The biggest JS conference in the cloud

Vite is a new build tool that intends to provide a leaner, faster, and more friction-less workflow for building modern web apps. This talk will dive into the project's background, rationale, technical details and design decisions: what problem does it solve, what makes it fast, and how does it fit into the JS tooling landscape.

Neurotechnology is the use of technological tools to understand more about the brain and enable a direct connection with the nervous system. Research in this space is not new, however, its accessibility to JavaScript developers is.
Over the past few years, brain sensors have become available to the public, with tooling that makes it possible for web developers to experiment building brain-controlled interfaces.
As this technology is evolving and unlocking new opportunities, let's look into one of the latest devices available, how it works, the possibilities it opens up, and how to get started building your first mind-controlled app using JavaScript.

JavaScript in the browser runs many times faster than it did two decades ago. And that happened because the browser vendors spent that time working on intensive performance optimizations in their JavaScript engines.
Because of this optimization work, JavaScript is now running in many places besides the browser. But there are still some environments where the JS engines can’t apply those optimizations in the right way to make things fast.
We’re working to solve this, beginning a whole new wave of JavaScript optimization work. We’re improving JavaScript performance for entirely different environments, where different rules apply. And this is possible because of WebAssembly. In this talk, I'll explain how this all works and what's coming next.

A look into Pixi.js coolest and lesser known features.

If your company is anything like the ones I’ve worked for, you have apps with seven different button designs, three different datepickers, and a bizarre collection of dropdowns that may or may not be accessible. A growing trend to deal with this inconsistency is to build a custom design system or component library. Essentially, you build The One Way™ to create a datepicker for your organization, and ask that the rest of your company to conform to your new system. But building a component library comes with a lot of challenges, like, which frameworks or libraries should you use (if any)? How do you make sure your components are accessible? And how to you distribute your components so your whole company can use them? In this lightning talk you’ll learn how to build a component library fast building on top of a library like Kendo UI. You’ll learn tips
&
tricks on how to get up and running, how to customize components, and how to distribute components throughout your organization.

Developers want to ship and create value for our users. Why, then, do so many teams struggle with getting things to production quickly? In this talk, Jason Lengstorf will look at the impact our frontend architecture and infrastructure has on our teams’ ability to build, iterate, and deploy software — and how it affects the quality and risks of deployment.

Learn how NodeSource strengthens their competitive advantage building their product on InfluxDB to increased visibility into production applications and presents better security monitoring and alerts into their solution.

Retool is a front-end as a service tool that is similar to React and can be 10x faster than coding a web app from scratch. We’ll focus on how and why it is used for internal tools at some of the fastest growing companies and take a minute to walk through how it works, where it’s a good fit and where it’s not.

With so many libraries to choose from for state management, why not add one more? The ECMAScript Proxy API enables you to intercept and redefine how an object operates. Let's explore how you might use the Proxy API for state management!

Learn about state modeling with state machines and statecharts can improve the way you develop application logic, and get a sneak peek of never-before-seen upcoming visual tools that will take state management to the next level.

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.

Wait! Not so fast - Stop scrolling and hang out with me for a while! When done right, scroll based animations can add polish to a site, and make online storytelling feel more immersive. GreenSock's ScrollTrigger enables you to achieve buttery smooth scroll based animations with minimal code. Let's dig in to some of it's features together.

Blitz.js is the Fullstack React Framework. It's heavily inspired Ru on Rails and is focused on making you as productive as possible. It's built on Next.js and adds all the missing pieces you need for building a fullstack app with a database. By far the biggest innovation of Blitz is the new "Zero-API" data layer that abstracts away the API so you don't have to mess with REST or GraphQL APIs! Brandon will cover all the important parts, so you'll know if you might want to use Blitz or not.

In this lighting talk Fabrizio will go through the main highlights of CommerceLayer, comparing the headless approach to the traditional "monolithic" ecommerce platforms. We will speak about security, performances and scalability.

Does hearing about potential new features of Javascript makes you excited? Then this talk is for you! We will walk through a few interesting proposals from TC39 from stage-0 to stage-3. Let us see how beneficial these proposals are with code samples and some live coding.

My favorite things in life are cats, computers and crappy ideas, so I decided to combine all three and make an IoT (Internet of Things) litter box using a Raspberry Pi and JavaScript! If you have ever wanted to get build your own IoT project, but didn’t know how to start, then this is the talk for you.
Together, we will go through how I setup my IoT Litter Box from start to finish. Including how to setup Node.js on a Raspberry Pi and how to connect sensors to a Raspberry Pi and how to read the sensor inputs with Node.js.

Synchronizing multiple streams, particularly multiple live streams, and especially when the audio is critical too, can be incredibly difficult. How, then, could you build an experience where you have a few camera angles and you want a viewer to be able to seamlessly pick one? We'll walk through a hack technique that allows you to do just that without ever having to worry about synchronization.

Almost every developer thinks that adding one more log line would not decrease the performance of their server... until logging becomes the biggest bottleneck for their systems! We created one of the fastest JSON loggers for Node.js: pino. One of our key decisions was to remove all "transport" to another process (or infrastructure): it reduced both CPU and memory consumption, removing any bottleneck from logging. However, this created friction and lowered the developer experience of using Pino and in-process transports is the most asked feature our user.
In the upcoming version 7, we will solve this problem and increase throughput at the same time: we are introducing pino.transport() to start a worker thread that you can use to transfer your logs safely to other destinations, without sacrificing neither performance nor the developer experience.

In this talk we will explore the great benefits of breaking a big modern app to meaningful, independent pieces – each can be built, deployed and loaded separately. We will discuss best practices and gotchas when trying to apply this microservice-like pattern to the chaotic world of the browser, and we'll see how building the right pieces guarantees a brighter future for your apps. Let's dive into Neverendering story of modern front-end architecture.

How long have we been watching movies about reality and how exciting it looks! You may not have noticed, but virtual reality is already in our lives, even in our browsers. There are more and more ways to apply these technologies. Let's take a look at VR and AR and see how they look in real life.

Seasoned and beginner alike, developers have a habit of jumping right into a framework or new technology that makes a lot of promises while also glazing over important fundamentals that without, tend to hold back a website or application’s potential. Without some basic knowledge of HTML, you might inadvertently exclude people from learning about your company through your website due to poor accessibility. Lacking an understanding or simply being afraid of CSS, you might be more prone to add unnecessary libraries on top of libraries that just add to the weight of the page, impacting how quickly your app can load. In this talk, we’ll go over some basic HTML and CSS strategies that can immediately be used right alongside of JavaScript including frameworks like React and Vue that will provide another range of benefits like better accessibility, simpler code, and ways you can improve SEO letting search engines like Google more easily figure out what your page is about.
