Hi All

I this article I detail some strategic issues that a new development UI will need to address - these are the ones that I can think of now - others may come to light during this journey.

See the webinar by Eduard Lebedyuk here from the last Global Summit describing  modern web development and Caché

And, as always, if I have missed something please comment....

In .NET Core you have an option to extend a session using a "sliding expiration". This means that if over half the time has passed and the user actively uses their session then the expiry timer gets reset and the user remains logged in. This can lead to the curious situation where you have an active authenticated user with an expired access token being used in data-access requests.

I am happy to announce that InterSystems API Manager is now generally available. InterSystems API Manager (IAM) is 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.

Hello Cache Developers!  The purpose for this post is to outline a coding challenge that I have encountered when trying to use shortcuts (i.e. CTRL+G) within a ZEN application.   Allow me to provide a summarized background:

Our application has a ZEN page (call it the PPL page) with a tablepane that displays a list of records.   This page also has an iFrame (#1)

IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.

See the following link from OWASP for the definition of a CSRF attack:

https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)

Hello,

I've got a csp page that has successfully set up a websocket connection to a Cache class. When the websocket object's close function is triggered at the browser I was expecting one of the class' methods to fire at the server. The onclose method is triggered at the browser but nothing at the server. Is a method supposed to fire at the server?

Thanks,

Dan

Hi guys,

I'm curious about the development processes of those of you using Angular. 

The starting point is that, somewhere, there lives an Angular project full of (mostly) typescript files.  Eventually, those files need to be built, and the resulting built files served up to a browser.

There are several options how to deliver user interface(UI) for DeepSee BI solutions. The most common approaches are:

  • use native DeepSee Dashboards, get web UI in Zen and deliver it in your web apps.
  • use DeepSee REST API, get and build your own UI widgets and dashboards.

The 1st approach is good because of the possibility to build BI dashboards without coding relatively fast, but you are limited with preset widgets library which is expandable but with a lot of development efforts.

The 2nd provides you the way to use any comprehensive js framework (D3, Highcharts, etc) to visualize your DeepSee data, but you need to code widgets and dashboards on your own.

Today I want to tell you about yet another approach which combines both listed above and provides Angular based web UI for DeepSee Dashboards -  DeepSee Web library.

Intro

Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.

So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.   

There's only one problem:  You've never used Angular, and don't know how to make it talk to Caché.

This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.

Hello everyone smiley

I have a server configuration in a CSP Gateway installed on a PC (let's call it S2) different from the main one (let's call it S1). This configuration allows me to access a web application that is installed on S1, from a client C asking S2 for this webapp. But for now it works only in HTTP between C and S2, and we would like to use HTTPS (as it already works between S2 and S1).

Hi All

It's been 6 weeks since my original article sad
- - - - -but I have been busy on this project smiley

I have been looking at/thinking about a replacement for ZEN for around 12 months but only really started in depth 4 months ago.
Also been in IT for long enough that I can "get a feel" for a product/technology and make decisions accordingly without going into great detail. 
Any new technology has a learning curve and I don't want to waste time and effort on something that won't fly. 
And, as always, I am looking to minimise the learning curve as I want to concentrate on delivering business benefit.

Hi All
This is the index to a series of articles I hope to create over the coming months.

ZEN and ZEN Mojo are no longer being actively developed by Intesystems - this is a great shame as it is a fine product that works so well for business applications.
However ZEN is a 15 year old product and I need a path forward to replace the ZEN UI with a supported development framework.

This article is an index of the other articles I have, or plan to write. - the articles will be subject to change as I develop my thoughts and climb the learning curve.

Hi Community

I have created a simple package that allows the use of Cache with the Laravel Framework.

From my initial testing everything seems to be operating smoothly but I would like to appeal to the PHP users in the community to help me improve this package.

For those of you out there who have time and would be interested in this, please visit the repo at https://github.com/jeandormehl/laracache

Thanks in advance
