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
Let installed web applications be file handlers | Capabilities | Chrome for Developers
Now that web apps are capable of reading and writing files, the next logical step is to let developers declare these very web apps as file handlers for the files their apps can create and process. The File Handling API allows you to do exactly this. After registering a text editor app as a file handler and after installing it, you can right-click a .txt file on macOS and select "Get Info" to then
ブラウザで何が起こっているのかを知る Reporting API と ReportingObserver | blog.jxck.io
Intro Web サービスにおいては通常、 Web サーバから取得できるアクセスログやエラーログを取得し解析する基盤を保有するだろう。 しかし、 Web サーバから取得できる情報だけでは、ブラウザで何が起こったのかを知るのは限界がある。 今回は、ブラウザ内で起こったことを知るための Reporting API と、その Report の収集について解説する。 Notice 本記事の大半は 1 年以上前に書いたものだが、そのころは仕様も実装もまだまだ落ち着きが無かった。 仕様 report-uri から report-to への移行期 JFV の採用への不安 実装 ディレクティブの実装がバラバラ ReportingObserver では取れるが default group に自動では飛ばない(未実装) ReportingObserver で取った report が JSON Seriali
Unblocking clipboard access | Articles | web.dev
Unblocking clipboard access Stay organized with collections Save and categorize content based on your preferences. The traditional way of getting access to the system clipboard was via document.execCommand() for clipboard interactions. Though widely supported, this method of cutting and pasting came at a cost: clipboard access was synchronous, and could only read and write to the DOM. That's fine
歴史的遺物callback interfaceの紹介 - Qiita
これはChromium Browser アドベントカレンダーの五日目の記事です。本記事ではWeb IDL規格におけるcallback interfaceとcallback functionという2つのコールバック仕様を説明します。ウェブ開発者を想定読者としていますが、ウェブ開発の役には立たない内容となっていますので、トリビアとしてご活用ください。 二つのコールバックの仕組み ウェブ開発をしている方々はなにかとコールバック関数を使う機会があると思います。一番有名なのはEventTarget.addEventListenerでしょうか。 document.body.addEventListener('click', () => { console.log("you've clicked"); }, false);
Detecting text in an image on the web in real-time
Last year just before the Chrome Dev Summit, Miguel Casas came up to me and showed me something that blew my mind: Face Detection in the browser using the Shape Detection API. Shortly after that Barcode Detection was added that allowed me to update my QR Code scanner so that I no longer had to include a massive (albeit awesome) port of a QR scanning library. The Shape Detection API is still in dev
JavaScript’s new IntersectionObserver
The new IntersectionObserver landed in Chromium about a week ago. I find it pretty awesome and wanted to do a quick run down on it. This new API eliminates a lot of the headaches where you would have to do things like poll the page to determine when a element is visible. For example, I have a tab that is not selected and it contains some widget that needs to size itself. I hacked around it like th
simpl.info
George Floyd October 14, 1973 – May 25, 2020 This site aims to provide simplest possible examples of HTML, CSS and JavaScript. There are shortcuts for many of these pages (see full list). For example, simpl.info/v redirects to simpl.info/video. A list of web development resources is available from bit.ly/webdevres. Submit bug reports, requests and comments at github.com/samdutton/simpl.
Permissions API for the Web | Blog | Chrome for Developers
If you've worked with the Geolocation API before, chances are you've wanted to check if you had permission to use Geolocation without causing a prompt. This simply wasn't possible. You had to request the current position and this would indicate the permission state or cause a prompt to be shown to the user. Not all APIs work this way. The Notifications API has its own way of allowing you to check
HTML5: Network Information API | Envato Tuts+
Introduction One of the most discussed concepts in the world of the web design is responsive web design. Thousands of articles have been written on responsive web design and I therefore won't discuss it in this article. However, responsive web design has an important limitation, responsive web design is for the most part based on the size of the browser's viewport. While this approach works well f
