Getting Started With Angular CLI Commands

Brett Smith AngularJS, JavaScript, Programming, Single-Page Application Leave a Comment

A tool that helps the journey of learning Angular is the Angular CLI. The CLI is a useful tool that can help set up and add different elements to your projects. It follows some of the best practices that have been laid down by the Angular team, even handling some of the plumbing for you so that things will work well together.

This post shows some of the basic commands available within the CLI. We will look at some of the basic commands that can help get a project started and built, paying particular attention to the different commands and what they produce, as far as application structure and file layout is concerned…



Containers For .NET Developers

This is going to be the first post in a series of articles about modern tooling and techniques for building distributed systems. In this post, I will show how to use Docker for Windows to set up an ELK (Elasticsearch, Kibana, Logstash) server that we are going to use in future articles. The series is particularly geared toward traditional .NET developers. Let’s get started…



Creating A Custom Amazon Alexa Skill

Ryan Nguyen .NET, Programming, Tutorial Leave a Comment

With the explosion of the internet of things (IoT), many companies are competing to create the best smart home ecosystem for consumers.

Amazon Echo, for instance, is a robust system that allows the user to interact with their smart devices via voice command. Alexa is the application that the Echo communicates with, essentially the brain of the Amazon Echo. It controls how your Amazon Echo communicates with your other smart devices and services. It can sync with a variety of smart devices including switches, thermostats, garage doors, sprinklers, door locks, music streamers, news outlets, and more. It also allows the third-party companies to create custom skills which are then accessible through the Amazon Echo.

In this blog I will discuss the Amazon Echo and its Alexa application. We will go through the process to create a custom Alexa skill about the Keyhole blog, paying particular attention to keywords you’ll need to understand when you create your own Skill. From there, we’ll show how to test a Skill via simulators and deploy it to your Amazon Echo.



Real-Time Communication: Implementing Websockets With Spring Boot

Thomas Kendall Java, JavaScript, Technology Snapshot Leave a Comment

When developing web applications, we sometimes need to push server events down to connected clients. However, HTTP was not designed to allow this. To get around this limitation, a polling pattern was established where web pages would intermittently poll the server for any new events. This pattern was not ideal as it added HTTP overhead, was only as fast as the polling rate, and caused unnecessary load on the server.

Luckily, with the emergence of HTML5 came the WebSocket. The WebSocket protocol enables interaction between a browser and a web server with lower overheads. In this blog we’ll introduce the Websockets API and show how to implement Websockets with Spring Boot.
