It'd be good to ensure there's type annotations on these args if possible.

This if-clause is ill-formed. It discards too much information.

This should be handled in the rust parser. If it isn't, it is a bug. See https://github.com/pantsbuild/pants/blob/6f8e16e0a2b78d9b3feeb860b38782b92abd1848/src/rust/engine/dep_inference/src/javascript/tests.rs#L473C4-L473C35

This might also explain why I find the if-clause ill-formed. I think you might have misunderstood or been tricked by a bug in what the intention of ParsedJavascriptDependencyCandidate was. The parser can produce candidates on either form or both, but the separation you do here assumes it knows which case it found. It doesn't. That is why the method is named _determine_import_from_candidates. But like I said, the parser or my assumptions on how to read tsconfig might be bugged.

if local_owners:
owning_targets = await Get(Targets, Addresses(local_owners))

# If package name begins with @, then keep the subpackage name
non_path_string_bases = FrozenOrderedSet(
f"{non_path_string.split('/')[0]}/{non_path_string.split('/')[1]}"

Good catch!

addresses = Addresses(
package_candidate_map[pkg_name]
for pkg_name in non_path_string_bases
if pkg_name in package_candidate_map
)
return addresses

Word of warning that this parses javascript and JSX files, and will fail to parse as soon as it encounters the type keyword, which is a valid qualifier for typescript imports but not JS.

If we're supporting TSX here, should we also support JSX? I'm not sure, just pattern matching.
