フルスタックDartからRustバックエンドへ - 10X Product Blog
この記事は10X 新春ブログリレー 2026の1月5日分の記事です。 弊社が提供するネットスーパーのサービスは、モバイルアプリとWebはFlutterアプリ、バックエンドはDartのgRPCサーバーで実装されています。isomorphicではないですが、言語統一がされたフルスタック的な状態と言えると思います。 バックエンドでのDartはマイナーであり、それに伴って様々なデメリットもありました。それらを乗り越えたり飲み込んだりしながら、5年ほどサービスを運用してきましたが、これから先は方針を転換することに決めました。 この記事では、我々が何故フルスタックDartから方針転換することにしたのかと、今後のバックエンドの言語としてRustが有力になっている背景を説明します。 方針転換のきっかけは採用 バックエンドのDartでは様々な問題にぶつかってきましたが、どれも方針転換に踏み切るほどにはならず
History of JS interop in Dart
AI Image generated by GeminiInteroperability has been a core focus from the beginning of Dart. When Dart was first released in 2011, it was designed to be embeddable and multi-platform. It ran on a standalone virtual machine, embedded in a browser, and compiled to JavaScript. When Flutter came along in 2015, we were ready to embed it there, too. Now, we’re excited to target WasmGC runtimes, as wel

Flutter採用で“フルDart”体制へ。スタートアップ10Xが「全社で言語統一」を選ぶ理由 - エンジニアtype | 転職type
2021.01.13 スキル Flutter10XスタートアップCTO 最近流行り始めているGoogleのモバイルアプリ用フレームワーク『Flutter』。iOSでもAndroidでも同じアプリがリリースされることが当たり前となる中、一度に両方のコードを開発できる便利さが注目される理由だ。 「一度触ってみたい」とトップエンジニアの間でも話題になっているが、開発言語はDartと呼ばれる、まだそれほど一般的ではない言語。これまでDartを経験したことがない人にとっては、手を出しづらい側面もあるかもしれない。 そんな中、開発言語を「フルDart」に振り切ってしまった会社がある。開発不要でネットスーパーを垂直立ち上げできるサービス『Stailer（ステイラー）』を提供する10Xだ。 自社に開発リソースがなくてもネットスーパーを立ち上げられるプロダクトとしてコロナ禍で注目を集め、イトーヨーカドーをは

Paint Holding - reducing the flash of white on same-origin navigations | Blog | Chrome for Developers
For a while now, Chrome has eagerly cleared the screen when transitioning to a new page to give users the reassurance that the page is loading. This "flash of white" is this brief moment during which the browser shows a white paint while loading a page. This can be distracting in-between navigations, especially when the page is reasonably fast in reaching a more interesting state. But for pages th
