Following 2 local Webinars we had focused on VS Code ["Intro" and "Beyond Basics"; in Hebrew], I prepared for the participants some related links of relevant resources which we sent as a follow-up. Sharing them here as well for the benefit of the Community.
You are all of course welcome to add more useful resources.

Hey Community!

We're happy to share a new video from our InterSystems Developers YouTube:

8. Conclusion and what’s next

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.

When using a EnsLib.RecordMap.Service.FileService business service, is there a way to tell which row number that is being read in? I want to read in a csv, but on the first record, trigger a truncate on the External SQL Table that it is being written to through JDBC.

Thanks

What is XML?

What is JWT?

JWT (JSON Web Token) is an open standard (RFC 7519) that offers a lightweight, compact, and self-contained method for securely transmitting information between two parties. It is commonly used in web applications for authentication, authorization, and information exchange.

A JWT is typically composed of three parts:

1. JOSE (JSON Object Signing and Encryption) Header
2. Payload
3. Signature

ObjectScript doesn't include any built-in method for appending one JSON dynamic array to another. Here's a code snippet I use that's equivalent to the JavaScript concat() method.

Call it with any number of arguments to concatenate them into a new array. If an argument is a dynamic array, its elements will be added. Otherwise the argument itself will be added.

For one of our customers I had to integrate with the AFAS imageconnector endpoint /imageconnector/{imageId}?format={format}.
This endpoint returns in a json message with the image as a base64-encoded string property, in addition to the mimetype for the image:

Introduction

My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.

I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database.

Motivation

I didn't know about ObjectScript until I started my new job. Objectscript isn't actually a young programming language. Compared to C++, Java and Python, the community isn't as active, but we're keen to make this place more vibrant, aren't we?

I've noticed that some of my colleagues are finding it tricky to get their heads around the class relationships in these huge projects. There aren't any easy-to-use modern class diagram tool for ObjectScript.

Related Work

I have tried relavant works:

Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.

Only method/routine executed as "do Method..." is included into $ESTACK.
How can I modify a method or routine that returns a value so it can be included in $ESTACK?
Example upon executing via Studio Debug ($ESTACK is converted to string with ">" delimiter):
Expected: stackstr = %Debugger.System.DebugStub > LogGenerate > Entry > DirChain > Attributes > LogNew > LogSize > LogFormat > LogWrite
Processes DirChain, LogNew, LogSize, LogFormat are executed as "If Method..."
