ohmyfetch is a better fetch API. Works on node, browser and workers. import { $fetch } from ‘ohmyfetch’ Import it and use it as you’d use regular fetch. On top of that, you can use some of the extra convenience methods and options — such as easy response parsing, JSON body, Auto Retry, … — …
Tim Broddin — ubernerd and also my tech colleague at VRT Creative Lab — released a very nice Houdini Paint Worklet that draws some smooth blobs. .css-houdini-blobs { –num-blobs: 40; –seed: 4749; –colors: #71a7ee, #7940c1, #f0e891; –min-opacity: 0.1; –max-opacity: 0.5; background: paint(blobs); } Glad to see Tim used css-houdini-circles as a starting point to work …
Saad Quadri created a handy website that lists all ECMAScript Proposals. On one single page you can get a quick glimpse of all proposals and the current stage they are in. Great to see that the various stages of the TC39 Development Process themselves —something I always mention in my ever-evolving talk on ESNext— get …
@scroll-timeline (Part 4)
Just before I left on holiday, the 2nd article I wrote for CSS-Tricks got published. In it, I take a look at the JavaScript side of the Scroll-Linked Animations specification. With WAAPI + ScrollTimeline, a typical “progressbar as you scroll” can be coded like this: const myScrollTimeline = new ScrollTimeline({ source: document.scrollingElement, orientation: 'block', scrollOffsets: …

In this episode of HTTP 203 Jake and Surma go over the code that’s needed to use a Joy-Con (a Nintendo Switch Controller) on the web, which they also use for their own slide decks. As mentioned it’s not possible to get the orientation of the Joy-Con via (the current version of) the Gamepad API. …

A Low Profile Component Framework – Stable, minimal, easy to audit, zero-dependencies and build-tool-free. Basic component definition is really simple: import Tonic from "https://cdn.skypack.dev/@optoolco/tonic" class MyGreeting extends Tonic { render () { return this.html`<div>Hello, ${this.props.name ?? 'Stranger'}.</div>` } } Tonic.add(MyGreeting); Tonic will automatically convert the CamelCased class name to the proper custom element name. <my-greeting></my-greeting> …

Dave Rupert created a little lovely Houdini Paint Worklet that allows you set a background color with an alpha on elements. The Worklet’s code is as simple as this: registerPaint(‘alpha’, class { static get inputProperties() { return [‘–bg-alpha’, ‘–bg-color’] } paint(ctx, size, props) { ctx.globalAlpha = props.get(‘–bg-alpha’); ctx.fillStyle = props.get(‘–bg-color’); ctx.fillRect(0, 0, size.width, size.height); } …
Elijah Manor digs into Date’s toLocaleDateString() and toLocaleTimeString() methods to format Dates and Times in JavaScript, with respect to a passed locale. const date = new Date(); console.log(date.toLocaleDateString(‘en-US’)); // 7/19/2020 const dateOptions = { weekday: ‘long’, year: ‘numeric’, month: ‘long’, day: ‘numeric’, }; console.log(date.toLocaleDateString(‘en-US’, dateOptions)); // Sunday, July 19, 2020 console.log( date.toLocaleDateString(‘fr-FR’, { month: ‘long’, …

From the Polymer team: Tachometer is a tool for running benchmarks in web browsers. It uses repeated sampling and statistics to reliably identify even tiny differences in runtime. To compare two files, run it like so: npx tachometer variant1.html variant2.html Tachometer will open Chrome and load each HTML file, measuring the time between bench.start() and …

Did you know you can import JSON and CSS files just like you import JavaScript Modules? Thanks to Import Assertions, it’s as easy as this: Building upon "Import Assertions" we recently saw JSON Modules land in V8/Chromium 91: “`import json from './foo.json' assert { type: 'json' };“` In Chromium 93 the same thing for CSS …
