HTML Standard

Project mention: A Blog Post with Every HTML Element | news.ycombinator.com | 2023-08-13

The article is interesting, but I often come across resources that talk about or reference the HTML5 specification by the W3C. Since 2019, HTML has become a living standard (and therefore no longer has a version number). It is available through Whatwg here: https://html.spec.whatwg.org/multipage/

Test suites for Web platform specs — including WHATWG, W3C, and others

Project mention: We're building a browser when it's supposed to be impossible | news.ycombinator.com | 2023-04-11

We have our own test suite (orginally derived from the test suite of Meta's Yoga layout library [0]) which consists of text fixtures that are small HTML snippets [1] and a test harness [2] that turns those into runnable tests, utilising headless chrome both to parse the HTML and to generate the assertions based on the layout that Chrome renders (so we are effectively comparing our implementation against Chrome). We currently have 686 generated tests (covering both Flexbox and CSS Grid).
We would like to utilise the Web Platform Test suite [3], however these are not in a standard format and many of the tests require JavaScript so we are not currently able to do that.

Fetch Standard (by whatwg)

Project mention: Node.js fetch() vs. Deno fetch(): Implementation details... | /r/Deno | 2023-08-02

I've been testing full duplex streaming from and to the browser using fetch() in a Native Messaging host. (No browser currently support full duplex streaming even though HTTP/2 does, see Fetch body streams are not full duplex #1254).

DOM Standard

Project mention: Using XPath in 2023 | news.ycombinator.com | 2023-07-16

Domenic Denicola (the man who ruined promises) probably will as well.

Streams Standard (by whatwg)

Project mention: Are you using generators? | /r/learnjavascript | 2023-06-30

// AudioWorkletStream // Stream audio from Worker to AudioWorklet // guest271314 2-24-2020 let port; onmessage = async e => { 'use strict'; if (!port) { [port] = e.ports; port.onmessage = event => postMessage(event.data); } const { urls } = e.data; // https://github.com/whatwg/streams/blob/master/transferable-streams-explainer.md const { readable, writable } = new TransformStream(); (async _ => { for await (const _ of (async function* stream() { while (urls.length) { yield (await fetch(urls.shift(), {cache: 'no-store'})).body.pipeTo(writable, { preventClose: !!urls.length, }); } })()); })(); port.postMessage( { readable, }, [readable] ); };

URL Standard

Project mention: When URL parsers disagree (CVE-2023-38633, librsvg) | news.ycombinator.com | 2023-09-07

Browsers have discrepancies too of course. Here's an interesting Chromium bug I've been following: https://bugs.chromium.org/p/chromium/issues/detail?id=125253... and an associated WHATWG discussion: https://github.com/whatwg/url/issues/606

encoding

Encoding Standard (by whatwg)

Project mention: Transcoding Latin 1 strings to UTF-8 strings at 12 GB/s using AVX-512 | news.ycombinator.com | 2023-08-21

Be aware that with the WHATWG Encoding specification [1], that says that latin1, ISO-8859-1, etc. are aliases of the windows-1252 encoding, not the proper latin1 encoding. As a result, browsers and operating systems will display those files differently! It also aliases the ASCII encoding to windows-1252.

File System Standard (by whatwg)

Project mention: persistent storage API on Firefox temporary extension | /r/learnjavascript | 2023-07-24

You can use File System Standard https://fs.spec.whatwg.org/ to write data for that origin (Firefox doesn't implement File System Access API, nonetheless a File object can still be written to local disk using File API).
