disallow unknown locale name

📖 Rule Details

This rule reports the use of unknown locale names.

By default, this rule only commonly known locale names specified in RFC 5646 are allowed. The rule uses the is-language-code package to check if the locale name is compatible with RFC 5646.

<script>
/* eslint @intlify/vue-i18n/no-unknown-locale: "error" */
</script>

<!-- ✓ GOOD -->
<i18n locale="en">
{
  "hello": "Hello!"
}
</i18n>

<!-- ✗ BAD -->
<i18n locale="foo">
{
  "hello": "Foo!"
}
</i18n>
