Using front-end features can be challenging. Model federation is an approach to implement micro frontends. Micro frontends can be built-in or use runtimes. Two micro frontends need to update together to ensure consistency. Other techniques for micro frontends include web components, system.js, iframes, and monorepos. Model federation in Webpack 5 decouples runtime from build tools, allowing flexibility in model loading. High availability and error boundaries are important for Model Federation. Full-federated sites enable fast development cycles and easy testing. Importing components from a federated model requires dynamic imports, dependency sharing, and performance considerations. Debugging tools like Medusa and the Model Federation plugin for Chrome help identify and resolve issues. Consistent styling can be achieved by using the same UI kit. Routing can be handled by a shell application or frameworks like Single SPA. Decoupling components using specific federated models and considering tradeoffs when designing application growth strategies. Determine if Microfrontends are necessary based on the need for independent modular components in a growing product.

Building a component library involves making various decisions such as using a JavaScript framework, considering accessibility in testing, and using a monorepo. Building a component library allows for faster interface creation and consistent visual language. Making the wrong choice can lead to owning the complexity of interactions. Offloading the complexity to an open-source library can be beneficial. Exporting as a single package or scoped packages have their advantages and disadvantages. Setting up a specific workflow and repo structure is important for publishing components. It is recommended to publish as ESM and avoid bundling the library. Leveraging browser capabilities and using fundamental tools like CSS and TypeScript can be beneficial.

Let's start diving into the presentation on AI and accessibility. AI is a simulation of human intelligence by machines, and this presentation will focus on narrow AI. Generative AI has achieved great things in accessibility, and AI advancements have improved various applications for people with disabilities. OpenAI's newest model allows blind people to access AI through Be My Eyes. Challenges with AI include bias and accuracy. AI can be a useful tool in improving accessibility, but it has limitations and risks. Advocating for AI ethics and accessibility, collecting data, and addressing specific accessibility concerns are important. Khan Academy is working on improving accessibility in education.

In this talk, the speaker explores how auto-complete can be implemented in different ways across various frameworks and libraries such as React, Vue, Angular, preact, Svelte, solid, and HTMX. The speaker discusses the different approaches to handling state and updating it in each framework. They also cover topics like debouncing user input, making API calls, and list rendering. The talk concludes with considerations for choosing a front-end framework and the speaker's personal preference for Svelte and Vue. They also mention the benefits of using web components to reduce boilerplate code. Overall, the talk aims to showcase alternative ways of developing applications beyond just React and encourage developers to explore and experiment with different frameworks.

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.
