#Node.js

5

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

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.

Hey Community,

Learn how you can develop a Node.js application and connect to InterSystems IRIS data platform through the Native API:

I'd like to announce the release of something really rather interesting - revolutionary in fact. That may sound like hyperbole, but I don't think you'll have seen anything quite like this, or even thought it possible!

We've pushed out a new JavaScript/Node.js module named glsdb which you can read all about here in detail:

Searching the developer community for the string "node.js" leads to navigating to the following URL: https://community.intersystems.com/search/all/node.js for which the browser receives the "404 NOT FOUND" error response. The behavior is consistent for any search string ending on ".js" or ".css" (not sure whether there any other suffixes affected). Please fix the DC to handle such search strings appropriately.

Node.js fails to open database

Hi,

My attempt to run a node.js command fails at the open command with a "Error loading Cache Library: C:/InterSystems/Cache2018/bin/cache.dll; Error Code 126 (The specified module could not be found.)" result. I can't argue with the error message as the cache.dll file doesn't exist. Apparently I missed an installation step. Could somebody point out what it might be please.

Version: Node.js Adaptor for Cache: Version: 1.1.136a (ABI=48)


Cache for Windows (x86-64) 2018.1.4 (Build 504) Thu May 14 2020 14:31:34 EDT

QEWD-baseline

Hot on the heels of the QEWD-JSdb announcement, QEWD-baseline provides a ready-to-run baseline environment for developing REST APIs.

The QEWD-baseline repository (https://github.com/robtweed/qewd-baseline) includes a fully-detailed tutorial on how to build RESY APIs using QEWD and the QEWD-JSdb database (running of course on IRIS).

https://github.com/robtweed/qewd-baseline/blob/master/REST.md

Included in the tutorial is:

The latest WebComponent-based, SB Admin 2-themed QEWD Monitor application now includes a cool D3-based viewer for visualising your IRIS or Cache Globals - see example below

This qewd-monitor-adminui application is automatically installed when you install QEWD on a Windows machine

See here for details on installing QEWD on Windows:

I am a newbie who is trying to learn how to set up a basic connection to Iris using a node js application. I am astounded at the lack of documentation there is on how to do this and even more concerning there are a few errors within the documentation. For example I am on the Native API application within the below link.

Hello,

In response to the infrastructure needs of our company's service, I've created a small API that sends SNMP queries to InterSystems to visualize relevant data for retrieval when the infrastructure implements monitoring.

However, I'm experiencing a timeout issue when attempting to collect information using an SNMP walk. Here is the code for my API's SNMP service:

You may have heard about our mg-dbx-napi interface for IRIS which provides insanely fast access from Node.js. If you've been following recent developments in the server-side JavaScript world, you'll be excited to know that mg-dbx-napi also works with Bun.js, the latter proving to be significantly faster than Node.js for many/most purposes.

Of course, if you're a Node.js user, you'll probably wonder how mg-dbx-napi compares with the Native API for Node.js that is included with IRIS.

I'm using a customised IRIS Community Edition Docker Container: Node.js has been added and the Native API for Node.js directory moved to a node_modules folder in /home/irisowner. I've changed the _SYSTEM password using the Management Portal (which connects to IRIS just fine)

If I shell into the running container and try to connect with a JS script file containing this:

const IRISNative = require('intersystems-iris-native');

let connectionInfo = {

host: 'localhost',

port: 1972,

ns: 'USER',

Introducing mg_web

Hot on the heels of our announcement last week about our ultra-high-performance mg-dbx-napi JavaScript interface for IRIS, we are now pleased to announce a significant new technology - mg_web - which not only represents a new paradigm for JavaScript Web Frameworks, but also delivers significantly higher performance than even the fastest of the established Node.js Web Frameworks, whilst leveraging all the benefits of the big-three industry-standard Web Servers.
