Progressive Web Apps: The Service Worker Demystified

Adrienne Gessler JavaScript, Problem Solving 2 Comments

You can’t read any technology trend news for the upcoming year without reading about Progressive Web Applications (PWA). PWA offers the ability to add native-like capabilities to your web application.

One of the core technologies of a PWA is the service worker, so I thought I would take us through a question and answer session on service workers. Service workers have been around for a while now, but the momentum in their use has picked up with the popularity of PWA. My goal here is for you to be able to understand what a service worker is, what you can do with it, and the limitations of a service worker.

A Vue of Python

Earlier this year I blogged about creating a Lean Mean Vue Machine called Quotes on Demand. The application was a fully featured CRUD application served from a NodeJS server and had a self contained VueJS front end.

But wouldn’t it be a nice test to see if that same Vue application could switch over to another API, say something like a Python web server powered by Flask?

In this post, we will create a Python web application that will have 100% parity to an existing NodeJS web application. This will enable an existing VueJS front end to connect to the application with no additional code changes in the user interface code.

JavaScript Optional Chaining – An Introduction

Lawrence Chabela CSS & HTML, JavaScript, Problem Solving, Technology Snapshot 1 Comment

There is a new exciting feature coming to JavaScript in the not-so-far future. That feature is Optional Chaining. At this moment, Optional Chaining is in Stage 3 of the TC39 process, so it’s in late stages of the process and will be here soonish.

In general terms, Optional Chaining is an approach to simplify JavaScript expressions for accessing deeply nested values, array items, and methods when there is a possibility that a reference may be missing.

In this blog, we give an introduction to Optional Chaining in JavaScript. We discuss what problems Optional Chaining solves, the various ways you can use it, and relatable code examples.

Progressive Web App Tips and Tricks

PWA (Progressive Web App) is a powerful solution to multiple problems. Prior to PWA, there were some browser-specific implementations to some of the problems solved by PWA, but PWA is much more elegant while solving more problems at the same time.

In this post, we’ll cover the problems PWA was created to solve, some of the solutions PWA replaced, tools that make PWA development faster and more flexible, and tips to get the most out of PWA development.

React vs. Angular: A Comparison Between Two Great Options

Both React and Angular are very popular front end development frameworks. In this post, I will discuss the similarities and differences between the two, and consider when one should be used instead of the other.

React is an open-source JavaScript library introduced by Facebook to build dynamic user interfaces. It is based on JavaScript and JSX (a PHP extension) and is considered widely for developing reusable HTML elements for front-end development.

Angular is an open-source front-end development framework powered by Google. It is a part of the MEAN stack and is compatible with a large number of code editors and is considered for creating dynamic websites and web apps.

In this post, we will begin by going over the benefits of React and Angular, then break down the differences between the two frameworks using thirteen attributes. By comparing each framework side by side, it can help decide which is the best framework for your specific app project.
