JavaScript, often abbreviated as JS, is a high-level, interpreted programming language. It is a language which is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm.
Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.
I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.
- This can be slow/bad in applications with large data?
- It's better/recommended to use ZenReports even with ZenMojo applications?

This concept may be known to some, but I just found it very useful and I would like to share as it may help someone else.
If you are working with CSP or Zen you sometimes come across the need to use embedded JavaScript. Suppose you are working with some loops, which use < or > as shown in example below:
We have a application currently running on Zen framework, now business wants to use Angular JS as their front-end technology for any future release but they don't want to upgrade the existing the modules which are already there in Zen (as of now).
Hi Guys, I'm resending this because I sent on the weekend and looks like it has not been noticed much
I'm not that familiar in using Javascript in Zen pages, so basically we have a priting utility (app) that requires us to add a bit of JavaScript call to facilitate printing from our Zen pages as below:
So I added XData link pasted the required script, is this the correct way?
Quite a few enhancements have appeared over recent months in QEWD for easing and simplifying the creation of REST-based services. It's now even more slick and powerful, allowing you to very quickly create very high-performance, highly-scalable REST (and Web) services that make use of Cache.
I've therefore updated the training presentation deck (Part 31 on developing REST Services with QEWD). It describes all the new features with worked examples. See:

Does someone knows if any Studio version or, if in its new versions, it will be able to recognize new Javascript statements like arrow function, let, const etc ?
I have a Cache classes with %TimeStamp (e.g. 2016-04-18 12:29:11) and %Date (eg. 64027) properties. And I have a javascript client app, which needs full CRUD over this properties.
But in javascript date/time are defined by ISO8601 (e.g. timestamp 2016-04-18T12:29:11Z, date 2016-04-18).
I have been trying to implement SPA using routing between two components in a CSP page.
If i use the line which i commented the page views and gets data from the vue instance (when not using the <route-view> and other 2 vue route functions below).
since i need to implement routing i am using as below, now the property "selectedYear" is not getting data from vue instane and i am getting the below error as well.
I dont know whether i am going down the right path.

There's been quite a bit of discussion lately in this forum on the tools available in IRIS for using both XML and JSON, and debate on cross-conversion between the two formats.
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.
Most frameworks support either REST or WebSockets, and don't make it easy to switch between the two, and/or support both styles of application at the same time. WebSockets offer many advantages over REST, eg:
- most benchmarks show WebSocket messaging to be significantly faster than over HTTP
I recently added a change to our copy of zenutils.js, and while moving it up to production, I found different versions of zenutils.js. I edited a copy stored in the default directory for our web application (e.g. c:\intersystems\DEV\CSP\{application}) but the file on production is stored in {install dir}\CSP\broker.
Does anyone know how to get the closing tab/menu changing event in a CSP? I've tried the JS "OnBeforeUnload" already but it seems the browsers aren't allowing it anymore. I need to show a pop-up that holds the user if trying to get away before completing the stage.
or "So you just got yelled at by your boss, for sending him an unformatted Hello World webpage"
Our previous lesson ended with us serving a Message value obtained from a Caché REST service to the client, using Angular as a runtime. While there is a lot of moving parts involved in this process, the page is not especially exciting at the moment. Before we can start adding new features, we should take a step back and review our tools.
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).
If you read my previous post that introduced QEWD Micro-Services, you're hopefully eager to learn how to use them. So in this post I'll explain what you need to know in order to get started.
If you look in the QEWD repository, you'll find the folder:
I wrote a step by step tutorial in the qewd-howtos repository how you can write state of the art multi-page web apps with Node.js using a QEWD-Up WebSocket/REST api back-end integrated with a mainstream web framework like NuxtJS & Vue.js.
Recently I reread this article by @Bernd Mueller. It's about calling DELFATE function from zlib library. In this article I'll demonstrate several different approaches to callout libraries, we'll build the same functionality (compress function) in several different languages and compare them.
