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/this-in-template": "warn"
      }
    },
  },
});

vp run lint

Bad

Template expressions explicitly access this.message, this.className, and this.handleClick, although Vue exposes those bindings directly.

<template>
<div>{{ this.message }}</div>
<div :class="this.className"></div>
<button @click="this.handleClick()"></button>
</template>

Good

Use message, className, and handleClick directly. The literal string 'this.is.a.string' stays unchanged because it is not a member access.

<template>
<div>{{ message }}</div>
<div :class="className"></div>
<button @click="handleClick()"></button>
<div>{{ 'this.is.a.string' }}</div>
</template>

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