What does shape the current state of Web Design? How can we leverage CSS to support the art movement on the Web?
Let’s dive into art direction and trends to find a new way to express our design ideas in CSS. During my talk you will find more about the intersection of CSS code with collages techniques, anti-design aesthetics and much more. Everything will be combined with practical CSS and many examples you can use on your websites right away. I will be presenting some of my CSS experiments to show you that art has a true impact on CSS properties and new features.
Find your inner designer and join me on this artistic CSS journey.

Agnieszka is a coding designer with a strong focus on UX-related issues, currently working at Adobe in Warsaw, Poland. She is the co-founder of The Awwwesomes an initiative teaching how to create awwwesome things on the Web, organizing coding & UX workshops for beginners, co-organizing conferences (Front Trends 2018 and Element UX Talks) and meetups in Poland.

Designing components for fun, profit and sanity

Yishu See @yishusee

In recent years, web applications have largely converged to a modular approach, where self contained components make up the basic building blocks of an app. Components have offered us a way to logic in bite size digestives but they can also grow to become huge unwieldy monsters.
Imagine you find yourself five years into a project, in a team of 10, over a thousand components, and a chance (albeit daunting task) to start with a fresh codebase. How would you begin designing the components?

Yishu is bad at things. Bouldering, speaking Japanese, crow pose; all bad. Thank goodness she's okay at making computers do things. Currently she is a software engineer at Carousell, contributing to the web platform. Before that in her career, she has taken on multiple roles - iOS engineer, backend engineer and fleetingly a product designer. Her current favourite function is .split().

Web Components and the AOM

Léonie Watson @LeonieWatson

We can use Web Components to create reusable solutions. With Custom Elements, the Shadow DOM, HTML Templates, the Web Speech API, and a little ARIA, we can create a progressively more advanced solution for anyone who wants to listen to content; and when the Accessibility Object Model (AOM) lands, we'll be able to do even more.

Léonie is Director of TetraLogical; a member of the W3C Advisory Board; co-Chair of the W3C Web Platform Working Group; and a member of the Accelerated Mobile Pages (AMP) Advisory Committee. Amongst other things, Léonie is co-organiser of the Inclusive Design 24 (#id24) conference; co-author of the Inclusive Design Principles; and mentor to young people interested in the fields of accessibility and inclusive design.

Variable fonts and the flexible nature of screens, environments and devices

Mandy Michael @Mandy_Kerr

Variable Fonts allow typography on the web to adapt to the flexible nature of screens, environments and devices. We can use variable fonts with pre-existing technologies to improve our font performance, design, accessibility and usability of our websites.
We can start to design our typography to adjust to various inputs, situations or events which might allow us to modify our fonts to aid in storytelling, or achieve improved readability and legibility in different situations, environments or on larger or smaller screens.
Let’s begin to explore new and exciting creative opportunities for storytelling, design and expression in ways standard fonts could never provide us. This is just the beginning of our journey to discover what we can do with variable fonts.

Mandy’s passion is CSS, HTML and JS, she has a particular interest in web typography, accessibility and modern layouts, and hopes to inspire that passion in others. With the aim to create a community of web developers who can share, mentor, learn and grow together she is a co-organiser and Director of Mixin Conf, the founder and co-organiser of Perth’s front-end developer meetup Fenders and currently works as a Development Manager at Seven West Media in Western Australia.

Navigating the Wild Seas of Native ES Modules

Gil Tayar @giltayar

ES Module support in Node v12 is not just a refinement of the support it has in Node v10, but is rather pointing to a direction in which Node and browser ES Modules converge into one system, a system which will enable ES modules to "just work" within the native npm ecosystem, without the need for transpilers or bundlers. This talk will examine this, and show how this will be possible in the upcoming years.

From the olden days of DOS, Gil was, is, and always will be a software developer. He has co-founded WebCollage, survived the bubble collapses, and designed cloudy projects at Wix.
His current passion is figuring out how to test software, a passion which he has turned into his main job as Senior Architect at Applitools, where he develops tests for software that tests software, which is almost one meta layer too many for him.

The browser as a modular, networked video synthesizer

Olivia Jack @_ojack_

Most libraries and abstractions for creating graphics in Javascript are focused on 2D shapes (SVG and canvas) or simulating 3D rendering. The talk will instead explore generative graphics inspired by modular, analog video synthesizers from the 1970s, in which visuals are created by routing, transforming, and recombining multiple sources and outputs in realtime (such as cameras, videos, and application windows).
By using WebRTC to share video peer-to-peer, each browser/device can output a video stream, and receive and modify video streams from other browsers/devices. Transformations to the color, coordinates, and blending of a visual source are abstracted as separate Javascript functions which can be chained and composited to create complex visual patterns. The talk will explore technical, aesthetic, and collaborative possibilities of treating a web app as a series of interconnected and heterogeneous nodes, rather than as a specific “site” or “place”.

Olivia is an independent programmer and artist who works frequently with audiovisual installations, interactive visuals for dance performances, cartography, live-coded visuals, and experimental interfaces. She is the developer of Hydra, a browser-based platform for networked visuals that is inspired by analog modular synthesis. Originally from San Francisco, she currently lives and works in Bogotá, Colombia.

