Hi everyone!
This week it looks like we are finally entering the summer/holiday season and the pace of major React announcements is slowing down. We will also be taking a short summer break, skip 2 issues, and be back on July 17.
On the React side, we continue to have interesting content related to the Suspense drama from last week. A new React Router feature permits you to code split your route tree.
On the React Native side, it looks like the team is trying to release v0.75 as RC, and encountering some roadblocks, but it’ll probably be out soon.
The most exciting news to me is the TypeScript 5.5 stable release: it’s a great one, notably for predicate type inference! The State of JS survey results are also out if you want to explore JS trends.

The Category-Defining React Grid for Your Enterprise
Data grids are complex components of web applications, but current solutions are inefficient, require a lot of maintenance, and perform poorly. Graphite Grid transforms the landscape with two key features: retargetable rendering and reactive signal state.
Graphite Grid separates grid state from view logic, allowing a single unified state model to support a variety of render targets, declaratively or imperatively. It includes a DOM and Canvas renderer, giving developers flexible, high-performance options 🚀.
Graphite Grid is declarative and consistent, leveraging state signals to ensure seamless integration with your application. Designed with React in mind, it is the only JavaScript data grid built with React's state management primitives. Try it now!

📦 React-Router 6.24 - Lazy Route Discovery
This React Router release includes a new unstable_patchRoutesOnMiss hook that will be called when React Router can’t match any existing route. It permits you to load additional routes and implement code splitting for your routes instead of keeping them all in a single monolithic module. A welcome feature for large apps with thousands of routes, that now don’t need to load all of them upfront, delaying hydration.
Remix was supposed to take a nap, but apparently not yet! 📦 Remix 2.10 is out and already leverages that new React Router feature by exposing it through a convenient “Fog of War” feature that you can enable with a simple future.unstable_fogOfWar flag. An early discovery optimization has also been implemented to avoid waterfalls.
💸 Meilisearch — Build fast, typo-tolerant search with React
👀 React.dev PR - Add branding context menu: Right-click the website navbar logo to access the official svgs and brand colors of React.
👀 Next.js PR draft - nextConfig.requiredEnv
👀 Next.js PR draft - type check for env
🐦 Joe Savona - "Some thoughts on the suspense changes from 19 RC": To avoid situations such as past week’s Suspense drama, the React team is working on changes to get feedback earlier (working groups, RFC, canary…).
🐦 Lee Robinsin - "Here's where we're headed with caching in Next.js": “Our goal is to make all async operations (like doing a fetch) opt into dynamic rendering”, “We believe Partial Prerendering will become the default”.

📜 Component, colocation, composition: A note on the state of React: The recent Suspense drama highlights the gap between React’s component-oriented vision and its current limitations.
📜 From markdown to video - Animated code walkthroughs with Code Hike and Remotion: If you have seen recent code animation videos of Matt Pocock or Delba, here’s a great article and demos to understand how it works.
📜 Understanding React Compiler: Explains how the React compiler work, starting from the basics (transpiler, AST, memoization), then analyzing the compiler output of a concrete example.
📜 Wait for pending: A (not great) alternative Suspense algorithm: Explores the possibility of a different algorithm for Suspense, with different tradeoffs.
📜 How to make draggable Framer Motion elements snap to breakpoints: Interactive article implementation snap points on top of Framer Motion, including inertia/velocity support.
📜 Mobx Memoizes Components (You don't need React Compiler): Takes an existing demo using the React compiler and turns it into an optimized Mobx app with minimal changes. MobX prevents re-renders by auto-tracking dependencies. Note this Mobx issue explains why Mobx (based on proxies) is not compatible with the compiler, and lib creator also confirms it’s already optimized.
📜 Web Workers, Comlink, Vite and TanStack Query: React Query being an “async state manager”, it also works well to offload expensive work from the main thread.
📜 Storybook - Visual testing: The greatest trick in UI development: I agree that too many devs miss out on visual regression testing. It has a really great ROI, considering how easy it is to add to an existing Storybook. As this article shows, covering the same component with React Testing Library requires more work.
📜 Communication Between Client Components in Next.js: With RSCs, new challenges emerged to make 2 client components communicate, and you might not be able to lift the state up unless the parent is also a client component. This article proposes 3 solutions: using a Provider, search params, and server state.
📜 How to Validate Form in Remix with clientAction: Using the new Remix clientAction export can nicely complete the server action validation and progressively enhance your form with local errors.
📜 Type-safe TanStack Query with OpenAPI: Shows how to create generic React Query hooks (useGetQuery, usePostMutation...) that are fully typed according to an OpenAPI specification.
