Modern Cookie Management with the Cookie Store API
Learn how the Cookie Store API modernizes cookie management with async operations and event handling for efficient, error-free web development. The browser Cookie Store API represents a modern approach to handling cookies in web applications. The way we’ve always done it is using document.cookie which is error-prone because you have to work with key/value pairs in a string. Besides being error-pro
Web技術の互換性を把握するためのBaselineとWeb Platform Status Dashboard
Webブラウザの進化に伴い、新しい機能や技術が次々と登場しています。しかし、各ブラウザの実装状況や互換性を把握することは、開発者にとって大きな課題でした。この課題を解決するため、2024年に整備が進み、2025年から本格的に活用できる指標が「Baseline」です。本記事では、2024年に大きく進展したBaselineとWeb Platform Status Dashboardについて紹介します。 Baselineのおさらい Safari、Chrome、Edge、Firefoxといった主要なWebブラウザ間での機能の互換性レベルを体系的に定義し、開発者に明確な指標を提供するものです。これにより、クロスブラウザ開発における予測可能性と信頼性が向上します。 開発者向けの主要なリファレンスプラットフォームであるMDNやCan I Useにおいて、各機能のBaselineステータスがラベルとして明

HTML DOM — Phuoc Nguyen
Web development moves at lightning speed. I still remember when I first started using libraries like jQuery, Prototype, script.aculo.us, Zepto, and many more. Even with modern tools like Angular, VueJS, React, Solid and Svelte, we still have to deal with the Document Object Model (DOM). While these frameworks encapsulate and hide direct DOM management, they still give us access to work with the DO
deliveryType (Resource Timing) · Issue #858 · w3ctag/design-reviews
こんにちは TAG-さん! I'm requesting a TAG review of deliveryType (part of Resource Timing). Resources on the web are usually fetched via HTTP (from the origin server), but in some cases they are known to be delivered from a cache or other buffer, in a way that affects loading performance. Insight into this is useful for authors understanding when these caches accelerate resource loading. The deliveryType
Working together on Interop 2022
From the very beginning, the web was always intended to work in any browser, on any computer. This is possible through interoperability — when each underlying web technology is implemented in the same way in every browser. To reach interoperability, it takes a commitment from all browser engineers to implement web technology according to web standards — the incredibly detailed specifications where
Getting Started With the File System Access API | CSS-Tricks
The File System Access API is a web API that allows read and write access to a user’s local files. It unlocks new capabilities to build powerful web applications, such as text editors or IDEs, image editing tools, improved import/export, all in the frontend. Let’s look into how to get started using this API. Reading files with the File System Access API Before diving into the code required to read
