Introducing EmDash — the spiritual successor to WordPress that solves plugin security2026-04-01 The cost of building software has drastically decreased. We recently rebuilt Next.js in one week using AI coding agents. But for the past two months our agents have been working on an even more ambitious project: rebuilding the WordPress open source project from the ground up. WordPress powers over 40%

Astroはなぜ速い？プリフェッチの内部実装を追う
この記事は、フロントパッケージリーディング Advent Calendar 2025 2 日目の記事です。 1 日目の「プリフェッチから学ぶ Web パフォーマンスの最適化」を踏まえ、Astro のプリフェッチ機能にフォーカスして整理したものです。Astro プリフェッチの導入判断や運用設計の理解に活かすことを目的にしています。 Astro のプリフェッチとは Astro のプリフェッチは、MPA（マルチページアプリケーション）での遷移を高速化するためのオプトイン機能です。prefetchを有効化すると、サイト全体にプリフェッチ用のスクリプトが追加され、data-astro-prefetchを付与したリンクをユーザーが操作したタイミングで、次のページをバックグラウンドで取得します。 デフォルトはオプトイン（明示したリンクのみ）で、サイト内リンクのみが対象です。外部リンクには適用されません。

Experimental Fonts API Almost every website these days uses custom fonts. However, it can be surprisingly complicated to get them right: Why do I get a Flash of Unstyled Text? Should I add a preload link? What about preconnect links? Do I self-host or rely on a third-party provider? Fonts can have significant performance implications on your site, affecting your visitors’ browsing experience and i
Next.js PPR と比較して理解する Astro Server Islands
はじめに 2024 年 12 月 3 日、Astro 5.0 がリリースされましたが、v5 の目玉機能の一つが Server Islands です。この記事では、Next.js の Partial Prerendering などの各レンダリングモデルと比較しながら、Server Islands の概要や仕組みについて解説します。 「基本的に Server Islands は Astro 版の Partial Prerendering といえるが、動的なコンテンツの取得方法という点において両者は決定的に異なっており、そのことの帰結として Server Islands はパフォーマンスにおいてやや劣るがポータビリティにおいて勝る」というのが最終的な結論ですが、その結論へと至るまでのあいだで他のレンダリングモデルについても詳しく説明し、Next.js と Astro 両方のレンダリングについて全

Astro ゆく年くる年 2023-2024
8 月 30 日に v3.0 がリリースされ、それから約 3 ヶ月後の 12 月 5 日には v4.0 がリリースされており、メジャーアップデートのペースがやや早かったように感じますね。Astro の co-creator である Matthew Phillips によると、v4.0 における大きな変更の一つに Vite 5 へのアップデートがあり、これはもともと v3.0 に含まれる予定だったのが、Vite 5 のリリースが遅れてしまい、一方で v3.0 の目玉機能である View Transitions を早くリリースしたかったため、まず先に v3.0 をリリースし、その後に v4.0 で Vite 5 を含めるという流れとなり、結果的に v3.0 と v4.0 のリリースが短期間で連続してしまった、という事情があったようです。 GitHub スター数の推移 https://star-
Why I use Astro
Why I use Astro written Dec 13, 2023 I’ve been thinking about writing this since a few months ago when some prominent people in the industry were battling “why I use Next.js” vs “why I use Remix”. Now, I don’t try to claim that this is the thing you should do. It’s just a collection of thoughts on why I use Astro. What works for me. And what works for me might not be what works for you.
