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

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

Exciting release!
Just in time for our next email!
🚨 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

👀 New HTTP QUERY method
Similar to GET, with a body allowed
Safe, idempotent, cacheable
There are also headers to:
- give the query its own URI (Location) to query again without body
- give the response its own URI (Content-Location) to get the same response again
This is one of the most exciting features to look forward in React
Don't sleep on it!
👀 <React.Fragment ref>
This API is really exciting, unlocking many new composition patterns
- Already available in Canary
- OSS flag enabled, so likely coming in v19.3?
- Coming in RN too!
Recently, it has been more exhaustively documented:
