Serverless services like AWS Lambda allow developers to build modern applications without provisioning servers or additional infrastructure. LLRT is a low latency runtime designed specifically for serverless environments and JavaScript applications. LLRT uses a lightweight JavaScript engine called Quick.js, achieving fast execution and performance with minimal memory consumption. LLRT is ideal for latency-critical applications, high-volume functions, and integration with AWS services. It significantly improves performance, reducing cold starts and providing consistent warm start times. Users are encouraged to test LLRT and contribute to its development.

The Talk discusses the evolution of test automation from the original test automation pyramid to the testing pyramid. It explores modern approaches to UI component testing, including isolations and testing with a fake DOM. The importance of testing in a real browser and the emergence of tools like Selenium, WebDriver.io, Puppeteer, Cypress, and PlayWrite for browser automation are highlighted. The advantages of out-of-process browser automation are explained, along with the use of Storybook and Playwright for testing components. The distinction between end-to-end testing and component testing is also mentioned.

Welcome to the presentation of RightGui, an immediate mode CUI library for tools development. RightGui is a high-performance library that is stateless and uses small self-contained functions to process inputs and draw controls. It provides a variety of controls, customizable styles, and support tools for live style configuration. Additionally, there are tools like the icons editor and layout creator that allow for customizations and code generation. Reiki offers a variety of tools, including a sound editor, image manipulation canvas, and resource packer.

Jorge Rubiano, a Software Engineer from Colombia, shares puzzle, isometric, and board games developed using React.js and CSS. He demonstrates the use of WebGL and 3.js for creating 3D games on the web. ReactiveFiber, a renderer that combines React and 3.js, is showcased in movement-based and color-changing games. The Talk concludes with the development of a bowling game using ReactiveFiber and complex components.

This Talk discusses the new features of Modals and focus management in web development. The dialogue element allows for the creation of modal dialogs that appear on top of other elements and prevent interaction with elements below. The note element can mark a subtree of the DOM as inert, making it unusable. The field set component can group input elements together and disable them. Using these new primitives can improve focus control and user experience in web applications.

Storybook is a powerful tool for building UI components and testing them. It allows for easy reuse and compatibility with other tools. Storybook 6.4 introduces interactive stories and live coding, making it easier to create and debug complex components. It also integrates with popular testing libraries like Jest and Testing Library. Storybook aims to bridge the gap between end-to-end testing and unit testing, providing automated testing options for UI components.

Paid UI components are not evil and offer benefits such as guaranteed support and long-term peace of mind. They solve harder problems and provide features and guarantees that free controls may not have. Paid components also establish a direct financial relationship with the authors, eliminating the need for sponsorship or donation models.

Today, I want to talk to you about building custom component libraries fast. Every company should have its own standard set of UI controls for consistency in design, technology, and accessibility. Companies shouldn't build the harder parts of those libraries themselves, such as date pickers and data grids. But as a software developer, your time is valuable. Building custom component libraries is a better use of your time than reinventing the wheel.
