Automatic fix: None; review the suggested change
Applies to: Vue SFC templates and blocks, with script context where the rule requires it
Options: No rule-specific options. Severity and preset selection are configurable.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/no-deprecated-v-bind-sync": "error"
      }
    },
  },
});

vp run lint

Bad

The bindings use the removed .sync modifier, including its combination with .camel.

<template>
<MyComponent :title.sync="title" />
<MyComponent v-bind:title.sync="title" />
<MyComponent :title.sync.camel="title" />
</template>

Good

Use an ordinary one-way title binding or v-model:title when an update channel is required.

<template>
<MyComponent :title="title" />
<MyComponent v-model:title="title" />
</template>

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