Research direction
The issue requests support for URL imports in the eslint plugin import rules. Currently, importing from a URL (e.g., 'https://...') triggers errors about missing dependencies and unresolved paths. To implement this, one should investigate how the plugin resolves imports, particularly in the 'no unresolved' and 'no extraneous dependencies' rules. Look at the import resolution logic in the `resolve` module. Consider adding a check to treat URL imports as external, maybe by checking if the import path starts with 'http://' or 'https://'. There are no linked PRs, but the discussion in the comments may provide additional context. The solution should likely involve modifying the resolver to skip URL imports or treat them as already resolved.
