Hi:
I see a lot of cool REST apps and i'm trying to host something in the TIE using REST/Axios with VITE.
At the moment i will probably host the application in web applications in Intersytems.
For authorisation and getting the logged in user and password to any app, is there a standard people are doing?
I.e. for axios you might have this from the app
auth: {
username: apiUser,
password: apiPass
}gj :: configExplorer is a new VS Code extension integrating with Server Manager and leveraging Structurizr to produce configuration diagrams of your servers.
Here's a short introductory video.
By using the InterSystems IRIS Native API for Node.js it avoids the need for any support code to be installed on the servers. This technology choice also qualifies it for entry into the current Developer Community contest.
The initial release focuses on two aspects of server configuration:
Suggestions for what to add next are welcome, as is general feedback.
I have a class that extends %CSP.REST which made I deployed using $system.OBJ.MakeClassDeployed. After upgrading IRIS, the web app which uses that class no longer works with an ObjectScript error.
In the past, I fixed that problem by adding a dummy new line or a comment then recompiled that class. For this deployed class, I can't add a new line and recompile the class (the code shows up as locked in Studio). Simply running $system.OBJ.compile() is not fixing the web app issue.
Is there a way to edit a deployed class then recompile it?
Hey Community,
Enjoy the new video on InterSystems Developers YouTube:
Hello Community,
When I compile the Sample.User class for the first time, and include an ObjectGenerator method intended to run certain logic during each compilation, it throws a <CLASS DOES NOT EXIST> error. However, recompiling the same class works as expected.
I understand this happens because the class hasn’t been fully compiled yet during the first pass. To overcome this issue, are there any specific callback methods available that can safely be used after the class is fully compiled?
Here’s a quick checklist — but you can, of course, share anything else about your summer in the comments. Photos are more than welcome 📸
Hey Community,
It's time for the new batch of #KeyQuestions from the previous month.
Hi,
I have the following transform working but i also want to add another string of text for it to look for but i'm unsure of how to write this in. The two bits of text are "NOT DECTECTED" and "Negative"
To better understand Streams in IRIS I'll start with a short
In the beginning (before IRIS), there was just basic access to external devices.
The 4 commands OPEN, CLOSE, READ, WRITE still work and are documented
by Introduction to I/O in detail.
Especially for files, this is a direct access to your actual file system.
You have to take care of any status or other signal in your code.
Also, any code conversion or similar is up to you.
I need to ingest streaming data over WebSockets. How can I create a custom inbound adapter for IRIS productions that supports many concurrent socket connections?
We want to use IRIS as a backend for a lightweight blockchain or DLT. Can we model blocks using deterministic globals and implement consensus (PBFT, Raft) externally while using IRIS as the ledger?
We’re ingesting high-volume HL7 messages and converting them to FHIR in near-real-time. How do we design a streaming ETL pipeline using interoperability (productions) that scales horizontally?
Hi all,
It's me again 😁. In the pervious article Writing a REST api service for exporting the generated FHIR bundle in JSON, we actually generated a resource DocumentReference, with the content data encoded in Base64
Question!! Is it possible to write a REST service for decoding it? Because I am very curious what is the message data talking about🤔🤔🤔
OK, Let's start!
1. Create a new utility class datagen.utli.decodefhirjson.cls for decoding the data inside the DocumentReference
Class datagen.utli.decodefhirjson Extends%RegisteredObject

}I am trying to add Plotly Bar graph in a div to a CSPpage. I am working in IRIS 2022.1. I created persistent class.
I copied relevant code into github repo:
oliverwilms/iris-python-plotly
iris-python-plotly/csp/otwPlotly.csp at master · oliverwilms/iris-python-plotly
Set tPlotlyDiv = ##class(dc.python.test).PlotlyDiv(trnYear,trnMonth)
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.
@PerfmonReportIn 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.
I have a custom defined priority field that is being stored as a number type
<record name="LocalClinicalMeSHTerms" type="serial">
<field name="LocalClinicalExpertiseCodedValue" type="{CODETYPE}" codeFamily="HSPD" codeTable="LocalClinicalExpertise" codeScheme="{MASTER}"/>
<field name="LocalCliniclDisplayOrder" type="number"/>
</record>However, within the overviewIndividual.cls form
The built-in %JSONExport() fails with circular references in deeply nested objects. How can I write a custom serializer that supports circular detection and reference tracking?
Given a JSON schema at runtime, I want to programmatically create persistent classes with corresponding properties and indices. Is there a way to dynamically compile and load such classes?
Some languages have the concept of a garbage collector for automatic memory management. I'd like to know if something like this exists in InterSystems Caché in the context of routines, %CSP.REST, or %CSP.Page.
The question arises from the %Close() method of the %RegisteredObject class. This indicates that I need to manually clear the object from memory if it's no longer in use, or in the web context, if the request has completed. Is this correct? Or am I completely wrong?
Thank you!
I need to build an integration solution that reads messages from a Kafka topic. The topic has 3 partitions and contains several million messages.
For certain reasons, I can only use the standard EnsLib.Kafka.Service class and cannot use either KafkaClient or Python.
To measure performance and collect statistics I created a simple key + timestamp table with no indexes (so it is unlikely to be a bottleneck). Next, I started an instance of EnsLib.Kafka.Service. In the OnProcessInput method, I receive a message, extract the key from it, get the current time, and write the row to the table.

This anthropic article made me think of several InterSystems presentations and articles on the topic of data quality for AI applications. InterSystems is right that data quality is crucial for AI, but I imagined there would be room for small errors, but this study suggests otherwise. That small errors can lead to big hallucinations. What do you think of this? And how can InterSystems technology help?
The ObjectScript language has incredible JSON support through classes like %DynamicObject and %JSON.Adaptor. This support is due to the JSON format's immense popularity over the previous dominance of XML. JSON brought less verbosity to data representation and increased readability for humans who needed to interpret JSON content. To further reduce verbosity and increase readability, the YAML format was created. The very easy-to-read YAML format quickly became the most popular format for representing configurations and parameterizations, due to its readability and minimal verbosity. While XML is
I want to build an event store using raw globals and replay events for rebuilding state. Can I hook into IRIS journaling or write my own event log and replay engine?
We’re encountering occasional deadlocks when accessing persistent objects. How can I trace lock acquisition and identify cyclic dependencies in real time?
Can the IRIS SQL engine be extended with custom optimization rules (e.g., prioritizing certain indices or join orders)? If not, is there a supported way to influence cost models?
For geographically distributed nodes using async mirroring or ECP, how can I detect and resolve data conflicts manually (custom logic) while maintaining eventual consistency?
