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.
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.
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 am excited to say that since the beginning of this year we have published many of the client SDKs for InterSystems IRIS, InterSystems IRIS for Health and Health Connect to the corresponding external repositories (Maven, NuGet, npm and PyPI). This provides many benefits to you such as:
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 -
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.
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.
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?
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;"
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.
I am struggling in understanding how FDN works within Health Share, in particular those that are related to Provider Directory within Health Share. Does anyone have examples of using FDN that they would be able share?
Given the code below, I need help with getting the collected column widths from the Demo.Configuration table and stored in the columnWidths zne page property. As I understand it, I should be able to retrieve it using zenPage.columnWidths in the setColumnWidths or dgRender clientMethods but the alert is showing that it cannot be retrieved as it shows a value of Null. Once I can retrieve those values, then I want to set the widths of the colmns of the dynaGrid according to the values in the ^Demo.Configuration table.
While working with external languages for IRIS (such as Python and Node.js), one of the first things you must accomplish is making a connection to an IRIS instance.
I’m working on a CSP application in Ensemble and want to implement versioning for JavaScript and CSS files using query strings (e.g., /js/app.js?v=1.0.0) to ensure browsers always load the latest files after deployment.
