mod.rs

1//! Import specifier resolution using `oxc_resolver`.
2//!
3//! Orchestrates the resolution pipeline: for every extracted module, resolves all
4//! import specifiers in parallel (via rayon) to an [`ResolveResult`], internal file,
5//! npm package, external file, or unresolvable. The entry point is [`resolve_all_imports`].
6//!
7//! Resolution is split into submodules by import kind:
8//! - `static_imports`: ES `import` declarations
9//! - `dynamic_imports`: `import()` expressions and glob-based dynamic patterns
10//! - `require_imports`: CommonJS `require()` calls
11//! - `re_exports`: `export { x } from './y'` re-export sources
12//! - `upgrades`: post-resolution pass fixing non-deterministic bare specifier results
13//!
14//! Handles tsconfig path aliases (auto-discovered per file), pnpm virtual store paths,
15//! React Native platform extensions, and package.json `exports` subpath resolution with
16//! output-to-source directory fallback.
