This Week In React 107: Plasmo, Panapasi, Fastify-DX, Remix, Solid, useInsertionEffect, JSI, Vite, Angular, Safari...

Hi everyone!

Remix, TanStack, Chakra, Mitosis, Panapasi, Fastify-DX... What do they have in common?

They are becoming framework-agnostic! It's clearly a growing trend!

I arrived in Krakow for the App.js conf. Hope you bring back some great React-Native content for next week

React

Plasmo - Like Next.js for browser extensions!

A new framework focused on the creation of browser extensions, based on React and TypeScript. Open-source, free core, which offers paid CI/CD cloud service.

Panapasi - The Universal UI Library

We see more and more UI libs that want to offer a native cross-framework support (see Chakra, TanStack libs...). Panapasi is to my knowledge the first project of its kind based onMitosis, compiling a JSX Lite dialect to the target frameworks.

Fastify DX for React

New fullstack framework under development, based on Fastify and Vite. Agnostic: can be adapted to several frameworks (React, Vue, Solid...). The React integration aims to be a lightweight alternative to Next.js and Remix, based on React-Router and Valtio.

Converting a React Component to SolidJS

Converting a pagination component from React to Solid. A lot of JSX code can be taken as is, but the hooks will have to be adapted a little. Solid represents a real innovation: the code looks a lot like React in the end (without dependency array ) but the execution model is reactive.

Redux Toolkit's new listener middleware vs. Redux-Saga

Nice side by side comparison of the new RTK Listener system vs Redux Saga. Compares the implementation of many use-cases. RTK Listener seems like a good lightweight alternative to Redux-Saga, with a relatively low learning curve. A good resource to choose one or the other, or to plan a migration.

React 18 useEffect Double Call for APIs: Emergency Fix

Jack gives 6 possible solutions to avoid the double query problem with React 18's StrictMode. Using a lib like React-Query or RTK-Query (hmmm, TanStack Query ) seems the easiest.

Extras:

• Second draft of the useEffect guide: new beta doc
• Remix-ing Routing in Angular: Remix is framework-agnostic. Brandon shows how it can be integrated with the brand new Angular v14.
• Setting up a dev environment with React, Vite, and Tailwind: highlights the advantages of Vite over Webpack/CRA.
• Know about the useInsertionEffect hook in React 18: presentation of a hook intended for authors of CSS-in-JS libs. Allows styles to be inserted at the best time.
• Modulz has been acquired by WorkOS: gives details on the maintenance of their popular React libs Radix and Stitches.
• The Case For Prisma In The Jamstack: explains the interest of combining Prisma with various frameworks like Next.js or Redwood.
• React Server Components + SSG/ISR: it will be possible to use Server Components with static generation: the SSG framework will output static.rscfiles.
• useRef + TypeScript contravariance: my analysis + 2 suggested solutions.
• CSS @scope + React: upcoming CSS feature that could be useful for the React component model and encapsulation
• TanStack: TanStack libs are gradually becoming framework-agnostic! TanStack Query, TanStack Virtual, TanStack Table...
• Remix-Flat-Routes: package to support a flat file-system routing convention for Remix. Gives good arguments for using it.
• Jest-Image-Snapshot: visual regression testing tool. New v5 upgrades to Jest 28. Best used withStorybook StoryShots.
• Recoil Relay 0.1.0
• Redwood in 100 Seconds

React Native JSI/TurboModules pitfalls
