New JSX-runtime functions

This has been a long time in the making for various virtual-dom based frameworks. Historically JSX was always transpiled to createElement function calls.

// input
<div>foobar</div>

// output, we need to move "foobar" to `props.children`
createElement("div, {}, "foobar");

While this has served us well and is very reliable, it has proven to be hard to optimize. Most of the things we do in our createElement function could by done by babel directly, thereby making it smaller and faster. This is very desirable for us as this function is called a lot in any application. It's part of the so-called hot-path.

And that's exactly what the new signature does. It removes the need for us to pull out key from props, add back children to props and just makes the implementation simpler. As a nice benefit users won't need to manually import h/createElement anymore 🎉

// input
<li key="foo">foobar</li>

// output
jsx("li", { children: "foobar" }, "foo");

Usage with babel:

// babel.config.js
module.exports = {
  plugins: [
    ["@​babel/plugin-transform-react-jsx", {
      runtime: "automatic", // defaults to classic (classic == createElement calls)
      importSource: "preact", // NOT preact/jsx-runtime
    }]
  ]
}

Note that the JSX transformer in TypeScript is a work in progress and will likely be released as part of version 4.1. We're currently running into microsoft/TypeScript#40502 though, so the JSX typings are not found.

What a month we had! The weather is getting warmer and I think we can all enjoy a new refreshment in the form of a Preact release! The past weeks saw a good chunk of bug fixes and a bit of house keeping. Upgrades should be as straightforward as swapping out the version number in package.json and running npm install or yarn install once!

Introducing prefresh (experimental)

It was one of those miracle days where all the pieces fell into place just perfectly: @​JoviDeCroock got a HMR (=hot module reloading) prototype up without any changes to Preact and running in a couple hours! With the biggset achievement being that it works amazingly well in keeping hooks state around.

Since then he was contacted by various maintainers of bundlers to collaborate on an ideal developer experience. Today, about a little more than a week later we have them ready to be tested. And we need your feedback to make it the best HMR experience we can! Please file any issue you come across!

• webpack
• vite
• nollup
• Parcel (in progress)
• Snowpack (in progress)

Snowpack template

Oh and while we were at it @​sventschui added a Preact template for snowpack! You can get it up and running via this line:

npx create-snowpack-app my-project --template @​snowpack/app-template-preact

Preact sightings

Recently deno cut it's 1.0.0 release which is a huge achievement. It's a new spin on what node could look like if it would have started fresh in 2019 and we're excited where this experiment will lead to! Despite it being very early it made some waves in our community and we were filled with joy when we noticed that the website is built with our beloved framework!

tl;dr: This release allows our devtools extension to inspect hooks. Apart from that it includes the usual round of bug fixes.

We have a nice little present for you and that is hooks are now fully supported in Preact Devtools 0.5.0 🎉 The extension is currently awaiting approval in browsers stores and your browser will automatically update to it in the following days.

Both @​andrewiggins and @​JoviDeCroock went full on bug hunting mode and got some neat fixes in! We also saw an awesome contribution from @​davidje13 who found an error in our types for memo 👍

But the true star from the show is without a doubt that we finally have updated our typings to bring back the marquee element. @​developit himself took the honors and made sure that developers can continue to use this element in their demo applications.
