Azure Communications Voice Calling QuickStart

This entry was posted in Azure javascript and tagged azure communication services quickstart voice call on by

In this post, I’m going to walk you through the process of getting started with adding voice calling into your apps using Azure Communication Services (ACS). If you haven’t read my previous post or watched my video on “What is Azure Communication Services?” I’d recommend doing that first so that you understand what ACS is all about and the key features it offers. In a nutshell, ACS allows you to add voice, video, chat, SMS, and other telephony features into your applications. It can be used in web apps, desktop apps, or mobile apps. The ACS docs have a Calling […]

How many times have you tried to contact a company’s customer service department only to waste time looking up the phone number or trying to find the *right* phone number to ask a simple question? Once you finally get through to someone you typically end up switching between the phone app and the company’s website or app to pass along required information to the customer service representative. It can be frustrating. Wouldn’t it be easier to open the company’s website or app and make the call directly from the screen that has all of your information already available? For example, […]

You’ve probably heard the old adage, “Change is good” at some point in your life. Although change can be hard, I’ve found that for me personally, it’s the only way to grow and move forward in life. It was a big (and hard) change starting my own company 20 years ago but I wouldn’t trade the experience I’ve gained for anything. To set the stage for this post, let me share a little about what I’ve been doing, walk you through what I’ve been thinking, and then discuss the next big change I’ve decided to make (jump to the bottom […]

Using the Kubernetes JavaScript Client Library

This entry was posted in javascript kubernetes Node.js TypeScript and tagged deployments services on by

I’ve been working with Kubernetes a lot and focusing on various deployment techniques that can be used (such as Blue-Green Deployments) for a Pluralsight course I’m creating called Kubernetes for Developers: Deploying Your Code. If you’re new to Blue-Green Deployments, here’s a quick overview: While I was working on the course, Dr. Christian Geuer-Pollmann and I had chatted on Twitter about a Blue-Green dashboard he wrote. He did a great job on it! I’ve been wanting to experiment with the JavaScript Kubernetes Client library so I decided to see what could be done to create a simple Blue-Green Deployment “dashboard” […]

Enabling Metrics Server for Kubernetes on Docker Desktop

This entry was posted in Docker kubernetes and tagged docker kubernetes metricsserver on by

Lately we’ve been working on a new Docker and Kubernetes instructor-led training class that we’ll be running onsite at several companies this year. The class uses Docker Desktop and the Kubernetes features it provides for several of the chapters. We needed to get the local cluster students will use to match as closely as possible to a cloud-based Kubernetes cluster that would be found on Azure, AWS, or GCP. The class covers using AKS as well, but most of the lab exercises rely on Kubernetes in Docker Desktop so running key features like the dashboard and Metrics API was important. […]

Observable Store – Now with Support for the Redux DevTools

This entry was posted in Observable Store and tagged debugging front-end state redux devtools state management on by

Observable Store now supports extensions! These can be added when the application first loads by calling ObservableStore.addExtension(). The first built-in extension adds Redux DevTools integration into applications that use Observable Store. The extension can be found in the @codewithdan/observable-store-extensions package. If you’re new to the Redux DevTools, they can be used to “time travel” through your application to see what happened at particular times. This feature is extremely useful when you’re trying to track down a problem or simply want to see what state flows through your application. You can get more details on the various Redux DevTools extension features […]
