vue/no-template-shadow

Disallow variable names that shadow variables in outer scope

Bad · Good

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.

The current check compares nested v-for bindings. It does not report a single v-for binding merely because it shares a script binding's name.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/no-template-shadow": "warn"
      }
    },
  },
});

vp run lint

Bad

The inner v-for declares item again and hides the outer item binding inside the nested loop.

<template>
<div v-for="item in items" :key="item.id"><span v-for="item in item.children" :key="item.id">{{ item.name }}</span></div>
</template>

Good

The inner loop declares child, leaving item available for the outer row and child for the nested row.

<template>
<div v-for="item in items" :key="item.id"><span v-for="child in item.children" :key="child.id">{{ child.name }}</span></div>
</template>

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