disallow key of <template v-for> placed on child elements

  • ⚙️ This rule is included in all of "plugin:vue/vue3-essential", *.configs["flat/essential"], "plugin:vue/vue3-strongly-recommended", *.configs["flat/strongly-recommended"], "plugin:vue/vue3-recommended" and *.configs["flat/recommended"].

📖 Rule Details

This rule reports the key of the <template v-for> placed on the child elements.

In Vue.js 3.x, with the support for fragments, the <template v-for> key can be placed on the <template> tag.

See Migration Guide - key attribute > With <template v-for> for more details.


This rule is targeted at Vue.js 3.x. If you are using Vue.js 2.x, enable the vue/no-v-for-template-key rule instead. Don't enable both rules together; they are conflicting.
