Enforce valid v-if directives

Default severity: error

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/valid-v-if": "error"
      }
    },
  },
});

vp run lint

Bad

The conditions omit an expression or combine v-if with an else directive on the same node.

<template>
  <div v-if></div>
  <div v-if=""></div>
  <div v-if="ready" v-else></div>
</template>

Good

Each v-if has a nonempty condition such as ready or count > 0, without an incompatible else directive.

<template>
  <div v-if="ready"></div>
  <div v-if="count > 0"></div>
</template>

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