Summary

Passing a string name to SharedWorker loses the name because webpack spreads its characters into an options object. Preserve strings for classic workers and convert them to named options for module workers. Evaluate dynamic arguments once.

new SharedWorker(new URL("./worker.js", import.meta.url), "chat");

// Second argument received with module output, before:
({ 0: "c", 1: "h", 2: "a", 3: "t", type: "module" });
// After:
({ name: "chat", type: "module" });

References: Rspack #15012, SharedWorker constructor specification.

Measured gzip: +36–44 bytes per new SharedWorker fixture bundle; existing worker fixtures unchanged. No runtime modules added.

What kind of change does this PR introduce?

fix

Did you add tests for your changes?

Yes: test/configCases/worker/shared-worker-name/ covers literal, empty, imported and dynamic names, sequence expressions, option objects and ordinary/custom worker handling across classic, module and universal output, with legacy and modern generated syntax. The regression failed before the fix.

Validation: 222 targeted tests pass across ConfigTestCases and ConfigCacheTestCases; all 19 changed executable lines are covered. Full yarn lint and targeted yarn test:size pass.

Does this PR introduce a breaking change?

No.

If relevant, what needs to be documented once your changes are merged or what have you already documented?

n/a; a patch changeset is included.

Use of AI

Used Codex to investigate the regression, implement the fix, add tests and run validation.

Summary by CodeRabbit

  • Bug Fixes
    • Preserved names supplied as string options to SharedWorker constructors, including empty, imported, and dynamically evaluated names.
    • Improved handling of SharedWorker options in module output for string, object, null, undefined, and omitted options. Name expressions are evaluated once, and frozen option objects remain unchanged.
    • Kept existing string-option behavior for regular Worker constructors and custom worker constructors.

📝 Walkthrough

The worker plugin now passes matched syntax names to handlers and applies specialized option handling to SharedWorker syntax. A new config case tests name preservation, option handling, and unchanged behavior for ordinary and custom workers.

Changes: SharedWorker name handling

Layer / File(s) Summary
Pass matched worker syntax
lib/dependencies/worker/WorkerAndWorkletPlugin.js
Handlers receive the matched syntax name instead of a global-Worker boolean. Only Worker receives a constructor range for rewriting.
Handle and test SharedWorker options
lib/dependencies/worker/WorkerAndWorkletPlugin.js, test/configCases/worker/shared-worker-name/*, .changeset/060-shared-worker-string-name.md
SharedWorker string options are preserved as names. Nonliteral options are evaluated once; object options receive module type handling when applicable. Tests cover option forms, qualified syntax, and ordinary and custom worker behavior.

Read Changed, test untouched first: the test is byte-identical on both sides, so webpack generated the difference. Changed, test edited moved partly because the test did — Test edit is how many bytes the test gained, and a bundle that grew by less is not a regression. New and Deleted are whole files, not deltas — a new asset was created, not grown, so it reads gray (⚪ added) — and adding tests cannot bury a real change. Gzip decides, because that is what users download; raw is the tiebreak, and brotli and zstd are per asset below.

No asset that both runs emit changed size — everything below is new or deleted.