Real World Problems - Internet beyond the First World Bubble

Keerthana Krishnan @KeerthanaK17

The Internet of today originated as an experiment in the West. But as it expands to accommodate a larger user base in Asia, huge gaps are created between what the consumers want and what engineers build in a digital solution.
* How can we build websites for illiterate people?
* How can we improve the performance of our websites in spite of terrible infrastructure?
How can we come together to make the best digital experience we can for the people who have only started embracing the internet recently?
Because they will be the users of tomorrow.

Music and Art with ML

Monica Dinculescu @notwaldorf

People make things. You make things. Most of the time you make Very Serious Things™️ that help your bosses sell more shoes or saxophones or those tiny coffee packets. And that’s good, because you gotta eat and stuff. But something else has gotta eat, too: your brain. Music is creation, art is creation, code is creation. I think it’s important to goof around with code sometimes, or make things that let other people goof around with code. And sometimes, that becomes the Very Serious Thing™️. Magenta.js is one of these things; let's talk about it!

Monica works on Magenta, in Google Brain, where she makes generative music and art with Machine Learning. In the past she's worked on Polymer, web components, and Chrome, and has probably at least once broken the Internet for you. She is unreasonably excited about emoji, wary of web fonts, and will become your best friend if you bring her cheese. On second thought, she may be a mouse.

Introduction to the Component-based API

Leonardo Losoviz @losoviz

The Component-based API is a new concept of API which pushes further from GraphQL the boundaries of how much data can be retrieved in a single request, how data is organized into an effective hierarchical structure, and how fast can data be retrieved from the DB. We will learn what this new API looks like, how to use it, and how our application can become more modular through it.

Leonardo Losoviz is an independent open source developer, creator of a framework for building modular websites called PoP. The only non-musician in his family, this doesn't bother him, because coding is also making art. He lives in a loop: he dreams of code and, when he wakes up, he codes his dreams.

Getting Closure on Hooks

Shawn Wang @swyx

The design of React Hooks requires a good understanding of closures in JavaScript. In this talk, we’ll reintroduce closures by building a tiny clone of React! This will serve two purposes – to demonstrate the effective use of closures, and to show how you can build a Hooks clone in just 29 lines of readable JS. Finally, we arrive at how you get Custom Hooks and the Rules of Hooks out of this incredible mental model!

Build next gen web apps using web components

Sumit Chaudhari @sumit_nitsurat

In today`s world the front end technology is evolving really fast. New frameworks are getting launched to simplify the developers life. But with the changing technology it`s really hard to move from one framework to another or update to the newest version.
Web components is a relatively new standard enabling front end developers to create cross frameworks compatible components. it lets you write reusable components with native browser Api with zero external dependencies.
In this workshop we will learn to build a web app with reusable components using web components (custom elements, Shadow DOM, Html templates, Modules). We will also get acquainted with helper library lit-element and how we can integrate these components with existing frameworks.

Prior knowledge of HTML, JavaScript and CSS required in order to follow along.
Please bring a laptop, preferably with NodeJS and administrator permissions to install new software. Don’t forget your favourite IDE for JavaScript development.

Seeking the Balance in Framework Design

Evan You @youyuxi

As the author of Vue, I often get asked on how the major JavaScript frameworks today differ from one another. Typically people expect technical details: size, performance, ecosystem... but to me, what fundamentally differentiates frameworks from one another is where a framework lands on the primitives vs. conventions spectrum. This is usually a conscious design decision, and the major frameworks we see today manifests three different segments of this spectrum. In this talk I'll discuss how these design choices have affected the adoption and growth of these frameworks, and why there might not be one single optimal balance point.

Evan is an independent open source developer. He created Vue.js, a popular frontend framework and now works on it full-time. Before going full-time open source, Evan worked as a core dev at Meteor, and before that as a creative technologist at Google Creative Lab.

The Future of JavaScript and AI

Asim Hussain @jawache

There are many exciting things happening with AI, from which, until recently, JavaScript developers were largely shut out.
But things are changing, if you can do npm install @tensorflow/tfjs or make an API call, you can now do AI.
In this fast-paced talk, I'll open your mind to what's possible by demoing several AI-powered JavaScript apps and show you how they were built using either TensorFlow.js or easy to use AI powered APIs.
You don't need a PhD in Maths, you don't need years of experience, you just need imagination and the willingness to try.

Double the Beyoncé: Navigating Numbers in JavaScript

Meggan Turner @megganeturner

Do you lie awake at night wondering why you can’t count up past 9 quadrillion in JavaScript? Have you ever been troubled by numbers that don’t add up correctly or do what you expect (looking at you, 0.1 + 0.2)?
JavaScript’s numbers can behave a little… unexpectedly at times, and cause bugs that can have you scratching your head for hours on end. From incorrect arithmetic to Beyoncé showing up on your page twice as often as you expect, in this talk we’ll take a look at the quirks that come from numbers in JavaScript & the strange issues they can cause.

