Composites - One of the most exciting JS proposal

Will be discussed this week at TC39, aiming to progress to stage 2

If this lands, don't underestimate the impact it will have.

Your backend payloads can become composite,
-> stable "auto memoized" obj

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

One of the most exciting JS proposals now has a draft spec

Aiming for stage 2 at the next TC39 meeting

Screenmap - useful tool for your mobile / RN / Expo CI

It's quite nice to be able to see how your code changes impact mobile screens in every PR

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

👀 Promising tool for your mobile dev harness

- Screenshot mobile screens
- Generate a screen map, post it to a PR
- Browse changed/added/removed screens conveniently

I've been using something similar on websites for years based on sitemap.xml, and it caught so many mistakes.

[This Week In React @ThisWeekInReact]

Are you using Google Maps 3D yet? 👀

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

👀 React Google Maps 1.10

Completed its existing Google Maps 3D support with declarative components

GLB models, HTML markers, polylines, polygons, terrain flattening, and circular paths

The balloon is a 3D marker - animated GLB model

[This Week In React @ThisWeekInReact]

Motion shipped an improved React <ViewTransition> wrapper

[Motion @motiondotdev]

Motion 13.4 introduces <AnimateView />

A lightweight view transitions component built on React's new ViewTransition API. Adds spring support, dynamic targets, animation controls, and a simple props API - no more wrangling pseudo selectors!

[This Week In React @ThisWeekInReact]

React v19.3 will be in React Native 0.88

What does it mean for RN devs, in practice?

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

👀 React Native 0.88 + React 19.3 🎉

The React version upgrade was recently merged into main

The 0.88 branch is already cut, RC.0 already released

The commit was cherry-picked so it should still be included 👍

Exciting release!

Just in time for our next email!

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

🚨 React v19.3 is out!

TLDR:
- <ViewTransition> → stable
- Fragment Refs → stable
- use(browser()) to opt out of SSR
- RSCs can render <Context>, no <Provider> wrapper needed
- Trusted Types support, useful alongside CSP to prevent XSS

Another step toward React Native 1.0?

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

React Native 1.0 is still on the horizon

0.87 shipped Strict TypeScript API by default

Now it seems the team is working toward a stricter C++ public API

Many C++ API headers are getting a 3-tier guard system to prevent misuse

For now, will be opt-in with RN_STRICT_API

[This Week In React @ThisWeekInReact]
