Declarative partial updates | Blog | Chrome for Developers
Published: May 19, 2026 The web has long since moved on from the static, document-driven medium that it started as. Modern, rich web apps are used by everyone for many reasons, from communicating, purchasing, consuming rich content, to managing our complex lives. HTML, despite all its advances, is still delivered in-order in a top-to-bottom fashion with little regard for when content is ready or w
Announcing Web Serial Support in Firefox – Mozilla Hacks - the Web developer blog
Support for Web Serial in Firefox 151 for Desktop Firefox can now connect directly to microcontrollers, development boards, 3D printers, power meters, and other serial-connected hardware from the web.

Designing the Built-in AI Web APIs
For the last year, I’ve been working as part of the Chrome built-in AI team on a set of APIs to bring various AI models to the web browser. As with all APIs we ship, our goal is to make these APIs compelling enough that other browsers adopt them, and they become part of the web’s standard library. Working in such a fast-moving space brings tension with the usual process for building web APIs. When
Web APIを利用するiOSアプリのテスト技法 - cockscomblog?
もう先週ですが、表題のタイトルで「Consumer Service Engineer MeetUp Vol.1 ~iOS編~」という会でお話しさせていただきました。 このようなタイトルの発表にした理由についてですが、はてなとしてお話しするということで、ちょっと硬派な方に振ってみました。結果としては良いバランスだったのではないでしょうか。 発表資料を掲載します。 また以下に発表の概略を書いておきました。ご参考ください。 前提 このMeet Upの主旨が「コンシューマ向けのWEBサービス（アプリ）の企画・開発・運営をしている会社によるエンジニア向けの講演、パネルディスカッション、懇親会を含めたMeetUpです！」となっていましたので、それではWebサービスとアプリを繋ぐWeb APIについて、それを利用するiOSアプリについて考えます。Web APIというのは古くて新しい話題で、いまや専らJS

Alex Russell on browsers, standards, and the process of progress. One of the things I've poured myself into this year -- with a merry band of contributors including Domenic Denicola, Anne van Kesteren, Jake Archibald, Mark Miller, Erik Arvidsson, and many others -- has been a design for Promises that DOM and JS can both adopt. There's a (very) long history of Promises, Deferreds, and various other

Speed Up App Development with X-Tag and Web Components – Mozilla Hacks - the Web developer blog
In the last few years we’ve witnessed an evolution in what ‘app’ means to both developers and consumers. The word app evokes the idea of a rich, task-oriented user experience with highly optimized user interface that responds to its environment and can be used on an array of common devices. In order to make development of rich app experiences easier, native platforms have generated many of their o

Push notifications for the Open Web | Nikhil's blog
I’m excited to announce a new WebAPI that Mozilla has been working on for the past few months – Push Notifications for Web applications. Push Notifications let web applications be notified that something has changed on the server and that the application should refresh its data. For example, a calendar application can use Push Notifications such that whenever a new event is added on the server, th
