405: Elasticsearch → Postgres Search

Alex & Chris get into a fairly recent technological change at CodePen where we ditched our Elasticsearch implementation for just using our own Postgres database for search. Sometimes choices like this are more about team expertise, dev environment practicalities, and complexity tradeoffs. We found this change to be much better for us, which matters! For the most part search is better and faster. Postgres is not nearly as fancy and capable as Elasticsearch, but we werent taking advantage of what Elasticsearch had to offer anyway.

For the power users out there: it’s true that we’ve lost the ability to do in-code search for now. But it’s temporary and will be coming back in time.

Chris’ Corner: Pretty Palettes

I’m not terribly good at picking a good color palette out of thin air. My go-to is a dark look with bright colored accents, but I’m wildly envious whenever I see a beautiful website with great looking colors that are very far away from what I could pull off.

Sometimes, a little inspiration can go a long way. Here’s some!

Color Lisa

Color Lisa is a curated list of color palettes based on masterpieces of the worlds greatest artists. Each palette was painstakingly created by color obsessed designers, artists, museum curators, and masters of color theory.

Flexoki

Flexoki is minimalistic and high-contrast. The colors are calibrated for legibility and perceptual balance across devices and when switching between light and dark modes.

🥳 CSS functions have arrived*!!! 🥳

And they are *AWESOME*

Now, you can do:

@function --alpha(--color, --opacity) {
result: rgb(from var(--color) r g b / var(--opacity));
}

div {
background: --alpha(red, 80%);
}

Chris’ Corner: Clever Clever

David Darnes made a <code-penweb component, which is a basic HTML/CSS/JS panel layout that renders them into an iframe (using the very cool <syntax-highlightweb component as well).

Then it ate itself when Ariel Salminen put a <code-penin a <code-pen.

Then the universe collapsed upon itself when Rob Rhoades made a code pen linking to a code pen inside a <code-peninside a CodePen.

Speaking of, uhhhh, eating oneself, Julia Miocene has a video of a Recursive square that is a very satisfying watch. I almost forgot what was happening up until the end when you’re like ohhhhhhhh right it’s a perfect loop. Clever clever.

There is a thing you need to do once in a while where the more text you have, the smaller you want the font-size to be (and vice-versa). I remember doing this ages ago on a quotes site where I wanted very short quotes in big text and very long quotes in small text. I counted the letters in PHP and applied a font size based on ranges. It wasn’t pretty. Dave blogged that (as long as you have the character count as an HTML attribute) you can do this in CSS (in supporting browsers). You set an “ideal” number of characters per line, then do a little division to get a ratio, and apply the ratio to the font-size (while setting a clamp-ed minimum and maximum). Clever clever.

I liked the Zach’s clever thinking in his Eleventy Image project where, when display an image that starts as SVG, it converts them to a raster format (like PNG or JPG) only when the converted image is actually smaller. Like it’s smart enough to pick which choice to make depending on file size. Or maybe I just like the name: SVG Short Circuiting.

Cassidy blogged a little while back a fairly succinct way of figuring out an element’s “index” when you need it. That is, say a

contains three elements, and you click the second one. How do you know it’s the second one? Go up the parent, get an array of the children, and check the indexOf of the button. (Clever, clever.) I actually think it’s more interesting that we’ll have this information in CSS soon with sibling-index() and friend (sibling-count()).
The pseudonymous dade blogged an idea that I’m pretty surprised I’d never seen before now, as it feels like an old school progressive enhancement technique. If you need to hide a feature on the page that you know only works with JavaScript, you can put a
Clever, clever.

407: Our Own CDN

Robert and Chris jump on to talk about own own little CDN project. Maybe that’s not the right term, but we struggled with naming it. Truth be told, it’s the /public/ folder in our monorepo, where the purpose is getting files to the world wide internet at URLs that anyone can access. Our favicon is a good example, where many of our sites need access to that, but we only want it once in our repo (but we have actually lots of use-cases.)

There are several complications along the way. One is that we need to fingerprint these files so we can cache-bust them when needed. We also need to be able to import the URLs in other parts of the repo, so we need manifest files that contain those URLs in multiple formats. Plus many of the files have their own build process, they aren’t just entirely static files. In the end, building our own thing was probably the right move.

The files go to Cloudflare R2, which, I suppose, is the CDN part.
