#user interfaces

User interfaces (UI) are the means by which users interact with a computer program or application. UI is typically composed of graphical elements such as windows, menus, buttons, and text boxes, which allow users to input data, view output, and control the behavior of the program. In the context of JavaScript, user interfaces can be created using HTML, CSS, and JavaScript, allowing developers to create interactive webpages and applications that respond to user input.

The Need for Speed: How AWS New JS Runtime is Redefining Serverless Latency
In today’s world of modern applications, swift responsiveness is essential. Users expect seamless interactions where every action triggers an immediate response.Serverless services such as AWS Lambda, allows developers to build modern applications without the need to manage traditional servers or infrastructure. However, Serverless services might introduce additional latency when new execution environments are provisioned and due to (by design) having less resources than traditional servers or containerized environments.To mitigate this problem, AWS have developed an experimental JavaScript runtime, called LLRT, built from the ground up for a Serverless environment. LLRT (Low Latency Runtime) is a lightweight JavaScript runtime designed to address the growing demand for fast and efficient Serverless applications. LLRT offers more than 10x faster startup and up to 2x overall lower cost compared to other JavaScript runtimes running on AWS Lambda.In this session you will discover how it's different from what's already out there, see its performance in action and learn how to apply it to your Serverless functions.

Zen and the Art of UI Components Testing
Yes, we do need to test our UI components but... If this rings a bell, and especially if your application has advanced UI functionality, this talk is for you.In this talk, we will cover what are the factors that need to be tested in UI components. We will challenge the testing pyramid when it comes to UI Components testing, and review the different tools that we have nowadays for making UI component testing complete Zen.

Game Development with ReactJS, CSS, and React Three Fiber
In this talk, I will share my experience in game development using ReactJS/CSS. We will explore how to make the most out of the component management provided by this library, along with the capabilities of CSS for creating an appealing user interface. Additionally, we will uncover how to leverage the React Three Fiber library to create games with a 3D experience.

Ensuring your Users are on the Right Path: the Future of Modals and Focus Management
With *dialog* and the inert attribute landing in all major browsers in 2022, we as web developers now have simple yet powerful primitives to help build complex app-like flows on the web, rather than the over-engineered or leaky solutions we've relied on for years. Let's demystify these primitives and talk through how they make your code simpler: from plain HTML, Web Components, to React/similar.

Test your UI in the REAL Browser
Imagine writing a complex function without unit tests. You would have to verify every scenario manually, over and over again. Cumbersome, but that's how most teams build user interfaces.
Imagine if you could build UIs and test UIs in the same place. If your components included expectations for how they were supposed to behave, you'd know the instant they broke.Storybook provides an organized approach to building UIs. You document a component's use-cases as stories, which are then rendered in isolation. Stories are like tests, but for UI. Storybook interaction testing allows you to script interactions and check expectations in the story itself. That allows you to run and debug UI tests in the same environment UI components are developed for: your browser.

Why Paid UI Components Aren’t Evil
In this talk I’m going to convince you that paid UI components will solve all your problems, and that you should immediately give me all of your money. Maybe. Or perhaps I’ll draw on my experience working both on free and open source tools (jQuery, jQuery UI, NativeScript), as well as paid tools (Kendo UI, KendoReact), and discuss which type of tool makes sense depending on your team and needs. In any case the talk will go fast because lightning is in the title.

Building a Custom Component Library – Fast
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.
