Making a Game with Rx.js and Web Speech at Active Dublin 2016 - Part II

In the last article of the series we started building a game Rx.js and Web Speech just like I did at the JavaScript hackathon at Active Dublin 2016.

The game is a variation of the popular typing game where words fall off the screen and you need to type them before they get to you. The slight variation consists in changing the game mechanics from typing to speaking. In our game, letters will fall off the screen and the player will need to say a word starting with that letter to earn points, destroy the letter and avoid certain annihilation.

At the end of the last article we had completed the beginnings of a game with a beautiful black background and some letters falling off the screen. Let’s continue building our game by adding some player interaction through the Web Speech API!

Making a Game with Rx.js and Web Speech at Active Dublin 2016 - Part I

Last week… or was it two weeks ago?… wo! Time flies!… Two weeks ago I was at Active Solution spring conference at Dublin. The topic of the conference was JavaScript (yippiii!) and we organized a hackathon for all employees to experiment with their JavaScript skills and build something cool over the weekend using music, sound or speech APIs.

It was a super fun experience and every team had something to show at the final reckoning in the demo sessions. My personal favorite (and the winner) was a virtual fly that sprang to life when you connected several devices together and started buzzing as it randomly flied through a crowded room to everyone’s delight (or almost everyone XD).

I, myself, worked as a coach during the Hackathon so I couldn’t fully participate with any team. I did sneak some hours though and attempted to build something cool with Rx.js and Web Speech.

This is the story of… Say What Maddafackaaaaaaa!! - The Game… Behold!!

A look at ES6 Maps

The Mastering the Arcane Art of JavaScript-mancy series are my humble attempt at bringing my love for JavaScript to all other C# developers that haven’t yet discovered how awesome this language and its whole ecosystem are. These articles are excerpts of the super duper awesome JavaScript-Mancy book a compendium of all things JavaScript for C# developers.

ES6 brings two new data structures to JavaScript, the Map and the Set. This article is devoted to the Map, which is fundamentally a HashTable and which we often refer to as Dictionary in C#. JavaScript’s Map provides a simple API to store objects by an arbitrary key, a pretty essential functionality required in many JavaScript programs.

Getting Started With Rx.js: A Gentle Introduction

The first talk about Reactive Extensions I listened to was in 2010 at a .NET conference in Sweden. Back then it looked like an awesome way to write ultra-responsive (in the fast-to-respond sense) WPF applications. I watched in awe as the speaker demonstrated how to magically orchestrate a throng of diverse asynchronous operations into one beautiful, declarative and concise set of instructions.

I watched it then, admired it and never saw it again, never used it myself, not even once. Yep… that happens sometimes :)

Fast-forward to today and it feels like Rx.js is exploding (EXPLODIIIING!!!), with frameworks like cycle.js that let you build applications right on top of Rx.js or Angular2 that has chosen Rx.js as its core async pattern.

But what is Rx.js, why is it so popular and ever so useful?

Getting Started With Angular 2 Step by Step: 6 - Consuming Real Data with Http

UPDATE (22th May 2017): This tutorial has been updated to the latest version of Angular (Angular 4). Note that the Angular team has re-branded the terms Angular 2 to Angular and Angular 1.x to AngularJS which are now the official names of these frameworks.

This is the sixth article on the Getting Started with Angular 2 Step by Step series if you missed the previous articles go and check them out!

Angular 2 Getting Started

Good day! Today we are going to wrap up this introductory series to Angular 2 with a look at how to retrieve real data from a web service using the http module in Angular 2. We’ll also learn a little bit about Observables and Rxjs (the new async weapon of choice in Angular 2) along the way.

Let’s get started!
