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.

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.

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.

Show All Class Members

You can view all members of the current class, including inherited members, with the click of a button. Just click on the class icon in the top-right corner of the editor window and a filterable list of all members will appear. Clicking on one will reveal it in an editor tab.

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.

Bringing Server-Sent Events to ObjectScript: Enabling AI Streaming

Introduction — The Problem with AI Streaming in ObjectScript

Today, I would like to introduce a problem I encountered and the solution I found when integrating AI APIs into an ObjectScript application. My initial tests were successful, yet somewhat frustrating.

The HTTP call worked; the request was properly sent to my LLM APIs. But then, silence... a long wait. Eventually, the entire response arrived as a single block.

Technically, it worked, but the user experience was disappointing compared to a ChatGPT session.

Trouble configuring Basic Authentication for SOAP Web Service in IRIS

Hi everyone,

I’ve configured an integration scenario in InterSystems IRIS with a Business Service exposed as a SOAP web service. Everything works correctly when the web application allows unauthenticated access.

However, when I switch the web application to require Basic Authentication, I’m unable to get it working properly. I have configured a resource and assigned it to both the web application and the user I’m using for the request, but I consistently get login failures (visible in the audit log).

Optimizing SQL LIKE Security, Performance and Best Practices

In my previous article, Using LIKE with Variables and Patterns in SQL, we explored how the LIKE predicate behaves in different scenarios, from Embedded SQL to Dynamic SQL, and what happens to performance when wildcards and variables come into play. That piece was about getting comfortable writing a working LIKE query. But writing SQL that works is only the starting point. To build applications that are reliable, scalable, and secure, you need to understand the best practices that underpin all SQL, including queries that use LIKE.

This article takes the next step. We’ll look at a few key points to help strengthen your SQL code, avoid common pitfalls, and make sure your SELECT statements run not just correctly, but also efficiently and safely. I'll use SELECT statements with LIKE predicate as an example along the way, showing how these broader principles directly affect your queries and their results.

*This is what Gemini came up with for this article, kinda cute.

Web Gateway access with Kerberos

Hello,

Looking for some additional help, maybe someone who has experience with this before, in setting up and configuring the Web Gateway with Kerberos.

Have read through the documentation (at the link below) and it's a good start but seems there are some details missing, or I'm not clear on. 

Questions: 

  • Is there a external enterprise Kerberos server required, or is this set up contained within the local server?
  • Is there a step-by-step instructions on what to do and configure to successfully complete this?
  • Are there there config changes necessary for Apache?
