Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "a11y/no-refer-to-non-existent-id": "warn"
      }
    },
  },
});

vp run lint

Bad

aria-labelledby points to save-label, but no element declares that ID.

<template>
  <button aria-labelledby="save-label">Save</button>
</template>

Good

Adding the matching span resolves the reference and provides the button label.

<template>
  <span id="save-label">Save changes</span>
  <button aria-labelledby="save-label">Save</button>
</template>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
