#Node.js

4

Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code server-side.

There's a new and exciting enhancement to QEWD that has just been released - it's an additional layer of abstraction known as QEWD-Up. QEWD-Up hides away all the mechanics of QEWD itself, allowing you to focus on just your REST APIs and the code that implements them.

Additionally, and importantly, QEWD-Up simplifies the maintenance of your REST APIs, allowing you (and others) to quickly and easily understand their life-cycle and implementation.

If your looking to develop a Node.JS to Caché library then you might want to consider using a pure TCP connection with a custom message transport protocol. This bypasses the native Caché connector libraries that can get stale with a new release.

Node.JS is very good at non blocking code development, so building a performant solution isn't that complex.

iris.node not found

I followed the instructions in the documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls... (Install iris.node on nodejs for windows). Procedures made:

=> Copy iris.node to the location specified in the NODE_PATH environment variable: C:\Program Files\nodejs

=> I used: var irisobj = require('iris') on my js file

But is not work. Error: The specified procedure could not be found.

Introduction to QEWD Micro-Services

In my previous posting about the new support in QEWD for JSON Web Token (JWT) support, I mentioned that it was a key step in enabling Micro-Service support in QEWD. In this post I'll give some background to how they work and the thinking behind them.

If you haven't heard about Micro-Services and/or want to learn more, there's lots of information available if you do a Google Search. Here's a good starting point:

Hi,

If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:

Node.js version

Does anyone know where to find a cache.node that works with Cache version 2016.1.1.108.0? I am currently getting this:

Error: Unable to load shared library C:\InterSystems\TryCache\bin\cache.node''

I am using Windows 7 Pro + SP1.

Thanks!

Those of you who are following the FullStack competition here in the Developer Community will know that I submitted an entry named qewd-conduit. I wanted to summarise why I think it's something worth you taking a bit of time to check out.

qewd-conduit uses the Node.js-based QEWD framework alongside IRIS to implement the back-end REST APIs for something known as the RealWorld Conduit application:

Newbie

I am currently running a docker image with Iris 2021.1 and I would like to install node js on to it. I have had a look at the instructions on the intersystems online learning portal and I must say its very confusing. Some of the documentation says that you can only install it on 2019. Other parts say that it doesn't matter and you can install it if you have a dev directory. I checked my dev directory and there it isn't there. Sadly this is very inconsistent. Does anyone know if it is possible to install on the above mentioned version of Iris ?

Having your Node.js Cake and Eating It Too

I've mentioned the QEWD project in this group before: it's a Node.js-based platform for web, Native and REST applications which tightly integrates with Cache. It uses a somewhat different philosophy to the use of Node.js than the norm, and I've now published an article that explains this approach and the unique benefits that arise as a result.

It turns out that, integrated via QEWD, Cache is an ideal bed-fellow for Node.js. QEWD makes the integration of Cache and Node.js exceptionally fast, simple and intuitive to use, but also extremely powerful.

HI,

I am planning to build a WebApp that will have tons of data to display in tables, ability to add comments on that table rows and may be some few more small features as we move on.

1. It has to be Secure

2. It has to be fast

3. It has to be Non CSP / Non Zen

4. Will have Cache DB to pull records from but should be flexible to do that from any odbc resource

5. Version 2018 Ensemble

My first step would have been to investigate different options for technologies that would make it work and best suited with Ensemble 2018

Hi Developers,

Please welcome the new video specially recorded by InterSystems Product Manager @Bob Kuszewski for the 3rd InterSystems Online Programming Contest on InterSystems IRIS Native API:

What’s the contest about?

In the last year, InterSystems added and expanded Native APIs for Java, .NET, Python, and Node.js. The Native API provides high speed access to globals, the ability to instantiate and use ObjectScript objects, and fine-grained control over transactions.

iris.node download

Hi,

I want to test the node.js interface to iris with trial sandbox. The node.js documentation refers to get de node package from the instance bin directory. As I'm trying to use the trial sandbox I don't have access to the directory. Please let me know where I could download iris.node package.

Thanks,

Fabian

Hey Intersystems Community,

I have a Problem with the Session Handling in .csp.

I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.

After that the Web Service response is in JSON.

I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html.
Everything Works Fine with the session Handling via Cookie.

Hi Developers!

This is the second post on the resources for Developers. This part is about Open Exchange

Using Open Exchange to Learn InterSystems

InterSystems Open Exchange is a applications gallery of tools, connectors, and libraries which InterSystems Developers submit to share the experience, approaches and do business. All the applications are either built with InterSystems data platforms or are intended to use for development with InterSystems data platforms.

If you are a beginner developer you can take a look at applications in Technology Example category. All the applications in this category come with open source code repositories, so you are able to run the samples and examples in a docker container with IRIS on your laptop or in the cloud IRIS sandbox. Examples:
