What categories do input events fall into within Vue?

Question

What Typescript types should be used for input events in Vue to avoid missing target value, key, or files properties when using Event?

For example:

<input @input="(e: MISSING_TYPE) => {}" />
<input @keypress="(e: MISSING_TYPE) => {}" />

In React, we have a generic type called ChangeEvent that applies element-specific types. How can we achieve similar functionality in Vue?

Shoutout to user @steve16351 for the valuable comment providing a summary:

To capture keyboard events such as keypress, you can utilize a more specific event path through Event -> UIEvent -> KeyboardEvent:

<input @keypress="handleKeypress" />

handleKeypress(e: KeyboardEvent) { }

If you require a more targeted event like input change on an HTMLInputElement, casting may be necessary:

<input @input="handleInput" />

handleInput(e: Event) { 
  const target = (<HTMLInputElement>e.target)

  console.log(target.value)
}

I found this solution to be effective when using a standard text input field, even though the recommended answer caused a linting error in my case:

Error: Unexpected token. Did you mean `{'}'}` or `}`?

const onInput = (ev: Event) => {
  const { value = '' } = ev.target as HTMLInputElement;
  // ...
};