Meggan is a Software Engineer at Jaxsta, a music startup dedicated to providing credit where credit is due. At Jaxsta, she writes code for the front-end platform, tinkers with databases & derails conversations with random music trivia (mostly about Beyoncé). When she's not coding you can find her rock climbing, swimming with sharks, or doing something else that makes her parents nervous.

The *other* spec: Internationalization in JavaScript

Ujjwal Sharma @ryzokuken

No matter what kind of developer you are, in 2019, Internationalization is honestly kind of a big deal. Especially if you're building interfaces that transcend linguistic and cultural boundaries.
Over the years, the community has developed a set of tools for solving the problems in this area but they are non-standard, hard to keep a track of and in the best case, pretty huge.
I will talk about the new Internationalization APIs in JavaScript, which solve these problems and give you a decent set of tools to build apps that work across different languages, currencies and cultures.

Ujjwal is a Node.js core collaborator, Electron maintainer, Google Summer of Code mentor and ex-student. An international speaker and a JavaScript/C++ developer, he has been working with the V8 team and the TC39 committee to help make JavaScript better, one commit at a time. He loves to talk about open source software, DevOps, JavaScript, Web Standards and the Open Web.

The different transformation stages of AOT compilers

Eytan Manor @eytan_manor

Have you ever noticed the recent trend where no one uses ES5 anymore? AOT compilers became a trivial thing nowadays; everyone uses it but very few really understand how they work. With the knowledge that I'm gonna give you in my talk, a new exciting world of possibilities will open up for you; you will understand how popular compilers such as TypeScript and Babel work behind the scenes and you be able to build cool Babel plugins. With this knowledge you will be able to not only implement things which aren't possible to do during runtime, such as ng-anotate, but you will also be able to save some precious processing power and make your apps more efficient.

Eytan is a JavaScript artist who codes for fun. Originally comes from the land of the Promise(), but has been traveling the world to discover its deepest secrets. Despite NPM goodies being his favorite treat, he consumes vanilla JavaScript the most, because less is more. His hobbies are eating, sleeping; and open-source... He loves open-source.

Web Assembly: Expectation vs. Reality

Patrick Walther

Web Assembly has arrived in all major browsers. With it being in plain sight instead of hidden behind browser flags we can start and bring our high performance applications to the browser. In this workshop we’re going to look at the basics of Web Assembly and see what is already in the browsers today and what is yet to come. From there we will implement a real performance heavy task in our browser. We will compare the performance of our Web Assembly code to a plain JavaScript version. Afterwards you will be able to decide when to use Web Assembly and what specific performance benefits It will give you.

Bring a laptop. Have a recent web-browser, Git and NodeJS installed. If local wifi allows it we will be working with http-server package locally and access this from our smartphones. If not we might use a service like Zeit Cloud (https://zeit.co/now).

Patrick started his programming journey as a Java Developer but became hooked on Web Development very quickly. At Zühlke he has been able to quickly gain a lot of expertise in various projects and industries transforming portals, platforms, calculators and many more applications into proper responsive web applications. His love for the web has grown through the years only surpassed by his love for burgers! So if you know the best burger place in Singapore, hit him up!

Steer a Satellite Groundstation Antenna in JS

Roland Turner @rolandturner

This workshop will deal at a high-level with predicting where a particular satellite will be from moment to moment (orbital mechanics), and then with real-time steering of an antenna and Doppler-correction of a radio's tuning.
Weather permitting, we'll then go outside and do it for real with a couple of amateur satellites!

Bring a laptop. Have a recent web-browser, Git and NodeJS installed.

Building a voice enabled website using the WebSpeech API

Alex Lakatos @lakatos88

Everybody is droning on about chat bots these days. But what happens if you break out the bot outside the chat window, give it voice and put it on your entire website? Make is a bit snarky, a bit helpful and a lot funny, and it ends up being entertaining and useful at the same time.
We'll go through everything you need to start building voice enabled websites using the WebSpeechAPI

Bring a laptop. Have Node.js and Chrome installed. Preferably bring headphones to keep the room quiet.

Alex Lakatos is a JavaScript Developer Advocate for Nexmo and a Mozilla Tech Speaker as well as a contributor to the Mozilla project for the past six years.

Web Assembly: The future of JS and a multi-language web

Kas Perch @nodebotanist

80% of users are running browsers capable of running languages other than JS in their browser. It's a new change, but an important one; we're looking at a future where the web will be built not just on JS, but on C, Rust, even GoLang. Let's talk about WebAssembly; why it came about, what it's good at, and why it really doesn't spell doom for JS but instead allows you to truly enhance web experiences by augmenting JS with the ability to use modules written in other languages that can perform tasks faster or more efficiently. We'll go over what WebAssembly is, how to build a WebAssembly module, and why this may be a force that will shape not only how we think about JS, but the entire web experience.

Kas (they/their/them) is a Developer Advocate at Cloudflare by day, and a Twitch Code/Hardware streamer, IoT author, and gamer by night. They love talking about serverless architecture, Web Assembly, IoT and its implications, and a myriad of other topics. They'll also totally show you a million pics of their 2 cats if you let them.
