FAQ

Vitor Norton is a Brazilian developer advocate at SuperViz and a 10-time Microsoft MVP, passionate about connecting people and remote work.

Collaborative components are tools that enhance real-time collaboration and connectivity among users, such as mouse pointers sync, online status indicators, and real-time updates in applications like Gather Town and Miro.

The mouse pointer feature works by synchronizing the position of users' cursors in real-time using a combination of React components, event listeners, and WebSockets for fast, bidirectional communication.

The PubSub pattern, or publish-subscribe pattern, is a design pattern where messages are sent (published) and received (subscribed) by parties in a system, facilitating asynchronous and decoupled communication.

WebSockets enable continuous two-way communication between clients and servers, allowing real-time updates with low latency and persistent connections, ideal for chat and live updates.

CRDT, or Conflict-Free Data Types, is a data structure that allows synchronization of data across devices without conflicts, crucial for building reliable real-time collaborative applications.

Examples include Gather Town for a game-like interactive workspace, Miro for collaborative whiteboarding, Figma for design collaboration, and Microsoft Teams for meeting coordination.

Vitor Norton values remote work because it allows him to work from anywhere in the world, aligning with his passion for connecting people and utilizing productivity tools.

Adrien Baron

Maker of clashofstats.com, Vue GWT and Tiny Frontend

This talk discusses the usage of Microfrontends in Remix and introduces the Tiny Frontend library. Kazoo, a used car buying platform, follows a domain-driven design approach and encountered issues with granular slicing. Tiny Frontend aims to solve the slicing problem and promotes type safety and compatibility of shared dependencies. The speaker demonstrates how Tiny Frontend works with server-side rendering and how Remix can consume and update components without redeploying the app. The talk also explores the usage of micro frontends and the future support for Webpack Module Federation in Remix.

Routing in React 18 and Beyond

Top Content

Delba de Oliveira

Senior Developer Advocate @ Vercel

Routing in React 18 brings a native app-like user experience and allows applications to transition between different environments. React Router and Next.js have different approaches to routing, with React Router using component-based routing and Next.js using file system-based routing. React server components provide the primitives to address the disadvantages of multipage applications while maintaining the same user experience. Improving navigation and routing in React involves including loading UI, pre-rendering parts of the screen, and using server components for more performant experiences. Next.js and Remix are moving towards a converging solution by combining component-based routing with file system routing.

The Talk discusses the balance between flexibility and consistency in design systems. It explores the API design of the ActionList component and the customization options it offers. The use of component-based APIs and composability is emphasized for flexibility and customization. The Talk also touches on the ActionMenu component and the concept of building for people. The Q&A session covers topics such as component inclusion in design systems, API complexity, and the decision between creating a custom design system or using a component library.

Understanding React’s Fiber Architecture

Top Content

Tejas Kumar

Author of the "Fluent React" bestselling book, software engineer with 23 years of experience, and host of the developer-loved ConTejas Code podcast.

This Talk explores React's internal jargon, specifically fiber, which is an internal unit of work for rendering and committing. Fibers facilitate efficient updates to elements and play a crucial role in the reconciliation process. The work loop, complete work, and commit phase are essential steps in the rendering process. Understanding React's internals can help with optimizing code and pull request reviews. React 18 introduces the work loop sync and async functions for concurrent features and prioritization. Fiber brings benefits like async rendering and the ability to discard work-in-progress trees, improving user experience.

The Eternal Sunshine of the Zero Build Pipeline

m4dz

DX Engineer at alwaysdata

For many years, we have migrated all our devtools to Node.js for the sake of simplicity: a common language (JS/TS), a large ecosystem (NPM), and a powerful engine. In the meantime, we moved a lot of computation tasks to the client-side thanks to PWA and JavaScript Hegemony.
So we made Webapps for years, developing with awesome reactive frameworks and bundling a lot of dependencies. We progressively moved from our simplicity to complex apps toolchains. We've become the new Java-like ecosystem. It sucks.
It's 2021, we've got a lot of new technologies to sustain our Users eXperience. It's time to have a break and rethink our tools rather than going faster and faster in the same direction. It's time to redesign the Developer eXperience. It's time for a bundle-free dev environment. It's time to embrace a new frontend building philosophy, still with our lovely JavaScript.
Introducing Snowpack, Vite, Astro, and other Bare Modules tools concepts!

Next.js is a compelling framework that makes many tasks effortless by providing many out-of-the-box solutions. But as soon as our app needs to scale, it is essential to maintain high performance without compromising maintenance and server costs. In this workshop, we will see how to analyze Next.js performances, resources usage, how to scale it, and how to make the right decisions while writing the application architecture.

Best Practices and Patterns for Managing API Requests and States

Workshop

Thomas Findlay

With the rise of frameworks, such as React, Vue or Angular, the way websites are built changed over the years. Modern applications can be very dynamic and perform multiple API requests to populate a website with fresh content or submit new data to a server. However, this paradigm shift introduced new problems developers need to deal with. When an API request is pending, succeeds, or fails, a user should be presented with meaningful feedback. Other problems can comprise API data caching or syncing the client state with the server. All of these problems require solutions that need to be coded, but these can quickly get out of hand and result in a codebase that is hard to extend and maintain. In this workshop, we will cover how to handle API requests, API states and request cancellation by implementing an API Layer and combining it with React-Query.
Prerequisites: To make the most out of this workshop, you should be familiar with React and Hooks, such as useState, useEffect, etc. If you would like to code along, make sure you have Git, a code editor, Node, and npm installed on your machine.

Rapid UI Development in React: Harnessing Custom Component Libraries & Design Systems

Workshop

Richard Moss

In this workshop, we'll take a tour through the most effective approaches to building out scalable UI components that enhance developer productivity and happiness :-) This will involve a mix of hands-on exercises and presentations, covering the more advanced aspects of the popular styled-components library, including theming and implementing styled-system utilities via style props for rapid UI development, and culminating in how you can build up your own scalable custom component library.
We will focus on both the ideal scenario---where you work on a greenfield project---along with tactics to incrementally adopt a design system and modern approaches to styling in an existing legacy codebase with some tech debt (often the case!). By the end of the workshop, you should feel that you have an understanding of the tradeoffs between different approaches and feel confident to start implementing the options available to move towards using a design system based component library in the codebase you work on.
Prerequisites: - Familiarity with and experience working on large react codebases- A good understanding of common approaches to styling in React
