PS. The updated component render you’re seeing streamed to the browser in the previous screenshot is the code rendered by Kitten (showing the underlying HTMX internals, etc.)

The code you write in Kitten is considerably less complicated.

The attached screenshot is all the code in the simple counter example (all in one file, index.page.ts). To run it, you’d just run `kitten` in the directory that file is in and then hit https://localhost.

Screenshot of Helix Editor showing all the code (52 lines) for the stateful counter example, split across two panes so it can be shown at a larger font size: /** Type-safe counter example using stateful Kitten components. */ import kitten from '@small-web/kitten' // Declare database schema and initialise, if necessary. type Schema = { counter?: { count: number } } const database = (kitten.db as Schema).counter ??= { count: 0 } export default class CounterPage extends kitten.Page { counter constructor () { super() this.counter = this.addChild(new Counter()) } override html () { return kitten.html` <page css> <h1>Counter</h1> <${this.counter} /> ` } } class Counter extends kitten.Component { override html () { return kitten.html` <div morph> <div aria-live='assertive'> ${database.count} </div> <button name='update' connect data='{value: -1}' aria-label='decrement'>-</button> <button name='update' connect data='{value: 1}' aria-label='increment'>+</button> <style inline> @scope { div { font-size: 3em; margin: 0.25em 0; } } </style> </div> ` } onUpdate (data: { value: number } ) { database.count += data.value this.update() } }

Very excited about the new stateful components model in Kitten¹ that I’m looking forward to releasing this week (finally) and the amount of visibility you can now get into the flow of your Kitten apps in the Kitten Interactive Shell (REPL)².

Since the new model is a breaking change (Kitten is prerelease) I’m in the middle of updating our own apps/sites and I still need to document everything. So it will take me a few days to do all that but then I’m very much looking forward to focussing on finishing up Catalyst and Yarn³ for launch this year.

It’s been a six year trek to reach what will essentially be the starting point of the Small Web :)
