#REST API

Hi Developers!

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2.

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

Recently i've been using Restforms2 to create a CRUD API for a project. But it lacks some advanced functionality that we need, so we have created a production with a REST WS which handles those advanced methods. That works great but there's a drawback, it does not have authentication.

I would want to use the same authentication method as Restforms2 which is a basic auth using IRIS users and passwords.

We have created a number of REST adapters that extend %CSP.REST and these have been working fine. However, we are now facing a problem with a new one where very large XML documents are being posted. This is the pattern we are following:

Set inMsg = %request.Content.Read()

Applications that work with bill payments and receipts, as well as the delivery and inventory of items, generally require the use of barcodes or QR Codes. The latter is used in even broader scenarios since the QR Code can store more information than a simple bar code. Thus, it is important to have the ability to generate barcodes and QR Codes or read the data stored in them from an image or a PDF. This article will show you how to do this using Python and some of its free libraries.

Hi Developers,

In this article, I’d like to present details of which technologies we had been using to develop our application for the IRIS for Health Contest:

When using the REST API classes for building services on a spec-first approach, the implementation class methods are usually built this format:

ClassMethod <method-name>(body As %DynamicObject) As %Stream.Object

But sometimes it keeps building the endpoint implementation method like this:

ClassMethod <method-name>(body As %Stream.Object) As %DynamicObject

It has been a problem because the rest of my implementation rely on the fact that the "body" object is a DynamicObject.

I have a REST Service that I want it to receive a json string request I have set up my URLMap as follows the top URL when populated and requested works fine but I would like my request to be a json string and that is not working I am getting a 500 error am I missing something please advice.

I cloned iris-interoperability-template for my app interoperability-test. I wanted to develop an app to test interfaces in Interoperability productions.

Hello Community!

This article gives an overview of the REST JSON webservices developed for TrakCare.

These webservices allow users to access TrakCare data from outside of the software, mainly through external apps.

They are developed in REST with ObjectScript, and they allow data access in four modes:

What are other's thoughts, opinions and experiences going from CSP to RESTful services, specifically when it comes to reusing code in CSP files?

One could define a method in CSP as follows:

<script language="cache" method="SubmitSomethingAwesome" arguments="aswesomeId:%Numeric">

And it's generated in csp.mycsppage.cls ascsp.mycsppage.SubmitSomethingAwesome(awesomeId as %Numeric).

Have people had success defining there rest call by calling the generated CSP classmethod?

Things that work well I've found:

In this article, I would like to talk about the spec-first approach to REST API development.

While traditional code-first REST API development goes like this:

• Writing code
• REST-enabling it
• Documenting it (as a REST API)

Spec-first follows the same steps but reverse. We start with a spec, also doubling as documentation, generate a boilerplate REST app from that and finally write some business logic.

This is advantageous because:

• You always have relevant and useful documentation for external or frontend developers who want to use your REST API
• Specification created in OAS (Swagger) can be imported into a variety of tools allowing editing, client generation, API Management, Unit Testing and automation or simplification of many other tasks
• Improved API architecture. In code-first approach, API is developed method by method so a developer can easily lose track of the overall API architecture, however with the spec-first developer is forced to interact with an API from the position if API consumer which usually helps with designing cleaner API architecture
• Faster development - as all boilerplate code is automatically generated you won't have to write it, all that's left is developing business logic.
• Faster feedback loops - consumers can get a view of the API immediately and they can easier offer suggestions simply by modifying the spec

Let's develop our API in a spec-first approach!
