Hi developers!

Observing the avalanche of AI-driven and vibe-coding developer tools that have been appearing lately almost every month with more and more exciting dev features, I was puzzled whether it is possible to leverage it with InterSystems IRIS. At least to build a frontend. And the answer - yes! At least with the approach I followed.

Here is my recipe to prompt the UI vs InterSystems IRIS Backend:

1. Have the REST API on the IRIS side, which reflects some Open API (swagger) spec.
2. Generate the UI with any vibe-coding tool (e.g., Lovable) and point the UI to the REST API endpoint.
3. Profit!

Here is the result of my own exercise - a 100% prompted UI vs IRIS REST API that allows to list, create, update delete entries of a persistent class (Open Exchange,frontend source, video):

What is the recipe in detail?

Hi developers. Just want to share with you a finding that might save you a few important minutes of your developer life with InterSystems IRIS.

But!

It should work; you deployed the REST API correctly, and everything is just in place.

What can go wrong?

Introduction

The standard %Net.HttpRequest library in InterSystems IRIS is powerful and comprehensive, but it can be verbose for simple operations. Writing an HTTP request often requires several lines of code to instantiate the class, configure the server, the port, HTTPS, add headers, and finally send the request.

When testing in the terminal, this configuration quickly becomes too heavy, and usually ends up with the creation of temporary methods...

FastHTTP was designed to address this need. This utility class provides a fluent and concise interface to perform HTTP calls in a single line, while automatically handling the underlying complexity (SSL/TLS, URL parsing, JSON encoding, headers, etc.).

Have you ever needed to change an IP or port before deploying an interface to production? Needed to remove items from an export? What about modifying the value(s) in a lookup table before deploying? Have you wanted to disable an interface before deploying? What about adding a comment, category, or alert setting to an interface before deploying to production?

If you’ve ever needed to make any changes to an interface or lookup table before deploying to production, then Export Editor is for you!

Hi Developers,

We are happy to announce the first InterSystems online programming contest of the year:

🏆 InterSystems Full Stack Contest 🏆

Duration: February 2 - March 1, 2026

Prize pool: $12,000

Hi Community,

Enjoy the new video on InterSystems Developers YouTube:

One objective of vectorization is to render unstructured text more machine-usable. Vector embeddings accomplish this by encoding the semantics of text as high-dimensional numeric vectors, which can be employed by advanced search algorithms (normally an approximate nearest neighbor algorithm like Hierarchical Navigable Small World). This not only improves our ability to interact with unstructured text programmatically but makes it searchable by context and by meaning beyond what is captured literally by keyword.

This is an excellent candidate for a developer community post (like Dev.to, Medium, or the InterSystems Community). It bridges the gap between high-level architecture and hands-on implementation.

Here is the summarized article format.

Building a Robust Asynchronous Queue Manager with InterSystems IRIS and Angular

As applications scale, handling heavy computational tasks synchronously becomes a bottleneck. Whether it's processing large data sets, sending high-volume emails, or managing API integrations, a decoupled architecture is essential.

Project Overview:

The Clinical Staff Master Data Management (CSMDM) system is a full-stack healthcare integration application built on InterSystems IRIS for Health. It centralizes and standardizes clinical staff metadata into a single authoritative repository, exposed through RESTful CRUD APIs and reusable backend methods.

The platform eliminates fragmented lookup tables and hardcoded mappings that commonly cause errors in HL7 and FHIR integration workflows, ensuring data consistency and interface reliability.

Hi everyone, 

This is the first time I'm dealing  with a request of modifying a variable value in a UDF OnSQLTrigger on InterSystems TrakCare.

I can't find any documentation to address this issue, but basically, my goal is to modify the value of one of the fields in a table when it is first inserted. 

This is basically what the code should do, namely, to change the content of the %d variable at a specific key.

Hi developers!

I'm testing vibecoding with ObjectScript and my silicon friend created a code-block that got me thinking "what's wrong"?

Here is the piece of code:

for i=0:1:(json.%Size()-1) {

set p = json.%Get(i)

if (p="value1")!(p="value2") {

quit 1
}

AI wanted to quit from a method with a return value. Good intention, but bad use of the command.

And ObjectScript compiler compiles this code with no error(?) (syntax linter in VSCode says it's a syntax, kudos @Brett Saviano ).

But in action, it produces <COMMAND>, of course.

Hi Developers!

Currently I have 2000+ lines in a class, and I think it's a lot already? What are the best practices? 

if 10K lines OK? How do you cope with it? Please share?

Greetings,

As a long time Cache developer is there a way to get a copy of the Cache Studio that supports IRIS 2024.3? I do not have a WRC account? I need Studio just to experiment, not to build commercial software.

Thank you,

Everardo

Hi, Community!

👩‍⚕️If you need to access clinical data at scale, the InterSystems Bulk FHIR Coordinator can help!

Using the InterSystems Bulk FHIR Coordinator to Extract Clinical Data

We use local containers  a lot for evaluation and development with Health Connect and other IRIS based applications.

When evaluating Podman Desktop on Windows as replacement for Docker Desktop, we are experiencing an issue with the durable %SYS:

The only way it works is when we use a named volume which then is located inside the WSL-Podman-Machine under /var/lib/containers/storage/volumes/.

When I build docker containers my build log usually looks like this:

Hello Team,

I am currently working with the CD Ruby machine, which is connected through DIGI. When I click on the “Test Link” option on the instrument, I can see the following behavior in Wireshark logs:

Ensemble sends an ACK (06) after receiving ENQ (05), followed by EOT (04) (somewhat like above photo). However, when another ENQ is received, Ensemble does not send an ACK in response. As a result, the instrument displays a failure message.

Also attaching the Ensemble settings:

I am using a TCP service with an inbound adapter configured for the ASTM protocol.

In the previous article, we examined how we can use the %CSP.Request and %CSP.Response classes to test a REST API without having the API fully set up and accessible across a network with an authentication mechanism. In this article, we will build on that foundation to perform some simple unit testing of one of our REST API methods.

The unit testing framework requires a couple of setup steps before we can use it. First, we have to ensure that the unit testing portion of the management portal is enabled so we can review the results of our tests.

We are attempting to "Repoint" old class data to new class data to save disk space and data redundancy across multiple tables. This works to a point.  In essence the two classes are sharing the same data / Index / stream globals.  But if an ID in the Old_Class is opened, a property is modified, and saved the property that is in the New_Class (but not in the Old_Class) is NULLed / blanked.

Simplified explanation of data and what’s occurring.

Intersystems IRIS Productions provide a powerful framework for connecting disparate systems across various protocols and message formats in a reliable, observable, and scalable manner. intersystems_pyprod, short for InterSystems Python Productions, is a Python library that enables developers to build these interoperability components entirely in Python. Designed for flexibility, it supports a hybrid approach: you can seamlessly mix new Python-based components with existing ObjectScript-based ones, leveraging your established IRIS infrastructure.

Welcome to the finale of our journey in building MAIS.

• In Part 1, we constructed the agnostic "Brain" using LiteLLM and IRIS.
• In Part 2, we designed the "Persona", mastering Dynamic Prompt Engineering and the ReAct theory.

Now, the stage is set. Our agents are ready, defined, and eager to work. However, they remain frozen in time. They require a mechanism to drive the conversation, execute their requested tools, and pass the baton to one another.

Today, we will assemble the Nervous System.

Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

s r = ##class(User.ADGroup).%New()
s json = {"code": "123", "text":"456", "oazisCode": ["1","2"]}
d r.%JSONImport(json)
w r.oazisCode.
