Streamlining the Sign-in Flow Using Credential Management API | Web Updates - Google Developers
To provide a sophisticated user experience, it's important to help users authenticate themselves to your website. Authenticated users can interact with each other using a dedicated profile, sync data across devices, or process data while offline; the list goes on and on. But creating, remembering and typing passwords tends to be cumbersome for end users, especially on mobile screens which leads th
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
Chrome supports createImageBitmap() in Chrome 50 | Blog | Chrome for Developers
Decoding images for use with a canvas is pretty common, whether it’s to allow users to customize an avatar, crop an image, or just zoom in on a picture. The problem with decoding images is that it can be CPU intensive, and that can sometimes mean jank or checkerboarding. As of Chrome 50 (and in Firefox 42+) you now have another option: createImageBitmap(). It allows you to decode an image in the b
History API - Scroll restoration | Blog | Chrome for Developers
Using the History API to manage your URLs is awesome and, as it happens, a crucial feature of good web apps. One of its downsides, however, is that scroll positions are stored and then, more importantly, restored whenever you traverse the history. This often means unsightly jumps as the scroll position changes automatically, and especially so if your app does transitions, or changes the contents o
Using requestIdleCallback | Blog | Chrome for Developers
Many sites and apps have a lot of scripts to execute. Your JavaScript often needs to be run as soon as possible, but at the same time you don’t want it to get in the user’s way. If you send analytics data when the user is scrolling the page, or you append elements to the DOM while they happen to be tapping on the button, your web app can become unresponsive, resulting in a poor user experience. Th

Cut and copy commands | Blog | Chrome for Developers
IE10 and above added support for the 'cut' and 'copy' commands through the Document.execCommand() method. As of Chrome version 43, these commands are also supported in Chrome. Any text selected in the browser when one of these commands is executed will be cut or copied to the user's clipboard. This lets you offer the user a simple way to select a portion of text and copy it to the clipboard. This

Jank Free: Let's Make the Web Silky Smooth!
What is Jank? Modern browsers try to refresh the content on screen in sync with a device's refresh rate. For most devices today, the screen will refresh 60 times a second, or 60Hz. If there is some motion on screen (such as scrolling, transitions, or animations) a browser should create 60 frames per second to match the refresh rate. Jank is any stuttering, juddering or just plain halting that user
