Preact VS react-18

> React is a small rendering library

Sorry, can't agree. React is a state management library that also attaches efficient rendering on top of the DOM diff it computes as it propagates the state changes.

This allows React apps to remain so simple (one function per component) and so composable without turning into an unmanageable dish of callback / future spaghetti.

There is a number of other VDOM libraries, but what sets React apart is the data / state flow strictly in one direction. This allows to reap many of the benefits of functional programming along the way, like everything the developer sees being immutable; not a coincidence.

Regarding the size, preact [1] is mostly API-compatible, but also absurdly small (3-4 kB minified), actually smaller than HTMX (10 kB). But with preact you likely also want preact-iso, so the size grows a little bit.

Performance and user experience have become the lifeline of modern web development. Two libraries that have gained immense popularity among developers for developing interactive user interfaces are React and Preact.

For rendering the map, I went with Preact and deck.gl.

This command creates a new Vite project with React. Feel free to replace “react” with “vue” or “vanilla” if that’s more your jam. Svelte, Preact, Qwik, and others are supported, too!

Note: Astro supports a variety of popular frameworks including React, Preact, Svelte, Vue, SolidJS, AlpineJS and Lit with official integrations. While for other frameworks e.g. Angular and Qwik, you may still benefit from this tutorial and you would need to further set up the community maintained framework integrations.

In this post, we get to know more about Preact, one of this year's trending libraries. And we'll compare it to React to see which one suits better for our projects.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

Those who want to develop a library that can be used by any other reactive framework. I often see SignalLike type that tries to subtype it.

If you aren't sure why state tearing was a hot topic a few years ago, when React's concurrent mode was first discussed, this github discussion should help: https://github.com/reactwg/react-18/discussions/69.

Tanner Linsley had a great post on twitter that suggested that concurrent rendering was fundamentally at odds with fine-grained reactivity, so to better understand what he was talking about I decided to write this demo.

But it does since React 18.

See this post for more details and an example of an actual memory leak.

From the React WG:

The React working group is officially advising against using runtime CSS-in-JS.
