💡 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.

If you're using Vue 3, you're probably using composables. But other than using VueUse where you can, how do you get the most out of them? Over the past few years I've been slowly putting together a list of patterns and best practices for how to write composables in the best way. I've spent hours reading the source code of VueUse (one of the best — but most time-consuming — ways to learn it). I've read articles, listened to talks, and written lots and lots of my own code. I ended up with 15 different patterns, and each one will help you to write better composables. I've condensed and put all of these composables together into a course — Composable Design Patterns. Get Composable Design Patterns now. Because this is the launch, it's on sale for 35% off until Thursday. For each of the 15 patterns in this course, you'll get: A concise overview that tells you when and how to use it, along with variations and edge cases ...
