I'm trying to set up VS Code for ObjectScript using the instructions found here. I've got both Cache 2018.1.2.309.0 and IRIS 2020.1.0.215.0. When I try to connect to either one of them the connection fails, and I get a notification in the bottom right corner that says "Unexpected token < in JSON at position 0". I've checked the JSON settings file that VS Code uses, and they're fine and formatted properly. All of the settings I've entered are correct.
Let's imagine if you would like to write some real web application, for instance, some simple clone of medium.com. Such sort of application can be written using any different language on the backend side, or with any framework on the frontend side. So many ways to do the same application, and you can look at this project. Which offers a bunch of frontends and backends realizations for exactly the same application. And you can easily mix them, any chosen frontend should work with any backend.
Let me introduce the same application realization for InterSystems IRIS on a backend side.
I am trying to find out if it is possible to decode the Azure access token in IRIS. Has anyone ever tried this before? I need to decode the token to extract the "Scope" details in order to verify the scope to make sure client is permitted to do the request they have done.
If you could point me to any information, that'd be great.
Hello! I have a question how to parse Library.ListOfObjects to JSON
I send post data like this from client using rest and want parse "templates", after save "codeForm","codeName" in database
{
"whoIs": "",
"templates": [{
"codeForm": "FORM_FIOGROUP",
"codeName": "operationDate",
"orderNumber": "1",
"codeFormat": "YYYY-MM-DD",
"header": "DATE",
"dbfFormatType": "Date",
"dbfFormatLength": "8",
"valueFrom": "Payment"
}, {
"codeForm": "FORM_FIOGROUP",
InterSystems IRIS 2019.1 has been out for a while and I would like to cover some enhancements for handling JSON which might have gone unnoticed. Dealing with JSON as a serialization format is an important part of building modern applications, especially when you interact with REST endpoints.
I am creating an import tool to convert a client's JSON data into IRIS classes. The sample file is over half a gig. I am copying the data into an instance of %Stream.FileCharacter;. My first few attempts worked fine. However I started getting an error thrown when I try to create a DynamicAbstractObject using the %FromJSON method. See the code below. The error code given is not in the documentation, at least not the doc that I was searching.
I had a challenge recently where I was asked to parse and iterate JSON to find a patient that has a forename = "Bill" and try to make the function that iterates through the code re-usable.
Being working in Healthcare there isn't much experience or demand for parsing JSON, as most of my work is HL7.
I took this on using the documentation and worked out a way to parse the JSON (see posts below for code and source data).

There's been quite a bit of discussion lately in this forum on the tools available in IRIS for using both XML and JSON, and debate on cross-conversion between the two formats.
I am trying to write a REST consumer the API that I am talking to expects a file to be sent over and in response I will get a file back if anyone out there has ever had a similar use case please could you kindly guide us or share some sample code please
I would like to offer my services as an Intersystems Professional and am available to work on projects.
I have more than a decade experience into Intersystems stack of technologies including IRIS, Ensemble, Healthshare, Healthconnect, Cache Objectscript, Mumps, Zen, Analytics etc. with companies spread over US and UK involved in multiple domains.
I'm looking for some help with JSON notation for a global structure. I need a way to represent a global structure in JSON where the global structure both has a value at a given node as well as sub-nodes.
It's been 6 weeks since my original article - - - - -but I have been busy on this project
I have been looking at/thinking about a replacement for ZEN for around 12 months but only really started in depth 4 months ago. Also been in IT for long enough that I can "get a feel" for a product/technology and make decisions accordingly without going into great detail. Any new technology has a learning curve and I don't want to waste time and effort on something that won't fly. And, as always, I am looking to minimise the learning curve as I want to concentrate on delivering business benefit.
Has anyone used the ##class(HS.JSON.Path).%Evaluate() classmethod interrogate JSON and return a specific object value? I need to extract the MessageHeader.destination.endpoint value from a FHIR bundle and can't seem to get that XPath-like method to work.
We are working with a vendor who only accepts JSON as payload. We are currently still on Cache/HealthShare, not IRIS. Since we have to send Continuity of Care Documents, this raises issues with Long Strings (some CCDs can be quite large and in addition to that, they have to be b64-encoded which increases their size even more).
My question is: if we were to go on IRIS and use %JSON.Adapter, storing the encoded Stream in an object's Stream property, would calling %JSONExport() on this object produce the desired JSON? Or would we have to call %JSONExportToStream()?
Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.
What is the best option to disable that? I need here a empty String and not /x00.
What is the best way to create an HL7 message from JSON input file?
We have JSON file available with data required for building the HL7 message . I am trying to use a standard file/FTP Business service to pick up the file and convert the input %FileCharacterStream into a dynamic Object and use the stand JSON features to read /process the data and build the HL7 message.
Is there any other better way to do this? or any standard built-in functionality available in HealthShare?
Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. Previously, I outlined the basic steps to install and connect Node.js to Caché and make it's powerful multi-model database capabilites available for use with Node.js. You can use Caché as a NoSQL-, document- (with unique key-level access!), SQL- and object-database with Node.js. When developing JavaScript applications, you'll see how powerful this combination is and makes Caché a perfect fit for Node.js.
In the first part of this article series I will show how to get started with the React framework, one of the most popular frameworks currently taking over front-end development. In the next parts you'll learn how to connect a basic web app to a Caché back-end.
You'll see, it's very easy to get started with this technology - you can even compare the amount of basic knowledge you need to COS because you only need to know a few basic concepts to start!
