JavaScript Talks

JavaScript's Journey to the Edge | JSConf EU 2019

In September of 2008, Google’s Chromium Project released V8, a JavaScript engine, as part of a browser optimization wave that heralded the era of JavaScript browser applications that we both love, and love to hate. Less than a year later, in 2009, Ryan Dahl announced (at this very conference!) a way to run the V8 browser environment outside of the browser- Node.js, a platform that held the promise of unifying web application development, where both client and server side development could happen in the same language - JavaScript. A decade later, V8, JavaScript, and its new buddy WebAssembly, have expanded to lands charted only a few years after Node.js debuted- known (confusingly) as the “Edge”. In this talk, we’ll introduce what the “Edge” is and why we are excited for it to revolutionize computation on the web. We’ll explore how this adventurous JavaScript engine, V8, is so well suited to tasks previously limited to Virtual Machines, Containers, or even simply Operating Systems. Finally, we’ll talk about security, Spectre, and ask ourselves the age old question, “You can do it, but should you?”.

JavaScript, JavaScript…. Rocks You! | JSConf EU 2019

After so many years sitting with the computer you can take your old scratched Les Paul or Stratocaster from the case and fill all the space around with warm riffs. I’m going to show how to transform the code into Kirk Hammett’s wah-wah, Stevie Ray Vaughan’s overdrive and Kurt Cobain’s distortion. You’ll learn how to parse audio input in real-time using JavaScript and the Web Audio API. I’ll be jamming live on stage with my guitar to demo every code example and we’ll also use WebRTC to jam with friends across the world! After this talk, you will be familiar with the principles behind pedal sound effects and how to create them in code. Let’s rock the Web!

GraphQL: Towards a universal query language | JSConf EU 2019

From its friendly developer experience to its performance benefits, a lot has been said about GraphQL. Underlying it all is the GraphQL query language, made possible by GraphQL schema language. These surprisingly versatile features have the potential to provide a single interface for all modern web app development concerns. We will start with a case study on how we use GraphQL queries as an universal interface to resolve data over a variety of datasources ranging from remote HTTP requests, to local CSV files, and in-memory data stores. Next we will explore these ideas further, using GraphQL queries as an interface over the DOM and various other web APIs.

Building WebApps Like It's 1972 | JSConf EU 2019

The year is 1972 and GUI applications like no one has seen before are being built in Smalltalk: bitmaps graphics, draggable elements, drop-down menus, collapsable windows 🤯; all of them and many more coming straight from the future, powered by asynchronous message passing, object orientation, and functional programming. An unprecedented cocktail to be later rediscovered as the Actor-model. Fast forward to the present day, and typical web applications are modeled as monolithic deeply nested structures, resembling the medium the web was built for (HTML), but leaving us handicapped to build outstanding user facing applications. 🦖 Let’s explore together what we can learn from the early days of UIs, languages like Erlang and Smalltalk, the Actor-model, and how we can apply some of these principles and ideas today to take our UIs back to the future 🚀

Stencil: a built-time approach to the web | JSConf EU 2019

“We all know and love framework-like features such as hot module replacement, reactive properties, templating, CSS-in-JS, lazy-loaded bundling, etc. Stencil is a new approach, a build-time abstraction with framework-level productivity, that generates hand-optimized components using future-proof web APIs. We’ll discuss the architecture of Stencil and the innovations a compiler can introduce to your apps and design systems!
