Module resolve 

Import specifier resolution using oxc_resolver.

Orchestrates the resolution pipeline: for every extracted module, resolves all import specifiers in parallel (via rayon) to an ResolveResult, internal file, npm package, external file, or unresolvable. The entry point is resolve_all_imports.

Resolution is split into submodules by import kind:

• static_imports: ES import declarations
• dynamic_imports: import() expressions and glob-based dynamic patterns
• require_imports: CommonJS require() calls
• re_exports: export { x } from './y' re-export sources
• upgrades: post-resolution pass fixing non-deterministic bare specifier results

Handles tsconfig path aliases (auto-discovered per file), pnpm virtual store paths, React Native platform extensions, and package.json exports subpath resolution with output-to-source directory fallback.

Structs

PlatformFamilyKey

Where a source file sits in a Metro platform-extension family: the directory and base stem shared by <stem>.<platform><ext> and <stem><ext>, plus whether this member carries a platform segment.

ResolveAllImportsInput

Inputs used to resolve imports for a complete extracted project.

ResolvedImport

A resolved import with its target.

ResolvedModule

Fully resolved module with all imports mapped to targets.

ResolvedProject

Resolver output for one extracted project.

ResolvedReExport

A resolved re-export with its target.

ResolvedReplacedModuleTarget

One project-internal module replacement resolved from its declaring source file.

ResolverSession

Reusable per-project resolver state: the resolver instances, package manifests, and workspace canonicalization that do not depend on the specific modules being resolved.

Enums

ResolveResult

Result of resolving an import specifier.

ResolvedSourceEdge

Any source-bearing module edge that resolves one literal specifier.

Constants

OUTPUT_DIRS

Known output directory names that may appear in exports map targets. When an exports map points to ./dist/utils.js, we try replacing these prefixes with src/ (the conventional source directory) to find the tracked source file.

Functions

extract_package_name

Extract the npm package name from a specifier. @scope/pkg/foo/bar -> @scope/pkg lodash/merge -> lodash

extract_package_name_from_node_modules_path

Extract npm package name from a resolved path inside node_modules.

has_react_native_plugin

Whether the React Native or Expo plugin is active, the gate for every Metro platform-extension behavior in the resolver and its consumers.

is_bare_specifier

Check if a specifier is a bare specifier (npm package or Node.js imports map entry).

is_path_alias

Check if a bare specifier looks like a path alias rather than an npm package.

is_valid_package_name

Check if a string looks like a valid npm package name.

platform_family_key

Classify path by its Metro platform-extension family.

resolve_all_imports

Resolve all imports across all modules in parallel.

resolve_all_imports_with_session

Resolve all imports for input, reusing a prebuilt ResolverSession.
