JavaScript, often abbreviated as JS, is a high-level, interpreted programming language. It is a language which is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm.
I am trying to use upload.csp as a template for choosing a CDV file to process. I am calling it from a zen page using this: <button caption="Import Client Consultation Extract" controlStyle="width:500px; height:100px; font-size:1.5em;"
The typeorm-iris project provides experimental support for integrating TypeORM with InterSystems IRIS, enabling developers to interact with IRIS using TypeORM’s well-known decorators and repository abstractions. This allows a more familiar development experience for JavaScript and TypeScript developers building Node.js applications with IRIS as the backend database.
While the project implements key integration points with TypeORM and supports basic entity operations, it’s not yet battle-tested or suitable for production environments.
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.
Working on wrapping an IRIS Cache ObjectScript method that runs for a few seconds. Trying to get UI updates to show BEFORE the method runs in an async/await function. But it seems to be running synchronously rather than asynchronously . So my question is does IRIS/ObjectScript CSP pages support futures with JavaScript or does it run all synchronously.
If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:
I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.
I would have to clear my cache files or browser history for it to reload and work.
For a long time I have wanted to learn the Django framework, but another more pressing project has always taken priority. Like many developers, I use python when it comes to machine learning, but when I first learned web programming PHP was still enjoying primacy, and so when it was time for me to pick up a new complicated framework for creating web applications to publish my machine learning work, I still turned to PHP.
Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data. This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client. This has had me scratching my head in so many ways.
I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.
Hello, Does the NodeJs package work when running a node js file on windows (nodejs for windows)? I've added the package by running npm install <package location folder>
I have the following index.js file, but when running from node (windows) I get the following error. Does the NodeJs package build the output files when the package is added or does it just assume linux as the underlying os?
My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.
I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database.
I have a CSP page I am developing with the intent of pulling files from an SFTP site and placing them in a folder on the local network.
I am having an issue where the CSP page is catching a JS error. The error in the browser is - A JavaScript exception was caught during execution of HyperEvent: SyntaxError: Unexpected identifier 'downloading'. (However, the unexpected identifier changes after refreshing page, or after removing the Write statement with the work 'downloading' in it.)
I think I have narrowed it down to a piece of the Javascript code -
I am working on a product that uses REGEX and matches it. The regex is tested both on the client-side (using the JavaScript REGEX engine) and both on the server-side.
But I couldn't find one word about the way intersystems parses the regex, It is quite elementary to state which which engine it works with.
from what I could gather from early implementations and such, the engine is based off PCRE, But I need to confirm this somehow, Can anyone give me a definitive answer, Is there any tool to test the regex other than writing it myself??
Managing databases and performing CRUD operations are fundamental tasks for developers building data-driven applications. While many database management systems (DBMS) exist, they can be complex and cumbersome to interact with, especially when it comes to creating databases and tables, handling constraints, and performing real-time data operations through an API.
In this article, we’ll dive into the inner workings of the database management tool, exploring the architecture and technologies that power it. Understanding how the application functions behind the scenes will give you insight into its design, how it manages databases, tables, and how the API interacts with data.

Hot on the heels of our announcement last week about our ultra-high-performance mg-dbx-napi JavaScript interface for IRIS, we are now pleased to announce a significant new technology - mg_web - which not only represents a new paradigm for JavaScript Web Frameworks, but also delivers significantly higher performance than even the fastest of the established Node.js Web Frameworks, whilst leveraging all the benefits of the big-three industry-standard Web Servers.
I'd like to announce the release of something really rather interesting - revolutionary in fact. That may sound like hyperbole, but I don't think you'll have seen anything quite like this, or even thought it possible!
We've pushed out a new JavaScript/Node.js module named glsdb which you can read all about here in detail:
You may have heard about our mg-dbx-napi interface for IRIS which provides insanely fast access from Node.js. If you've been following recent developments in the server-side JavaScript world, you'll be excited to know that mg-dbx-napi also works with Bun.js, the latter proving to be significantly faster than Node.js for many/most purposes.
Of course, if you're a Node.js user, you'll probably wonder how mg-dbx-napi compares with the Native API for Node.js that is included with IRIS.
Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.
IRIS is known to have a built-in Python bridge and even allows you to write Python server code but what about JavaScript? Let's say I need a JavaScript expression interpreter. What would you recommend as the most effective way to get one? It is highly desirable that the solution does not require administrator privileges and uses in-process communication (I mean not http and not unix-specific interprocess-communication via command line)
The last time I used CSP was back in 2008, so I am very rusty on it. This question might have been asked many times, and the answer probably is that it is a matter of preference.
Are there scenarios to which CSP pages is easier/better to use than classes extending from %CSP.Page? I want to build a little thing and don't want to start at the wrong end. Doing an API-based, heavy client-side framework is not a requirement, and I would prefer not to do it that way.
I wish to retrieve data from a cache table and then chart the results using javascript/chart.js. I have had numerous iterations of the code attempting to do this (none of which worked) and my latest iteration is shown below.
Is it possible to get a code quality stamp of approval on the Open Exchange with an application written in Javascript?
My Iris Whiz application is a browser extension written in Javascript and I wonder if having the code quality stamp missing from my application page will put people off from using it.
I got a problem to resolve, to sum it up I need to extract a function body from a JS file with cos. I already got the JS code in a string and the function name but I'm kinda stuck as to how to get my function body, I already tried a few things (regEx, counter bracket) but there are comment and strings that block them from functioning. Is there a javascript parser or a good way to do it except by creating a javascript parser?
