Making Regular Expressions Simple With VerbalExpressions

Chris Berry JavaScript, Problem Solving, Tutorial Leave a Comment

Regular expressions are not the easiest thing in the world to quickly understand. Most developers only work with regular expressions when they really, really have to.

But what if there was another way?

There is and it’s called VerbalExpressions. VerbalExpressions is a collection of over two dozen repositories and libraries that use plain and simple language to describe a regular expression. In fact the motto they use is, “Regular Expressions made easy”.

VerbalExpressions is a quick and easy way to write complex regular expressions. In this blog, I will use the VerbalExpressions JavaScript implementation as my library of choice to demonstrate this great tool to you.



Getting Started With Angular CLI Commands

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…



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.



A Test-Driven Development Introduction to Angular 2 – Part 2

Matthew Brown AngularJS, JavaScript, Single-Page Application, Technology Snapshot, Testing 5 Comments

In this updated blog post, we’ve built an employee directory using Angular 2 with unit tests, gone over some differences between Angular 2 and version 1, and introduced some of the features of TypeScript.

I originally wrote this article/application when Angular 2 was still in beta. Now that it has released officially, I have updated the source code to reflect updates made to the Angular 2 framework for release. My approach to get this working was to start from the new Angular 2 quick-start project, port in the original application source code, and refactor as needed to make things work. Let’s get started…
