Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, called RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.
I just want to share with you the knowledge aka experience which could save you a few hours someday.
If you are building REST API with IRIS which contains more than 1 level of "/", e.g. '/patients/all' don't forget to add parameter 'recurse=1' into your deployment script in %Installer, otherwise all the second and higher entries won't work. And all the entries of level=1 will work.
/patients
- will work, but
/patients/all
- won't.
Here is an example of CSPApplicatoin section which fix the issue and which you may want to use in your %Installer class:
The first installment of this article series discussed how to read a big chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a class. The second installment discussed how to send files and their names wrapped in a JSON format.
Now let’s look closer at the idea of sending large files in parts to the server. There are several approaches we can use to do this. This article discusses using the Transfer-Encoding header to indicate chunked transfer. The HTTP/1.1 specification introduced the Transfer-Encoding header, and the RFC 7230 section 4.1 described it, but it’s absent from the HTTP/2 specification.
I've enabled the JWT Authentication in my web application. I invoked the /login page to get the JWT and it creates an entry in %SYS.TokenAuth table. Is there any time span for the entries will rid out from the table automatically or It's a manual process? Where can I find the JWT signature private/public key
In our last lesson, we added a form to Edit our existing Widgets, and save them back to the server. However, our Form was not well structured and our Save button had no intelligence, and was not fully visible. So today, we will apply some Material components and Angular style to make the form more useful
QEWD is assumed by most people to only integrate with IRIS (or Cache) via a connection through IRIS's high-performance C interface. This requires QEWD (and its Node.js environment) to be installed and configured on the same machine as IRIS.
I'm frequently asked if QEWD can run on a separate server (or servers), and access IRIS (or Cache) over a network connection. The answer is yes it can, but the information on how to set it up in this way has been admittedly a bit tricky to discover.

I'd like to briefly announce three new packages, available on the Open Exchange / through ZPM, that can really help accelerate modern full-stack application development on IRIS. I announced all of these in a Global Summit session last week, but you may have missed it - and I hear there's a full-stack application development contest coming up!
In our last lesson, we added some formatting and validation to our Edit Widget form. So, now we are ready to add the ability to add new Widgets to our application. However, the great Widget Wars have come to an abrupt end, as Widget Direct has purchased its biggest competitor, WorldWideWidgets. In order to maintain some continuity, we need to display their catalog on our new application.
