What is the potential future of React Server Components in mobile applications?

The future involves experimental and perhaps production implementations of React Server Components in mobile applications. This development could lead to faster updates, smaller application sizes, and more dynamic content delivery.

What is React Query?

React Query is a popular open-source library designed to manage server state in React applications. It provides features like caching, request deduplication, and background updates.

What is the primary focus of Alex Russell's engineering philosophy?

Alex Russell emphasizes building solutions that work well for end-users, focusing on quality and performance rather than popularity of tools or frameworks.

What role does context play in software architecture?

Context is crucial in software architecture because designing a system that aligns with business needs and organizational structure helps the system thrive.

How does the new architecture in React Native differ from the old architecture?

The new architecture replaces the asynchronous bridge with a synchronous JavaScript Interface (JSI), enabling direct communication between JavaScript and native code, reducing latency and improving performance.

Can React.js be used for mobile app development?

Yes, React.js can be used for mobile app development through React Native, which allows you to build mobile apps using React.

Why is optimizing for users at the margins important?

Optimizing for users at the margins, who often use lower-end devices, can significantly improve engagement and business outcomes, as these users make up a large part of the market.

This Talk discusses how to test mail service with Playwright, covering e-mail verification, reset password user journey, and more. It explores the use of third-party providers for reliable e-mail delivery and demonstrates how Playwright can help perform checks on e-mail content. The Talk also introduces the concept of a fake SMTP server and showcases how fixtures can be used to access the SMTP server and perform assertions on the HTML body of emails. Playwright's HTML rendering feature allows for interaction with email content as if it were a regular web page. It highlights the ability to render HTML from API calls, perform assertions on the rendered page, and exclude dynamically generated data from visual regression tests.

Micro-Frontends With React & Vite Module Federation

Top Content

Giorgio Boa

Claranet

Microfrontends is an architecture used by big companies to split monolithic frontend applications into manageable parts. Maintaining a consistent look and feel across different microfrontends is a challenge. Sharing styles can be done through Vanilla CSS, CSS modules, or CSS in JS. JavaScript variables can be used in styles, but readability and runtime overhead are considerations. Sharing state in microfrontends can be achieved through custom events, broadcast channels, shared state managers, or custom PubSub implementations. Module federation with Vite allows for client composition and sharing dependencies. Configuration is similar to Webpack, and future work includes working on the QUIC framework.

Anjana Vakil

Independent Developer Educator & Software Engineer

This Talk is about interactive data visualization in React using the Plot library. Plot is a high-level library that simplifies the process of visualizing data by providing key concepts and defaults for layout decisions. It can be integrated with React using hooks like useRef and useEffect. Plot allows for customization and supports features like sorting and adding additional marks. The Talk also discusses accessibility concerns, SSR support, and compares Plot to other libraries like D3 and Vega-Lite.

This Talk focuses on effective React state management and lessons learned over the past 10 years. Key points include separating related state, utilizing UseReducer for protecting state and updating multiple pieces of state simultaneously, avoiding unnecessary state syncing with useEffect, using abstractions like React Query or SWR for fetching data, simplifying state management with custom hooks, and leveraging refs and third-party libraries for managing state. Additional resources and services are also provided for further learning and support.

How React Compiler Performs on Real Code

Top Content

Nadia Makarevich

Coder, writer, author of Advanced React book

I'm Nadia, a developer experienced in performance, re-renders, and React. The React team released the React compiler, which eliminates the need for memoization. The compiler optimizes code by automatically memoizing components, props, and hook dependencies. It shows promise in managing changing references and improving performance. Real app testing and synthetic examples have been used to evaluate its effectiveness. The impact on initial load performance is minimal, but further investigation is needed for interactions performance. The React query library simplifies data fetching and caching. The compiler has limitations and may not catch every re-render, especially with external libraries. Enabling the compiler can improve performance but manual memorization is still necessary for optimal results. There are risks of overreliance and messy code, but the compiler can be used file by file or folder by folder with thorough testing. Practice makes incredible cats. Thank you, Nadia!

This Talk introduces React Server Components (RSC) and explores their serialization process. It compares RSC to traditional server-side rendering (SSR) and explains how RSC handles promises and integrates client components. The Talk also discusses the RSC manifest and deserialization process. The speaker then introduces the Waku framework, which supports bundling, server, routing, and SSR. The future plans for Waku include integration with client state management libraries.

Akash Hamilwasia presenting at React Summit 2025, shares React Compiler learnings and works on an AI audio platform. Memoization in React helps optimize UI performance by preventing unnecessary re-renders. React Compiler offers automatic memoization through static code analysis. React rules emphasize purity and immutability. The compiler analyzes and memoizes code changes for optimization. React Compiler package usage improves performance through code analysis. Understanding reactivity issues is crucial for handling React state. Compiler optimization requires correct dependency arrays and usage of external libraries. Measure React Compiler impact using React Profiler for optimization and real user impact analysis.
