help: eslint error by importing 'PropType'

[qhantom]

I would like to import PropType from nuxt-composition-api module. According to the source code, nuxt-composition-api exposes @vue/composition-api so that I can use PropType without any issues. As far as I see, no error is generated technically but ESLint confuses me here:

Is it just a linting bug or is there anything configured wrongly?

Thanks and happy coding!

@qhantom This is a known issue with that particular rule in eslint and TypeScript code, and is not particular to this project.

I'd recommend ensuring you have eslint set up with the correct parse (see Nuxt recommended config), turning the rule off for TypeScript code (as there is another TypeScript eslint rule) or doing an explicit type import (import type { PropType } ...).

Some background:

• False positive on no-undef with mixed JS & TS codebase eslint/typescript-eslint-parser#416
• [no-undef] Exported interface is marked as unused typescript-eslint/typescript-eslint#131

This issue appeared again for me today after an npm dependency upgrade.

The fix to explicitly import PropType as a type using import type { PropType } from 'vue' still works.
