moving all my old notes from Notion to Obsidian and found this fun one from the first time I tried Vite
Screenshot of an Obsidian page titled "Vite", created on July 1, 2021: Way easier than esbuild because it supports postcss out of the box. Just had to tweak the SVG imports because the plugin is not configurable (would probably want to have our own copy, it's only 40 lines, and ours would probably end up being 30). Only trouble is around multiple entries, which we want for /docs. There are instructions but I couldn't get it to work. An alternative would be to keep it static like we've been doing with webpack, but then oxide-api.json might have to be moved out of api/__generated__. Another perk over Webpack is that it uses Rollup for production builds, so the build ends up being only 400 KB. Pretty cool — seems to save about 100 KB. Sourcemaps look really nice, though there are warnings about svgr not generating sourcemaps. Another reason to make our own copy of the plugin. A couple other things Vite gives you for free: 1. Hashy filenames are generated and (because HTML is the entry) inserted into the HTML. No dealing with stupid manifests. 1. Vendored JS is put in a separate bundle from app source because it's less likely to change. (Confirmed that when I changed the app, only the index bundle hash changed, not vendor)

Big fan of monorepo's. Being able to test the downstream impacts and orchestrate releases from a single repo massively reduced the maintenance burden for everything related to `postcss-preset-env`.

📌 Malicious npm Package Impersonates postcss-selector-parser to Deliver Windows RAT https://www.cyberhub.blog/article/27564-malicious-npm-package-impersonates-postcss-selector-parser-to-deliver-windows-rat
Malicious npm Package Impersonates postcss-selector-parser to Deliver Windows RAT
JFrog security researchers identified an npm package masquerading as postcss-selector-parser that delivers a multi-stage Windows remote access trojan (RAT). The malicious package was designed to impersonate a legitimate dependency, targeting developers who unknowingly install it. The attack chain involves multiple stages, including the execution of obfuscated JavaScript and PowerShell scripts to deploy the RAT payload. No specific dates, CVE IDs, or victim counts were disclosed in the report. The primary impact involves unauthorized remote control of compromised Windows systems.

People need to stop talking trash about web styling technologies and libraries!

Bootstrap is beginner's friendly

Sass is reusable

Bulma is lightweight

Chakra UI is accessible

PostCSS is customizable

Tailwind

Not the end of the world really as worst case I can simply pre-calculate all the values including the line heights, and the problem should (should..) go away.

Welp. Guess I know what I’m doing tomorrow now. Maybe I can have best of both worlds if I can generate compile time vars in PostCSS 🤔

PostCSS is making this a whole lot easier since I can use @function and a few other bits and bobs to reduce duplication (and thus potential for error).

Also considering building a little web based tool to spit out fixed values for when PostCSS isn’t an option, and also because most tools seem to only be concerned with modular font sizes and not the margins that facilitate the rhythm.

Side note, this will be nice when it’s standard.

Same! in Drupal core, that's the **only** reason we keep PostCSS around.

I have used the container query trick before, but there's some places where that's not quite as good.

Bootstrap is unfairly maligned. It is or was overused but the alternative is not that people suddenly develop design skills, it's that a big chunk of the Internet looks even worse and is harder to use.

Sass, however… had its day. Mixed PostCSS/Sass is wild. Not a fan.
