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
Modern client-side routing: the Navigation API | Web Platform | Chrome for Developers
Single-page applications, or SPAs, are defined by a core feature: dynamically rewriting their content as the user interacts with the site, instead of the default method of loading entirely new pages from the server. While SPAs have been able to bring you this feature via the History API (or in limited cases, by adjusting the site's #hash part), it's a clunky API developed long-before SPAs were the
Insertable streams for MediaStreamTrack | Capabilities | Chrome for Developers
Background In the context of the Media Capture and Streams API the MediaStreamTrack interface represents a single media track within a stream; typically, these are audio or video tracks, but other track types may exist. MediaStream objects consist of zero or more MediaStreamTrack objects, representing various audio or video tracks. Each MediaStreamTrack may have one or more channels. The channel r
URLPattern brings routing to the web platform | Web Platform | Chrome for Developers
Background Routing is a key piece of every web application. At its heart, routing involves taking a URL, applying some pattern matching or other app-specific logic to it, and then, usually, displaying web content based on the result. Routing might be implemented in a number of ways: it's sometimes code running on a server that maps a path to files on disk, or logic in a single-page app that waits
Recognize your users' handwriting | Web Platform | Chrome for Developers
What is the Handwriting Recognition API? The Handwriting Recognition API allows you to convert handwriting (ink) from your users into text. Some operating systems have long included such APIs, and with this new capability, your web apps can finally use this functionality. The conversion takes place directly on the user's device, works even in offline mode, all without adding any third-party librar
Accessing hardware devices on the web | Articles | web.dev
The goal of this guide is to help you pick the best API to communicate with a hardware device (e.g. webcam, microphone, etc.) on the web. By "best" I mean it gives you everything you need with the shortest amount of work. In other words, you know the general use case you want to solve (e.g. accessing video) but you don't know what API to use or wonder if there's another way to achieve it. One prob

Let installed web applications be file handlers | Capabilities | Chrome for Developers
if ('launchQueue' in window && 'files' in LaunchParams.prototype) { // The File Handling API is supported. } The declarative part of the File Handling API As a first step, web apps need to declaratively describe in their web app manifest what kind of files they can handle. The File Handling API extends web app manifest with a new property called "file_handlers" that accepts an array of, well, file
Video processing with WebCodecs | Web Platform | Chrome for Developers
Modern web technologies provide ample ways to work with video. Media Stream API, Media Recording API, Media Source API, and WebRTC API add up to a rich tool set for recording, transferring, and playing video streams. While solving certain high-level tasks, these APIs don't let web programmers work with individual components of a video stream such as frames and unmuxed chunks of encoded video or au
Managing several displays with the Window Management API | Capabilities | Chrome for Developers
Window Management API The Window Management API allows you to enumerate the displays connected to your machine and to place windows on specific screens. Suggested use cases Examples of sites that may use this API include: Multi-window graphics editors à la Gimp can place various editing tools in accurately positioned windows. Virtual trading desks can show market trends in multiple windows any of
Why you need "cross-origin isolated" for powerful features | Articles | web.dev
Introduction In Making your website "cross-origin isolated" using COOP and COEP we explained how to adopt to "cross-origin isolated" state using COOP and COEP. This is a companion article that explains why cross-origin isolation is required to enable powerful features on the browser. Background The web is built on the same-origin policy: a security feature that restricts how documents and scripts
