💡 Vue Tip: Registering Cleanup Callbacks in Watchers
When you register a cleanup callback in a watcher, you can ensure that the cleanup logic is executed when the watcher is destroyed. This is especially useful when you need to clean up resources like event listeners or network requests.
Let's take a look at the following watcher which performs a network request:
But this code has a problem: If idid changes before the request completes, the callback logic executes with the stale ID. To fix this, you can use the onWatcherCleanuponWatcherCleanup function to abort the stale request:
onWatcherCleanuponWatcherCleanup is only available in Vue 3.5 and must be called during the synchronous execution of a watchEffectwatchEffect effect function or watchwatch callback function: you cannot call it after an awaitawait statement in an async function.

Saturday, January 10, 2026 Bob Weir is gone . # Today's song: Playing in the Band . # What's happening with ICE is like January 6 four years later with billions of dollars behind it and many months of planning and studying history for prior art. # As I listened to the mayor of Minneapolis speak I thought he was going say "get the fuck out of Minneapolis" but of course he couldn't say that and then he said it. # I'm doing little demos of stuff I'm working on in WordLand, here's a narrated demo that shows how instant updates are going.

FeedLand has an API, still working on it, but it will be public. 2. FeedLand has an outbound websockets interface , which is already public,...
Saturday, April 5, 2025 I finally looked at my nest egg and was shocked to see the new number. Even worse that the dollars in the account will buy even less as the US dollar loses its value as the flight to safety currency. It's not a big surprise as the US behaves like a drunk Dunning-Kruger deluded schoolyard bully. What is amazing, if you think about it, is that we aren't having an emergency impeachment and trial to get him out of there. That could actually restore a bit of confidence of the outside world, showing that the power in the US is more with the people than it has been for a long time. Maybe our would-be overlords are scared too at what their idea has unleashed. Even if Trump weren't so inept, eventually whoever you choose as the monarch, they're going to behave like this. Inevitable. We could have a revolution right now, fix this, and set the country on the right course. We could do it. I believe we could. # And btw it could be worse ....
