Vite virtual imports not recognized by Knip

[ollejernstrom]

When using vite virual imports "virtual" appears as an unused dependency when running knip.

Example:

import { registerSW } from 'virtual:pwa-register'

Knip output:

Unlisted dependencies (1)
virtual  src/index.tsx

Actual package name: vite-plugin-pwa

How can we translate virtual:pwa-register to vite-plugin-pwa?

[ollejernstrom]

I am not saying we necessarily need to translate it, but maybe knip should not mark these as unused since it is very confusing for users. Either we should ignore them by default when using vite or at least make it clear when using the vite plugin (in the docs perhaps).

🚀 This issue has been resolved in v3.3.3. See Release 3.3.3 for release notes.

Knip no longer sanitizes virtual:* specifiers, so you seem them unaltered in the report, and you can then add them to ignoreDependencies.

Another option could be to ignore them altogether, but that would be harder to implement and it may lead to confusion (not sure as I know virtually nothing about this technique).
