What?

Create ModulePart::StarReexports and use it to optimize export *-s

package-star/index.js:

export { notCompiled } from "./not-compiled.js";
export { notExisting } from "./not-existing.js";
export { notExecuted } from "./not-executed.js";
export * from "./not-executed.js";
export * from "./a.js";
export * from "./b.js";
export const local = "local";

package-reexport/index.js:

export * from "package-star";
export const outer = "outer";

import { a } from 'package-reexport' currently creates ModulePart::Export("a") for package-reexport and ModulePart::Exports for package-star.

To make side effect optimization work, we need to create ModulePart::Export("a")for export * from "package-star". There are two solutions.

  1. The first one is making ImportMap and EvalContext parameterized by the requested export symbol name. Obviously, this breaks caching.

  2. Special casing star reexports while analyzing imports, and reuse the requested part if it's an export while determining ModulePart for a dependency (import reference) in references/mod.rs.

The first one is not an option, so I did the second way. But now the problem is where it's used by ModulePart::Internal. We need a way to disable resolution when a package is side-effect-free and we don't use export. Currently, we check for side-effect-free modules in turbopack::apply_module_type, but it's not even called for non-existent files. It's because
origin.resolve_asset in specific_resolve returns ModuleResolveResult::unresolvable.


[turbopack/crates/turbopack-resolve/src/ecmascript.rs:147] request = Request :: Relative {
    path: Pattern :: Constant(
        ./not-existing.js,
    ),
    query: ,
    force_in_lookup_dir: false,
    fragment: ,
}
[turbopack/crates/turbopack-resolve/src/ecmascript.rs:147] result = ModuleResolveResult {
    primary: {},
    affecting_sources: [],
}

The unresolvable error is emitted without control from turbopack-ecmascript.

Why?

To improve tree shaking

How?
