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.

I’ve recently developed %ZQueue, a process-based queue

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.

Application to Other Domains:

This approach can be applied to other domains such as

Dear community, I have a confession to make.I have not gotten over Zen yet.Alas, all good things must come to an EOF, so I am currently learning about Angular.I am working on proving to myself that with the right back end and Angular components, I can deliver to myself and my team a very Zen-like experience in this environment.Since this is my first attempt, here is a fair warning: I will be providing some rather large code samples before discussing them.Please warm up your mouse and hand for extensive upcoming scrolling!

Hi developers!

This will be a very short article as in April 2025 with Lovable and other Prompt-to-UI tools it becomes possible to build the frontend with prompting. Even to the folks like me who is not familiar with modern UI techics at all.

Well, I know at least the words javascript, typescript and ReactJS, so in this very short article we will be building the ReactJS UI to InterSystems FHIR server with Lovable.ai.

Let's go!

Question PagerianDeveloper · Mar 17, 2025

Is there a way to use a property of the type %Persistent class in a %ZEN.Component.page class?
Example:

// Data classClass PersistentClass Extends %Persistent
{
    Property Value As%String;
}
// Page classClass ClassName Extends%ZEN.Component.page
{
  Property TestProperty As PersistentClass
}


The problem is that when using it the described in the example.
The property can be set in a Method like this:

Method DoStuff() As %Status  [ ZenMethod ]
{
    Set result = ##class(HBS.EnsUtil.CompanyFunctions).GetData(.aVariable) // aVariable is of type PersistentClass
    Set..TestProper
