Snippet of component code:
<h2 @click="handleEvent(post.id)">{{ post.title }}</h2>
function handleEvent(id: number) {
router.push("/post/" + id);
}
Error message in TypeScript:
Type '($event: any) => void' is not assignable to type 'MouseEvent'.ts(2322)
__VLS_types.ts(107, 56): The expected type comes from property 'click' which is declared here on type 'EventObject<undefined, "click", {}, MouseEvent | undefined>'
Can you identify the issue?
From my understanding of the situation discussed in this thread, there are two possible solutions:
Important note: Instead of using the "^", it is recommended to set the version specifically as 18.0.0.
I personally opted to install the fixed version of @types/node and it resolved the issue for me.
Summary: To resolve the issue, downgrade your @types/node package to version 18.8.0 until vue 3.2.41 is released.
We encountered a similar problem recently and found a solution that worked for us.
It turned out that there was an incompatibility between vue 3.2.40 and @types/node 18.8.5. The upcoming release of vue 3.2.41 is expected to address this compatibility issue.
Here are the steps we took to fix the issue:
@types/node to version 18.8.0 without using the caret (^)find . -name 'node_modules' -type d -prune -print -exec rm -rf '{}' \\;cmd+shift+p to search for Developer: Reload WindowWe encountered a similar issue where all event handlers in the template were showing errors. This problem started to surface just a few days back. According to the TypeScript definition, event handlers must return types "Event" or "MouseEvent". So, we made the necessary correction in the template like so:
<h2 @click="(e : MouseEvent) => {handleEvent(post.id); return e;}">{{ post.title }}</h2>
Although it now works fine, this doesn't seem to be the ideal way of writing event handlers...
It appears that the recent release of @types/node 18.11.10 has caused some issues with Vue type checking for events. However, a quick solution has been found and a new version has already been released to address this problem:
To resolve this issue, all you need to do is upgrade your @types/node dependency.
