Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/use-v-on-exact": "warn"
      }
    },
  },
});

vp run lint

Bad

The plain click handler can also run on Ctrl-click, overlapping the separate .ctrl handler.

<template>
  <button type="button" @click="handleClick" @click.ctrl="handleCtrlClick">
    Save
  </button>
</template>

Good

.exact limits the ordinary click handler to clicks without modifier keys; the Ctrl-specific handler remains separate.

<template>
  <button
    type="button"
    @click.exact="handleClick"
    @click.ctrl="handleCtrlClick"
  >
    Save
  </button>
</template>

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