A Recap of React Conf 2025 — An official roundup of the year’s largest official React event that took place earlier this month, covering areas like new React 19.2 features, React Compiler 1.0, big changes to React Native, and links to the most essential talks at the event.

💡 The Remix folks have a similar roundup of Remix Jam which took place the week after React Conf and where Remix 3 was first unveiled.

Directives and the Platform Boundary — First there was the "use strict" directive to opt in to strict mode in JavaScript, but now you’ll encounter use client, use server, use no memo, and more, despite not being standard JS features at all. Tanner thinks this proliferation of directives comes at a cost and a risk of framework and tooling lock-in.
Tanner Linsley (TanStack)
IN BRIEF:
-
🤔
use no memois a new React directive to prevent a function from being optimized by React Compiler. -
📱 Loren Stewart built the same app ten different times to compare the performance differences between approaches (including two React-based ones) on mobile devices in particular.
-
On X, Tzvetan Milkov showed off an interesting proof of concept of React driving the Dear ImGui GUI library with the Hermes JS engine as an alternative way to create native apps.
How to Fix Any Bug — Dan Abramov ran into a bug when working with React Router and AI failed to solve it. Why? It didn’t have a good ‘repro’ to work with – that is, a set of instructions and the simplest code needed to reproduce the bug. Dan explains the importance of such repros when finding bugs and what his bug ultimately turned out to be.
