# Introduction Scroll-driven animations are a common UX pattern on the web. These are animations that are linked to the scroll position of a scroll container. This means that as you scroll up or down, the linked animation scrubs forward or backward in direct response. Think of interesting effects such as parallax background images or reading indicators which move as you scroll. A similar type of s
We’re happy to announce the inclusion of Javy as a hosted project under the Bytecode Alliance.

We’re excited to share the 5.0.0 release today 🎉 Prisma 5.0.0 contains a lot of changes that improve Prisma’s performance, especially in serverless environments. If you want to learn more about the performance improvements, we wrote a blog post that sums up all the changes we made: Prisma 5: Faster by Default. As this is a major release, it includes a few breaking changes that might affect a smal
2023年7月10日CSS,JavaScript,アニメーション,デザインパターンアニメーションの実装はややこしいからCSS Transitionでできなければ実装したくない、そう思っていませんか?FLIPというテクニックを使うことで、CSS Transitionだけでは実装できないケースでも簡単にアニメーションを実装することができます。 FLIPとは #FLIP とは First, Last, Invert, Play の頭文字から取られた用語であり、アニメーションをこの4つのステップに分割して行うテクニックです。例えば、以下のようなリストの項目に追加、削除、並べかえができるUIに対して、簡単にアニメーションを付けることができます。 上のデモで追加、削除、並べかえを行った時に、項目の座標移動がアニメーションすることがわかると思います。これは CSS Transition だけでは実装する
Summary Boa v0.17 is now available! This is one of the biggest Boa releases since the project started, and after around 7 months of development, we are very happy to present you the latest release of the Boa JavaScript engine. Boa makes it easy to embed a JS engine in your projects, and you can even use it from WebAssembly. See the about page for more info. In this release, our conformance has gro
Please don't import SVGs as JSX. It's the most expensive form of sprite sheet: costs a minimum of 3x more than other techniques, and hurts both runtime (rendering) performance and memory usage. This bundle from a popular site is almost 50% SVG icons (250kb), and most are unused. SVGs in JS have a cost and SVGs don’t belong into your JS bundle. It’s about time to bring back SVG-in-HTML. Let’s take
Sorry it's too late to add this issue, I commented that on the yesterday meeting.

The problems of splice, toSpliced There are many complaints about the old splice method in the community, the main issues of it are: Bad name: splice is a very uncommon word, as word usage frequenc
We are excited to announce the release of the new version of Prettier! We have made the migration to using ECMAScript Modules for all our source code. This change has significantly improved the development experience for the Prettier team. Please rest assured that when using Prettier as a library, you can still use it as CommonJS as well. This update comes with several breaking changes. One notabl
Secretlint v7でCommonJS からES Modulesへの移行を行いました。 Secretlint v7.0.0をリリースしました。Pure ESMへの書き直し この記事では、CommonJS(CJS)からES Modules(ESM)への移行を行った経緯と、移行する方法について紹介します。 CJSからESMへの移行は、率直に言えば単調な作業で、メリットが見えにくい作業です。 しかし、将来的にCJSよりもESMが主流になることは間違いないので、移行することは必要です。 移行の作業は、移行方法が決まれば大部分は機械的な書き換えが可能です。 では、実際にどうやって移行したのかを紹介します。 ESMへの移行の影響は依存元へと連鎖する Secretlintのリポジトリはmonorepoになっていて、だいたい40コぐらいのパッケージが含まれています。 そしてパッケージ間で依存関係があ

As we build sites that are more heavily reliant on JavaScript, we sometimes pay for what we send down in ways that we can’t always easily see. In this talk, Addy explains how and why JavaScript is the most expensive resource your site uses today—especially on mobile and lower-end desktops. Web developers should focus on optimizing JavaScript bundles by keeping them small to improve download speed
