Started writing my own React bindings for @croquetio, feeling pretty good. gist.github.com/steveruizok/73…
The regular @croquet/react bindings have a lot of boilerplate that's available from their context object (e.g. a viewId) so these bindings folds that stuff in.
It’s still a lot of boilerplate though. Most of the “subscriptions” I’m writing are manually syncing these two data sources (the data published from the model and the React state).
But I have a feeling that there’s more we can do to reduce that boilerplate and improve the experience.
Forcing this thing to play with patches and a zustand store
Let's pretend we only need one way to change the state: by smashing in some deep partial "patch" over the current state
So our model will handle that patch like this, I think. Let's call it an easy model, and we'll extend this one for our app's particular state.
And then we make our "easy state" together with a zustand store, which it will update on change
Then tada! Select out data as needed from the zustand store, and change the state by sending in new patches.
heyy
(collaborative) demo here: youthful-noyce-41aa35.netlify.app
Some initial thoughts: probably better to store dots in a map rather than an array
Maybe this one's better? happy-dijkstra-b60720.netlify.app

Build popular open source library, train
own model on docs + examples (some private?), guarantee that model is updated with every release, sell as integration with user IDEs
Let’s say @threejs went this route. The core product is free (wedge) but AI assisted coding environments sometimes trip over out of date versions or make poor choices based on bad examples in their training data.
The threejs team announced ThreeAssist, an “expert” model fine-tuned on each minor release, fresh docs, etc. Outscores commodity models, produces better results, guaranteed to be true to the given version, etc.

my thoughts on ai + canvas, Jan 2025

🧵sorry
I see a lot of AI uses for the @tldraw SDK. I’d say about 25% of our customers are full on AI apps and another 30% are looking to integrate AI tools into their canvas in the future
No surprise, the most shippable / effective use cases are currently where generated artifacts can augment existing use-cases

nightmare fuel for browser apps. 2GB memory limit and no way(?) to recover once you’re over the limit.
Figma has a “wireframe view” that might help here as a fallback, if it means keeping images etc out of memory, though it would be up to the app to switch into that. (And actually I’m not even sure if that would work)
For tldraw we have a limit of shapes per page and pages per project but it’s still theoretically possible to crash it out via memory depending on your browser.

feels pretty good
Here's the full interaction, complete with hover indicators.

Note that you can interact with text directly either: a) when editing text or b) when the text tool is selected. This will mean you can't create text on top of other text, but I'm guessing this is okay.
props to @djsheldrick for the idea here

In @figma, holding shift while drawing a selection box over items will:
1. select deselected items
2. deselect selected items

Is this the right behavior? Have you ever accidentally selected / deselected items while shift-selecting?
@figma I remember working out some more complicated logic here with a rule like "if any new items are being added to the selection, don't deselect any other items"

Remind me next time to migrate the database before shipping runtime validation 💀
In tldraw’s beta db, there were lots of different versions of our data scattered around, including some from the wild times before we wrote client-side migrations, and some that just included broken data, x = NaN etc.
We’d written validation in order to catch this type of bad data when it came into the app. We didn’t write any recovery from the bad data, the app would just throw as soon as it ran into it.
