Understanding the New Event Loop in React Native

Top Content

Mo Khazali

Theodo

I'm going over the new event loop in React Native, which is one of the more interesting parts of the new architecture. The new architecture includes the JSI for synchronous communication between layers, new Native modules for type safety and code sharing, and the Fabric renderer for prioritized rendering and support for modern React 18 features. The React Native event loop works differently from the previous architecture, executing tasks and updating rendering. The React Native team can now schedule JavaScript code within React components to execute at specific times, allowing for control over the execution schedule. React Native can now prioritize rendering urgent events, resulting in a more synchronized and flicker-free UI. The goal of the new event loop specification is to align React Native more closely with the web, providing capabilities and behaviors similar to the web. Migrating to the new React Native architecture aims to minimize fundamental changes for existing codebases and ensure proper support from library maintainers.

Tony Alicea

Tony is a bestselling Udemy and Pluralsight author, known for his online courses such as "JavaScript: Understanding the Weird Parts"

In this talk, the speaker aims to build an accurate understanding of how the new React compiler works, focusing on minimizing re-renders and improving performance. They discuss the concept of memoization and how it can be used to optimize React applications by storing the results of function calls. The React compiler automates this process by analyzing code, checking dependencies, and transpiling JSX. The speaker emphasizes the importance of being aware of memory concerns when using memoization and explains how the React compiler detects changes in function closure values. They also mention the Fibre Tree, which drives the reconciliation process and helps optimize performance in React. Additionally, the speaker touches on JSX transpilation, compiler caching, and the generation of code. They encourage developers to understand the code generated by the compiler to optimize specific sections as needed.

Robin Marx

Akamai Technologies

HTTP 3, also known as H3, is the latest version of the HTTP protocol with new performance-related features. Enabling HTTP 3 requires minimal effort and provides significant benefits, but limits fine-grained control over performance features. Zero RTT has limitations due to security reasons and restrictions on allowed requests. Resource loading and prioritization in HTTP 3 have some problems, as browsers may not agree on resource importance. Fetch priority allows fine-grained control over resource loading order, and resource discovery can be improved with 103 Early Hints. Web transport provides low-level access to QUIC and HTTP3 features for real-time use cases.

React Query is not a data fetching library, but an Asian state manager. It helps keep data up to date and manage agent life cycles efficiently. React Query provides fine-grained subscriptions and allows for adjusting stale time to control data fetching behavior. Defining stale time and managing dependencies are important aspects of working with React Query. Using the URL as a state manager and Zustand for managing filters in React Query can be powerful.
