Intro to Angular 2 – Part 6 – ServiceWorkers

In the last installment we learned how to run JavaScripts over different threads by using WebWorkers. This time we’ll go a few steps further and learn how to use ServiceWorkers to achieve not only separation of code but also to build up client-side proxies. These proxies are the most important building blocks of so-called Progressive Web Apps as they allow web apps to function under rough conditions like slow bandwidths or broken connections. ServiceWorkers can also be used for push-based services or background synchronization as they run completely detached from the Browser DOM. A ServiceWorker is basically a SharedWorker with super-powers. However, the […]

Writing MicroApps with the FlyWeb API

Just a few days ago, Mozilla announced a new Web API called FlyWeb that enables web pages to host web-servers that can expose their services to nearby browsers. With FlyWeb one can easily create discoverable services. Unlike with traditional HTTP users aren’t actively searching for services or content but instead let their browser accept mDNS announcements sent from nearby servers that implement the FlyWeb API. A server implementing this API is equally capable to deliver web pages like any other but it doesn’t have a DNS entry or IP address. Instead, certain announcement packets will be sent after the user has accepted to create and […]

Introduction to Angular 2 – Part 3

In this article we’ll learn how to use the successors of former Angular 1.x filters: Pipes. As most of us know from own experience the data our apps consume is usually available in various formats that don’t fit very well to our (internal) processes. Also there are situations where we want to check some values first before going any further. And it’s not a big secret that from user’s perspective working with data via complex forms and numerous input fields would quickly become very cumbersome without all those nice little helpers like text formatters, syntax checkers, numeric converters etc. In this […]

Introduction to Angular 2 – Part 2

Two weeks ago I wrote the first article for this series and I think it ended up being a chaotic bag of words filled with a myriad of different topics, examples and way too many screenshots. This happens when you learn something completely new instead of doing some more creative stuff on a weekend. Therefore, I’ll now focus this article on @Input, @Output and EventEmitter from Angular 2 rc1. Less is more and I’m planning to talk about other Angular 2 parts in further articles. But to effectively learn how to use a framework is always a question of practice than everything else […]

Introduction to Angular 2 – Part 1

It’s been a while since I wrote anything here. But this blog isn’t dead or in ‘maintenance mode’. I’m just coming back from the trenches of web development and, as always, things are getting messier every day. So many new frameworks and ‘very-cool-best-practices one should follow’. However, with or without JavaScript fatigue let’s do something new and learn a few bits about the upcoming Angular 2. And just to make a few things clear: I’m not an experienced Angular developer and everything I show and explain here is based on my 2-day experience with the current Beta (today’s my second day). […]
