Small VS Code features that will boost your productivity

The official InterSystems VS Code extensions are packed with features that make developing with InterSystems products a breeze. Today I'd like to highlight some small but useful features that you may have missed.

Practical ObjectScript Coding: From JSON to Globals to SQL

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

How to merge existing accounts (update email) in the InterSystems Developer Ecosystem

Hi Community,

Sometimes you may need to merge multiple accounts or simply update the email address you use across the different portals in the InterSystems Developer Ecosystem. Since each portal works a little differently, here’s a guide to help you through the process.

Change your email

If you’d like to use a different email (for example, use a work email instead of a personal one, or vice versa), here’s how to update it across the portals:

1. Update your email in InterSystems SSO. To do this:

Beginner's Guide to %JSON and Dynamic Entities in IRIS

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

I created a table profile dashboard on Power BI, but I wonder if is possible to do it in Iris by creating a class.

No-Hallucinate MCP: Real-time Routine Context for ObjectScript

Motivation


Why do we need this?

  1. Lack of Compiled Context: AI tools only see source code; they don't know what the final compiled routine looks like.

  2. Macro Hallucination: Because AI doesn't see our #include files or system macros, it often makes them up, wasting time during debugging.

  3. The Documentation Gap: Deep logic optimization often requires understanding internal macros that aren't fully covered in public documentation.

  4. Manual Overhead: Currently, the only way to fix this is to manually use the IRIS VS Code extension to find the "truth" in the routine.

Code Golf! Alternating Vowels

Anyone up for a round of golf?

Are you fed up of making a machine write code for you? Do you miss thinking through problems yourself? Then you are in luck, this round, I propose adding the rule of no AI use. obviously its a game of honor with no prize, so I shan't be enforcing this, but you'll know... 

Challenge:

Create a function which takes a string as a parameter, and returns the length of thelongest sequence of alternating consonants and vowels. The sequence is broken by having two vowels or two consonants in a row.

Unable to connect to IRIS container through DBeaver via JDBC driver

So I am running IRIS 2023.3 via a Docker container on Windows 11 and when I go to System Administration > Connectivity > SQL Gateway Connections, I am able to connect to the iris container via jdbc. However, when I go to JBeaver and try connecting to IRIS via JDBC I am unable to do so. I know that this is a local laptop issue because when someone else runs it on t heir mac it works fine.

Modern and Easy-to-Use VSCode Plugin for InterSystems ObjectScript: Class Diagram Visualization with PlantUML

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:

Getting started with OAuth in your Web Apps

This article is intended as a beginner level article for people that want to learn how to use OAuth2 in their web applications natively.

There is an accompanying video/demo that may be helpful here: 

and you can reproduce this locally with the Open Exchange application attached.

OAuth2 as a native authentication type for web applications

OAuth (Open Authorization) 2.0 is a standard way to let one application call another application’s API without sharing a username and password.

Why It's Time for a TrakCare Techno-Functional Application Specialist Certification

Working in healthcare IT as a young developer, especially on InterSystems TrakCare, you quickly realize one thing: it’s not just about HL7 messages or backend integrations. A hugepart of making TrakCare work smoothly for hospitals comes down to how it’s configured, customized, and supported on the application side.

That’s where people like me come in—techno-functional developers who understand both the tech and how it impacts actual hospital workflows.

We’re Not Just Techies (or Functional Consultants)

Our role sits right in the middle.

Capturing and Sharing Patient-Level Measure Reports via FHIR Using Da Vinci Risk Adjustment with HealthShare

Overview

Organizations that need to capture, store, and share patient-level quality or risk adjustment measure results via FHIR can do so by extending HealthShare SDA and enabling transformation to the FHIR MeasureReport resource.

This article describes how to configure HealthShare to support the Da Vinci Risk Adjustment (RA) Implementation Guide by enabling storage and FHIR-based exchange of MeasureReport resources for individual patients or members.

Visualizing FHIR Patient Data with InterSystems IRIS for Health

Introduction

FHIR (Fast Healthcare Interoperability Resources) is the modern standard for storing and exchanging clinical data. But once your data is in a FHIR server, how do you actually explore it? FHIR data is stored as JSON — powerful, but not practical to read directly. I wanted a tool where you could click on a patient, see their conditions, medications, lab results, and more — in a clean, readable format. So I built the FHIR Patient Viewer.

How It Works

The app runs entirely in Docker and connects directly to an InterSystems IRIS for Health FHIR server.
