Thanks for the detailed feedback! I think you probably used Functions when it was much newer, and I think we’ve actually addressed all of your issues.
- You can create a Function App via ARM/CLI/etc., you can write functions without ever touching the portal. See https://docs.microsoft.com/en-us/azure/azure-functions/funct.... You can also now use Visual Studio to author C# functions: https://docs.microsoft.com/en-us/azure/azure-functions/funct...
- It’s true that Functions is built on App Service, but I see that as an advantage. You get all the great features of Continuous Integration, custom domains, automated deployment, etc.
- Indeed, the portal does not do well when auth is enabled and all routes are protected. The problem is that the portal calls admin APIs that are also protected, so it fails. We now have better error messages for this, and we’re tracking this bug: https://github.com/Azure/azure-functions-ux/issues/499
- The Graph API issue is probably not specific to Functions, but it is a bit easier with the Authentication/Authorization feature. Can you provide more detail?
- You can install npm packages at the "root" of your Function and not reinstall them for each Function, just like a normal Node.js app - it walks the directories.
- Our documentation is much better now, and we even have documentation for all bindings in the portal. We also have much better conceptual docs on bindings, see https://docs.microsoft.com/en-us/azure/azure-functions/funct.... We’d welcome any specific feedback on docs that are missing.
- CI should be faster now, it usually takes about 2-3 minutes for commits to show up. It’s fast enough that I’ve demo’d it.
- You can now run locally and debug using the Azure Functions Core Tools (npm i -g azure-functions-core-tools; func init; func host start). See docs: https://docs.microsoft.com/en-us/azure/azure-functions/funct.... This is something that our users always praise us for. We support C# debugging with Visual Studio and JavaScript debugging with VSCode.
- Logs definitely weren't great. Initially, they always went to table storage, but the ones you see streaming in the portal get written to disk to enable the realtime portal stream - they are only written to disk when you're in the portal, so they are "sometimes" there. The good news is that we've tightly integrated Application Insights, which means logs are easy to find. It's easy to alert on failed functions. You can see perf and metric data all in one place without log parsing. For a demo, go to the 6 minute mark of this video: https://www.youtube.com/watch?v=TgB-fs1hwlw&t=6m
