Glad to hear you were able to make it work. Debugging these issues can be really painful. Emulators help as you can easily work with the debugger, but emulators only tell you half the story...

I usually debugged and tested these scenarios on a real device, connected to the IDE on my laptop, which allows you to see exactly what is going on via the output window and the debugger of your IDE. 

I am not sure if I got the question right. If you already have a Zen or Zen Mojo application and would like to add a login page, I strongly recommend to develop the login page as a separate CSP/ZEN or Zen Mojo page. From my experience Zen Mojo is too heavy just to build a single simple login page (as it is designed for a complete SPA - single page application), so CSP or ZEN is recommended. If you are starting from scratch I usually recommend to pick a modern framework like Angular you feel comfortable with and communicate via JSON/REST to the backend. Responsiveness is usually achieved by a mix of picking UI libraries that are responsive by default (e.g. Bootstrap) and your own responsive CSS implementation. If you require a native application for mobile devices on iOS and Android (e.g. to interact with the camera) you have to be a bit more specific. But your options are either a native application (Swift or Java) or a hybrid (e.g. via Cordova or Ionic). The communication channel always is JSON/REST, so you have to start by designing your REST interface first, no matter what your web client looks like. At least for the majority of the use cases. Please let me know if you require additional information. HTH, Stefan

Indeed underscore characters are fully supported in the new JSON API (%DynamicObject and %DynamicArray). Are you sure this is the only change you made?

XEP for .NET does support both in-memory and TCP/IP connections. The client must be on the same machine for in-memory connections but can run remotely for TCP/IP connections. Long-term we will move away from in-process connections, but we haven't taken this step yet for XEP for .NET.

We consider support for .NET Core interesting and are currently evaluating support for it. But it is too premature to promise anything yet.



You are correct in your assumption, you have to work with streams to operate on arbitrarely large JSON. %ToJSON and %FromJSON work with streams. Here is an example how streams can work with %FromJSON to read a file:

        set fileStream = ##class(%Stream.FileCharacter).%New()
        set jsonObject = ##class(%DynamicObject).%FromJSON(fileStream)


We are in the process of updating our Hibernate dialect and plan to push the new dialect to the repository later this year. I got word from our developers that we are using the same strategy as Nicholas provided in his getDefaultMultiTableBulkIdStrategy implementation.

Thanks for sharing!

In case you are looking for an easy way to export SQL data to an Excel file as a developer:  I can recommend SQuirreL as SQL client, which offers Excel and HTML export capabilities.

I agree, Postman is a great tool.

If you want to document your REST interface, take a look at Swagger. You can generate an HTML documentation for your interface and test each call directly.
