WrappedInternals

A typed proxy for ElementInternals, generated from the latest W3C WAI-ARIA spec with browser support annotations and deep developer experience in mind.

What it solves

* Adds strong typings and intelligent autocomplete for all ARIA attributes on ElementInternals.
* Converts and normalizes native string | null API into proper typed getters/setters.
* Prevents direct mutation of the raw ElementInternals, avoiding API misuse.
* Includes full jsDoc metadata: property descriptions, related ARIA attributes, concepts, and browser support info.

Usage

``ts
import { WrappedInternals } from 'wrapped-internals'

class MyCustomElement extends HTMLElement {
private internals = new WrappedInternals(this)

someMethod() {
if (this.internals.ariaHasPopup === '') return
this.internals.ariaLabel = 'Main menu' // type-checked
}
}
