Specify the block name for the key of the option object.
You can use the object as a value and use the following properties:

  • lang ... Specifies the available value for the lang attribute of the block. If multiple languages are available, specify them as an array. If you do not specify it, will disallow any language.
  • allowNoLang ... If true, allows the lang attribute not to be specified (allows the use of the default language of block).

Note

If the default language is specified for lang option of <template>, <style> and <script>, it will be enforced to not specify lang attribute.
This is to prevent unintended problems with Vetur.

{ script: { lang: 'js' } } ​

Same as { script: { allowNoLang: true } }.
