Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In the previous part, we created a basic front-end React application. In the second part of this article series I will show how to choose the right back-end technology for your application. You will see Caché allows you to use many different approaches to link your front-end to your Caché server, depending on your application's needs. In this part we will set up a back-end with Node.js/QEWD and CSP/REST. In the next part we will enhance our basic web app and connect it to Caché using these technologies.

Bulid REST API application built with ObjectScript in InterSystems IRIS. It also has OPEN API spec, can be developed with Docker and VSCode, can be deployed as ZPM module. can be used as Overbooking System data REST api.

Hi,

Hello everyone,

I would like to know if it is possible to connect to a REST API through production, without having to write a class that extends %CSP.REST. Is there a GUI based way where I can configure my GetRest and then use EnsLib.REST.GenericService and EnsLib.REST.GenericOperation to configure my production and perform transformations?

Hi, Community!

Suppose If you develop a client js application which works with Caché server via REST API (CSP Gateway).

What are the options for Authentication and working with Caché session then?

The question is pretty much in title. I'm developing a REST API, it has a search endpoint with 10 optional parameters. How do I pass them and stay RESTFul?

To ease the question a bit let's agree that:

• all parameters are AND parameters, user can't make combos, ORs, etc. User can only provide values
• all values are integers so I don't have to think about URL limits
• all values are atomic
• all conditions are about equivalency

Some options I know of:

1. URL parameters.

As you might have heard, we just introduced the InterSystems API Manager (IAM); a new feature of the InterSystems IRIS Data Platform™, enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement.

In this article, I will show you how to set up IAM and highlight some of the many capabilities IAM allows you to leverage.

Hi Community,

I would like to present my last package OpenAPI-Suite, this is a set of tools to generate ObjectScript code from an OpenAPI specification version 3.0. In short, these packages allow to:

• Generate server-side class. It’s pretty similar to the generated code by ^%REST but the added value is the version 3.0 support.
• Generate HTTP client classes.
• Generate client production (business services, business operation, business process, Ens.Request, Ens.Response) classes.
• A web interface to generate and download the code or generate and compile directly on the server.
• Convert specification from version 1.x, 2.x to version 3.0.

Overview

OpenAPI Suite is split into many packages, and uses different developer community libraries and also public REST services. You can see on the schema below, all packages have been developed, and libraries and web services used:

I'm trying to implement Crud operation in rest services.

I'm confused about this implementation.

Is it possible to call rest services method in CSP pages?

If not means, can you tell me another way?

I need some examples or reference to implement Crud operations.

Thanks

Hi,

Hello Everyone,

We are currently in process of implementing REST APIs using IRIS and we are also looking at using Intersystems API Manager.

Our aim is to implement a Microservices Architechture where Services are small in size, bounded by contexts, autonomously developed, and independently deployable.

We are following a spec first approach where we are first defining the API specs into Swagger Hub and using IRIS API Management Service to build the REST classes i.e. the Specification class, Dispatch class and Implementation Class.

Hello.

We have a request message with properties that has underscore. This is because we need to convert that request to JSON.

The problem is when we try to assign a value in a Business Process with the editor. It doesn't work, it doesn't compile.

How can we fix this?

This is the object used in the request:

I need to redirect user to a url, which is 5000+ characters long.
To do that I set:

set %response.Redirect = url

However, in the browser I receive this header:

LOCATION: <First 3972 characters of the 'url' variable>

In WriteHTTPHeader method of %CSP.Response, where the LOCATION header is
written:

Write "Location: ", <Redirect>,!

After I added a buffer flush, after the above-mentioned line:

Hi everyone,

I have a project which requires the sending of JSON messages to an external service provider using REST. The service provider requires the message contents to be signed.
