🛠 Code, Tools & Libraries
🗓️ React DayPicker 9.9: A Component to Create Date Picker Controls — There are many date selection components out there, but few match the maturity of DayPicker which focuses on providing the basics for you to then style and customize as you wish - it complies with modern accessibility requirements too. GitHub repo.

Redux Toolkit 2.9: The ‘Batteries-Included’ Toolset for Redux — The long-standing toolset for effectively working with Redux for state management gets a performance update through a rewrite of RTK Query’s internal subscription and polling systems, automatic aborting of in-flight requests when a cache entry is removed, a new builder.addAsyncThunk method, and bug fixes.

React on Rails 15: Bringing React and Ruby on Rails Together — A long-standing framework designed to integrate React with the Ruby on Rails server-side rendering approach. v15 introduces the ability for hydration to begin before the page if fully loaded, but there’s also a (paid) React on Rails Pro variant (to be open sourced under a dual license model soon) that supports React Server Components. – GitHub repo.

A roundup of some other interesting stories in the broader JavaScript landscape, in case you’ve missed them:
-
Daniel Rosenwasser proposes that TypeScript 6.0 should have
--stricton by default. You can learn more about what’s planned for TypeScript 6.0 here. -
Nolan Lawson looks into why browsers throttle JavaScript timers.
-
Alexander Lichter and Michael Dong round up what’s new in ViteLand in the past month covering Oxlint, Vite, Vitest, Rolldown, and some forthcoming events.
-
Dan Abramov has put together an introduction to Lean for JavaScript developers. Lean is a theorem prover and language for creating formally verified code.
-
With Rspack 1.5, the fast web bundler improves barrel file optimization, has a faster file system watcher, improved browser support, and more. It’s a big release.
