging to MyGroup mygroup = aprx.listMaps('MyGroup')[0] #To get the layers in that group grouplayers = mygroup.listLayers() new_sdeConn = r'path to my SDE connection file' for lyr in grouplayers: old = lyr.connectionProperties #also tried lyr.connectionProperties['connection_info'] lyr.updateConnectionProperties(old, new_sdeConn)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ This doesn't throw an error. it just doesn't do update the data sources as desired. The ESRI example goes like: aprx.updateConnectionProperties(r'C:\Projects\YosemiteNP\Vector_Data\Yosemite.gdb', r'C:\Projects\YosemiteNP\DBConnections\Server.sde')‍‍‍‍‍‍ Does this maybe only work for the project as a whole? ...
