Frontend world where is CSP is supposed to be part of, is growing very fast, and the best results you’ll achieve if you choose any way offered by the frontend community. And this is always depends your needs. Mostly known Angular, React and Vue.js.  The good things of using such popular frameworks, will be a lots developers for you, and that they are driven by the community and grows so fast. You still can use IRIS, as a backend, with REST for instance. Frontend developers may even don’t know what’s drive the backend, and how to deal with IRIS.

In addition to the demo described in the article, there is a simple flow for demonstration work with SQL.

And another demo, is mostly just for fun, to see how it's possible to create even some UI there.

With quite a complex flow like this

It was possible to create an interface like this

It allows, to create a new table in IRIS, and add some fields. For sure, too far from production use, but as a proof-of-concept.

All those demos are available in the repo.

At the moment we have only TextMate-based grammar in public, which is used in VSCode and on GitHub. I see no way of conversions from TextMate to Rouge. So, the only way would be to implement it from scratch. Not so easy, but still possible. 

I can do it, I have some experience in such tasks, but don't have so much spare time at the moment. Would be interested in investing in the project?

Well, there are few ways to do it. Look at the description to methods

Class Abstract.Test [ Abstract ]
{

/// Will return status with error, if the method not implemented
ClassMethod DoAction(pActionName) As %Status
{
  Quit $$$ERROR($$$GeneralError, "DoAction not implemented by " _ ..%ClassName(1))
}

/// Will throw an exception when method called, while not implemented 
ClassMethod DoCall(pActionName)
{
  Throw ##class(%Exception.General).%New("DoCall not implemented by " _ ..%ClassName(1))
}

/// Will not allow to compile descendants without implementing the method
ClassMethod AnotherAction(pActionName) As %Status [ CodeMode = objectgenerator ]
{
  If ('%class.Abstract) {
    Quit $$$ERROR($$$GeneralError, %method.Name _ " not implemented by " _ %classname)
  }
  Quit $$$OK
}

ClassMethod TestCall()
{
  Try {
    Set tSC = ..DoAction()
    If $$$ISERR(tSC) {
      Do $System.OBJ.DisplayError(tSC)
    }
    Do ..DoCall()
  }
  Catch ex {
    Write !,"Caught exception of type: ",ex.%ClassName(1)
    Write !,"Message: ",ex.DisplayString()
  }
}

}

AWS offers EC2, and it will be just virtual machines. And it will be possible to migrate any of your instances quite easy, if you would choose the same environment. If you have windows on your server, you can have Windows there as well. It's the easiest way. You would need to install the same version of the InterSystems platform you use, and repeat the configuration, copy necessary information and that's it. But for sure, could be some other options.

But AWS also suppose support for containers, this could be more difficult. And the best would be if you would use IRIS. I can help with this migration if you wish.

Yes, it’s not possible to edit BPL and some other resources which has their own UI editor with VSCode, yet. But, most of those kinds are classes in the end, and can be stored in source control system as classes, and you can edit them as classes, with no helpful UI, yes. There are a few limitations on implementing the current web editor to VSCode, mostly by security reasons, and I hope we’ll find a way how to solve it.

1) This is how ethernet works, if your ethernet cable have not connected, no connection and no IP address there. Sharing network over USB, as I know works fine on macOS, but not sure how to configure it for Windows. With macOS, it's possible to connect RaspberryPI with MacBook with USB-c to USB-C cable, and it will power it and gives access to the network.

2) Upgrading Docker-based applications, it the topic right for Docker. It's not so easy to explain how to upgrade Container. Containers are stateless, and the process is just to stop the existing container and start a new one from the updated image.

You don't have to extract archives supposed to be used by Docker. They have to be used as-is with command

docker load -i iris_community_arm64-2021.1.0.215.0-docker.tar.gz

and this will load the image to docker, and then it can be used there

Yes, InterSystems, offers distributions of IRIS, which can be installed without Docker. And for sure, you can run as many instances of IRIS as you want, as soon as you have enough resources for it.
