Part of xyflow, this makes it easy to create node-based UIs where you have interactive components wired together however you choose. There's a Svelte version too.

Spinning up a quick, simple browser extension isn’t that big of a deal nowadays, especially with tools like Extension to kick off a project. Larger extensions are a different story, so it’s neat to learn from the experiences of a team that’s built one.

Think Lodash but newer, faster, smaller, and with tree shaking and built-in TypeScript support. The reference guide shows off the supported functions so far – it’s not quite as extensive as Lodash, but it’s getting there with the goal being “to achieve full feature parity with Lodash.”

✌️ I am not... I repeat, I am not... a "frontend developer", just because I like to write JS.
I'm also not a "backend developer" b/c I like to write communication-oriented code, to manage and transmit data and juggle asynchony and other non-UI stuff.
I'm a middle-end dev. Forever. I build libraries, tools, etc. My product is what another dev uses to build their product.
