Great news for developers who have just started working with InterSystems IRIS! We have hands‑on interactive tutorials available via the Instruqt platform! These are perfect for getting up to speed quickly, playing in real environments, and building confidence with IRIS‑based development.
Here is the list of available tutorials:
Full Stack Tutorial - Experience how IRIS supports full-stack system architecture.
I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors.
How does a Payment Machine actually work?
It's simple, start by initiating/creating a transaction, then retrieve its payment status.
Here, initiate/create refers to POST methodand Retrieve refers to GET.
When exporting using the Export() method of the %Library.Global class, if the export format (fourth argument: OutputFormat) is set to 7, "Block format/Caché block format (%GOF)," mapped globals cannot be exported (only globals in the default global database of the namespace are exported). To export mapped globals in "Block format/Caché block format (%GOF)," specify the database directory to which you want to map them in the first parameter of %Library.Global.Export().
Technical Documentation — Quarkus IRIS Monitor System
1. Purpose and Scope
This module enables integration between Quarkus-based Java applications and InterSystems IRIS’s native performance monitoring capabilities.
It allows a developer to annotate methods with @PerfmonReport, which triggers IRIS’s ^PERFMON routines automatically around method execution, generating performance reports without manual intervention.

I'm developing an Ensemble process that sends user data from a Business Process to a Business Operation using EnsLib.SQL.OutboundAdapter. The operation is supposed to call a stored procedure on a SQL Server.
Sending emails is a common requirement in integration scenarios — whether for client reminders, automatic reports, or transaction confirmations. Static messages quickly become hard to maintain and personalize. This is where the templated_email module comes in, combining InterSystems IRIS Interoperability with the power of Jinja2 templates.
Why Jinja2 for Emails
Jinja2 is a popular templating engine from the Python ecosystem that enables fully dynamic content generation. It supports:
For those that use IRIS for Health, HealthShare, and or Health Connect...
As Health Applications are moving to the Cloud, how have you handled communication from the Application to your instances via HTTPS?
Trying to figure out the best path on designing the proper workflow to allow these messages to be allowed to be eventually sent to our EMR to post to the patient chart.
We are very wary of opening a connection from the internet to our instance of Health Connect.

I have a widget that uses "choose Data source" control option. Termlist for the control consist of the two data sources and i want to set one of them by default. For example: I have two data sources, one is grouped by month, the other by year. I need to set the one that is grouped by year by default
how to convert from json into sda container and then to fhir bundle resource. What are the out of the box DTL transformation class for this. Source would be my json that includes a few resources and targer should be a SDA container than will again be source to another transformation for which the target will be FHIR bundle. What I want to know is the target HS. 1for both SDA container and FHIR bundle. Thanks!
Hello community! I have a small challenge for you :)
One of customers is sending quite a lot of messages between interoperability components, which mix standard request content and streams representing serialized JSON objects. As these JSON streams can be quite long (but not too long, just couple hundreds of characters) they would appreciate if the JSON content of stream was displayed in a nice-to-read way, using syntax highlighting by message trace view.
I was wondering if anyone had a way to automate creating the Query String for a FHIR Request?
Using HS.FHIRServer.Interop.Request in my development I have to specify the following...
I was wondering.... if my source had variable number of fields if there was a way to automate the build for the QueryString when doing a Patient Search?
I'm pleased to announce the publication of gj :: dataLoader, a new VS Code extension that simplifies the task of loading data from local CSV files into SQL tables on your InterSystems IRIS servers.
Here's an introductory video:

I'm using from visual code. My routines are server-side files. If I try to search patterns in files (e.g find all routines containing the string "version=3") , the search runs but didn't find anything. If I do the same search from the management portal, it finds all routines including this pattern with a good performance.
If you are in the business of building a robust High Availability, Disaster Recovery or Stamping multiple environments rapidly and in a consistent manner Karmada may just be the engine powering your Cloning Facility.
This is the perfect opportunity for all InterSystems technology enthusiasts to share their knowledge and showcase their writing skills. No matter your experience level, everyone is welcome to participate. Articles can cover a wide range of topics, from technical implementation to your impressions and feedback on using InterSystems products or services. So let your creativity and expertise run wild!

🎁 Gifts for all: a special gift is prepared for each participant!
Overview I'm excited to announce the release of testcontainers-iris-node, a Node.js library that makes it easy to spin up temporary InterSystems IRIS containers for integration and E2E testing. This project is a natural addition to the existing family of Testcontainers adapters for IRIS, including testcontainers-iris-python and testcontainers-iris-java.
Why testcontainers-iris-node? As a Node.js developer working with InterSystems IRIS, I often faced challenges when setting up test environments that mimic production. testcontainers-iris-node solves this by leveraging the testcontainers-node framework to create isolated IRIS environments on-demand.
This is particularly valuable for:
Integration testing with IRIS databases
Testing data pipelines or microservices
Automating test environments in CI pipelines
Features
Launches IRIS in Docker containers using Testcontainers
Supports custom Docker images and configuration
Wait strategies to ensure IRIS is ready before tests begin
Date & Time: Monday, July 14 – 11 am EDT | 5 pm CEST
