  • Playing around with the Gamepad API

    The Gamepad API gives you the ability to deliver console-like experience for the desktop users. You can create JavaScript applications and HTML5 games that can be controlled using the gamepad - how cool is that? Every device with a browser can be turned into a game console and with the Gamepad API support we can build HTML5 games like never before. It's easy to implement, do not require any plugins to run in the browser and is simple as just plugging in your device and playing the game right away. Now is the best time to learn how to use it in your next HTML5 project!

    Gulp, as a better Grunt? Automate your frontend development workflow fully!

    Let's quickly describe all the pros of having your development workflow automated and show the pros and cons of advanced grunt setup.

    Then we'll switch to Gulp - a new and pretty decent tool, with a very quick, easy and clean way to being configured. As a summary: I want to show all the things we can [and should have] configure as a current frontend developer. That is, f.e.: code linting, additional syntax compilation (coffee/jade/sass), files compression, adding comments, compiling fonts/vectors, unit/integration testing, CI, deployment, multiple environments configuration.

  • Mobile HTML5 Game Development: design for performance.

    My talk will guide the listeners through my yearly trip as a HTML5 mobile game developer. I will focus on the performance side of it: optimising the canvas to fit multi-resolutions devices, asset management, physics engines in javascript, mobile wrappers (cocoonJS and Ejecta), a little about the alternatives: CoronaSDK and SpriteKit with Swift, and finally I'll answer the question: "Can we make a living as HTML5 game developers?"

    Effective SVG icons management system

    Aim of the talk is to show how to manage icons in your web app. I'll introduce you to the concept, walk through configuration and highlight some ways of going even better.

  • Get Practical with Web Components

    This presentation shows web developers how to build next-generation web apps using various Web Components (native and Polymer framework). Web Components (HTML Templates, Shadow DOM, Custom Elements and HTML Imports) are the highlight of current web standards development, with Google and Mozilla pioneering the implementation of the specification draft. While numerous presentations all over the world have introduced Web Components to web developers, not many have demonstrated the practical aspects. This presentation will use existing tools to show web developers how they can make next-generation web apps using custom HTML elements from a wide spectrum of vendors – from giants such as Google to open-source enthusiasts on GitHub.

    Boilerplate-B-Gone - do it yourself syntactic sugar with sweet.js

    Have you ever written the same snippet of code over and over again, just because the framework or the library that you use demanded it?

    JavaScript can be a pretty verbose language at times. Some libraries like React.js counter this by extending JavaScript syntax, but most others do not. Sweet.js is a library created by Mozilla, which allows you to extend JavaScript on your own.

    In this talk you will learn how to write JavaScript macros and see some useful real-world examples of where they can be applied.

  • Let It Flow - Introduction to Functional Reactive Programming

    When JavaScript Scripts evolved into JavaScript Applications, "Callback Hell" and "Spaghetti Code" went into the common dictionary of front end programmers. Asynchronous programming is incredibly complicated and hard to maintain, even to experienced developers. I would like to take you to the functional world of events, streams and signals and propose an alternative approach. During the presentation, I will gently present what the Reactive Programming is and how you can introduce it into your daily workflow.

  • Douchebag Programmers - Our Image?

    Are we really team players and good developers? - Very subjective and almost serious talk about how uncooperative sometimes we are, and how we're seen among other developers, clients, and people not related to software development.

    Let’s talk about front-end performance

  • WebRTC - so much more than just video conferencing

    WebRTC allows us to create peer-to-peer connections between browsers. Most people think of it only as an API that enables plugin-free video calls, but it's actually much more powerful and versatile.

    In this talk I'll show you a few interesting WebRTC projects and how easy it is to create your own apps using this API.

    Szymon Nowak
  • Clientside localization in Firefox OS

    Firefox OS required a fast and lean localization method that could scale up to 70 languages, cater to the needs of hundreds of developers worldwide all speaking different languages and support a wide spectrum of devices with challenging hardware specs. In this case-study I'll show how we were able to create a localization framework which embraces new web technologies like web components and mutation observers, how we came up with new developer tools to make localization work easier and what exciting challenges lie ahead of us.

  • Ampersand.js – Minimalistic approach to not so minimalistic problems

    When frontend developer plays around with some new framework or tool and creates a new useful web app or highly entertaining game it usually lands in his code repo at least or at his blog post at most. To often we put our private code on a shelf, because it's either not clean enough, not well tested or maybe because we are to afraid to give our apps to the users. This presentation aims in showing how an idea inspired by my nephew's school assignment evolved into one web application, then into the second and third one and how I monetized them. I'm gonna show how I embedded AdMob advertising and AdSense into web applications that were published for Android, FireFox OS and Chrome OS. I will show what techniques and ideas I used to keep my income at a reasonably high level. I will give a few tips on how to constantly attract new users and keep the old ones and how to look forward into new mobile markets. All those web applications are described in details here:

What is Meet.js?

Meet.js is a free front-end meetup organized by web enthusiasts in 8 major Polish cities - Warsaw, Gdańsk, Poznań, Wrocław, Cracow and Katowice, Łódź, Szczecin. The idea was formed by Damian Wielgosik (Front-Trends, Falsy Values) in January, 2011. We believe it is very important to engage local communities in sharing the Open Web knowledge focusing mostly on JavaScript and HTML5. Open Web knowledge makes people develop fast and improve their skills.
