Engineering problems often repeat themselves in places you wouldn't expect. Sometimes the best solution has already been invented, in a different corner of the software engineering domain. In this talk, we show how and why we mirrored the TCP/IP network stack to solve a communication problem between different components of a browser extension.

React Summit US

React Summit US 2023

This lightning talk explores how you can enrich your React projects with Web APIs. From handling data to interacting with browser features, attendees will gain insights into leveraging the power of Web APIs for an enriched and efficient React development experience to highlight the out of the box capabilities offered by Browsers.

React Advanced

React Advanced Conference 2023

Delve into the world of Web API's - MessageChannel and BroadcastChannel. Explore how these powerful APIs facilitate seamless communication in web workers, iframes, and across tabs. Join us as we uncover the techniques to enhance web interactions and unlock new possibilities. Discover the key to smoother collaboration and improved connectivity in your web projects!

High quality video encoding in browsers have traditionally been slow, low-quality and did not allow much customisation. This is because browsers never had a native way to encode videos leveraging hardware acceleration. In this talk, I’ll be going over the secrets of creating high-quality videos in-browsers efficiently with the power of WebCodecs and WebAssembly. From video containers to muxing, audio and beyond, this talk will give you everything you need to render your videos in browsers today!

Finally, Web Push API is available in all major browsers and platforms. It's a feature that can take your users' experience to the next level or... ruin it! In my session, after a tech intro about how Web Push works, we'll explore implementing smart permission request dialogues, various types of notifications themselves, and communicating with your app for more sophisticated scenarios - all done right, with the best possible UX.

In the fast pacing space of social media apps, some functionality could also be used for web applications. I am going to show you how you could use the feature flagged Face Detection API in Chrome. With a demo, we will explore the possibilities to implement face filters in your future projects. With the webcam access of a device, we add glasses by processing a video feed and using it for fun, finding that sweet spot where fun and learning come together.

Operational System allows controlling different devices using Human Interface Device protocol for a long time. With WebHID API you can do the same right from the browser. Let’s talk about the protocol features and limitations. We’ll try to connect some devices to the laptop and control them with JavaScript.

If you own an electronic music instrument made in the last 3 decades, it most likely supports the MIDI protocol. What if I told you that it is possible to interact with your keytar or drum machine directly from your beloved browser? You would go crazy, right? Well, prepare to do so…With built-in support in Chrome, Firefox and Opera, this possibility is now a reality. This talk will introduce the audience to the Web MIDI API and to my own WEBMIDI.js library so you can get rockin' fast.Web devs, man your synths!

The WebBluetooth API finally closes the gap between the browser and devices around us. And that suddenly opens up a rabbit hole, in which we inevitably encounter a few hurdles - the story of a frontend developer dipping his toes into the IOT world.

There are many ways to measure web performance, but the most important thing is to measure what actually matters to users. This talk is about how to measure, analyze and fix slow running JavaScript code using browser APIs. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Service workers bring amazing new capabilities to the web. They make fully offline web apps possible, improve performance, and bring more resilience and stability to any site. In this talk, you'll learn how these man-in-the-middle attacks on your own site work, different approaches you can use, and how they might replace many of our current best practices. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Node Congress 2022

This workshop will walk you through writing a module in TypeScript that can be consumed users of Deno, Node and the browsers. I will explain how to set up formatting, linting and testing in Deno, and then how to publish your module to deno.land/x and npm. We’ll start out with a quick introduction to what Deno is. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
