No. Dependency means a state/data dependency that would require a UI update.
You never need to explicitly assign tree relationships like parents. Here's the example code from the front page. In this case, `model.clicks` is a dependency.
const model = track({ clicks: 0 });
const app = (
<button onclick={ () => ++model.clicks }>
{ model.clicks } clicks
</button>
);
document.body.append(app);
- rglover 2y agoGotcha. Interesting...how does it work? Sounds like a pretty novel way to solve the problem.
- recursive 2y agoEssentially object proxies. When you invoke a property getter in tracked contexts (like DOM element construction), a dependency is registered for that object property. When you invoke the corresponding setter, the update function for the list of dependencies are notified. That's the idea, in a nutshell. I'm definitely not the first one to come up with this idea, but I hadn't found another UI framework that worked exactly like how I wanted. Solid is kind of close, but not it. Vue has some of this as well, but it's a bit more kitchen-sink in its scope.
- rglover 2y agoThanks for sharing, that's a cool idea. Will have to wrap my head around it a bit more but got me thinking about how to strip vdom.
