`vue/no-useless-mustaches`

Disallow a mustache interpolation whose expression is a constant string literal

Default severity: warning
Presets: nuxt, opinionated
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-useless-mustaches": "warn"
      }
    },
  },
});

vp run lint

Bad

The interpolation contains only a constant string and does not need expression evaluation.

<template>
<div>{{ 'x' }}</div>
<div>{{ "x" }}</div>
<div>{{ `x` }}</div>
</template>

Good

Literal text is written directly; variable expressions, interpolated template strings, and intentional separator whitespace remain interpolation cases.

<template>
<div>x</div>
<div>{{ x }}</div>
<div>{{ `pre-${x}` }}</div>
<span>A</span> {{ " " }} <span>B</span>
</template>

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