Summary

Before, a module library entry wrote the default into __webpack_exports__ and read it back through __webpack_exports__default, while a named binding is already exported on demand.

Now HarmonyExportExpressionDependency can hands the binding over the same way, so the non-concatenated output exports it directly and drops the exports object and the define call.

Summary by CodeRabbit

  • New Features
    • Module library entries now expose default expressions through their own bindings for anonymous functions, classes, and object expressions.
    • Module library builds preserve side effects from modules loaded in initial chunks.
  • Bug Fixes
    • Corrected default export handling for on-demand module exports while retaining export helpers for non-inlined entries.
  • Tests
    • Added coverage for expression-based default exports, anonymous export forms, and initial-chunk side effects.

📝 Walkthrough

Walkthrough

The change updates export binding generation and module library inlining. It adds coverage for anonymous exports, default expressions, split entry chunks, and concatenation modes.

Changes

Module library default expression exports

Layer / File(s) Summary
Export binding generation
lib/dependencies/HarmonyExportExpressionDependency.js
The export template reads module metadata, derives onDemand, passes it to HarmonyExportInitFragment, and records each export binding’s finalName.
Module library inlining
lib/javascript/JavascriptModulesPlugin.js, lib/library/ModuleLibraryPlugin.js
Entry-module selection uses a static context-based method. Runtime checks and helper-global scanning now use the current chunk and its modules.
Module library export-form coverage
test/configCases/library/module-export-forms/*, test/configCases/library/module-entry-with-initial-chunk/*, .changeset/041-module-library-default-expression.md
The tests cover anonymous functions, anonymous classes, expressions, split entry chunks, and both concatenation modes. The changeset documents the patch release.

Priority: ⬇️ Low

Change: Refactor

Merge Risk: ⚪ Minimal · up to a2570

The change preserves default-expression bindings for module libraries and adds coverage for export forms and split-entry cases; no actionable merge-blocking risk remains.

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, so adding tests cannot bury a real change.

A pull request that is not going to merge still spent the full CI budget on
it. The seven heavy suites in test.yml were held behind `basic` alone, so a
red `lint` or `unit` launched all 26 integration legs; the eight benchmark
shards were held behind nothing at all, and on #22227 they ran for another 67
minutes after `basic` had already gone red — around 3.3 runner-hours of it.

Hold the test.yml suites behind all three cheap jobs, which are the three a
merge needs anyway, and add a gate job to benchmarks.yml that waits on the same
three check runs before the shards start. The gate only ever stops a pull
request: a push to main still benchmarks unconditionally, because CodSpeed
draws every later comparison against that baseline. It also fails open — a gate
that timed out, could not see the checks, or errored lets the shards run rather
than suppressing them on a guess.

CodSpeed draws every later comparison against that commit's baseline. Its
concurrency group is named rather than derived from `github.workflow`, which
reads as the caller's name once test.yml calls it.

* ci: cancel superseded pull request runs

Four workflows had no concurrency group, so a new commit left the previous
commit's run going: CodeQL analyses both languages, pkg.pr.new publishes a
preview of code that has been replaced, and dependency-review and the labeler
each run again alongside the run they supersede.

Cancel them on a pull request and leave the `main` runs alone, as code-size
and deep-imports already do — code scanning reads a pull request's alerts
against the default branch's last analysis, and every push to main publishes
its own preview, so neither is superseded by anything.

The labeler is keyed on the pull request number rather than on `github.ref`,
which under `pull_request_target` is the base branch — the usual group would
have every open pull request cancelling the others' labelling.

pr-quality only fires on opened/reopened and release.yml only on a push to a
tag, so a new commit supersedes nothing there.

* test(css): compare the color corpus, and group the parser jobs by language

css-parsing-tests has 8366 cases and webpack compared 13 of them — the whole
color half was run only to confirm no crash, with upstream's expected values
discarded. They are CSSOM serializations rather than minifier output, so they
cannot be compared literally; reading both the input and that serialization
through webpack's own folding and canonicalizing to `#rrggbb` does compare,
wherever both land in sRGB. That is 796 cases, and webpack agrees on all of
them — no exception list.

Where it declines to fold (lab, lch, out-of-gamut) the two spellings are not
claims about the same thing, so those stay out rather than becoming noise:
comparing every case reports 5549 differences, essentially all of them that.

The three jobs reading an upstream parser corpus become one matrix, named for
the language rather than for whose repository the fixtures live in — which had
already drifted, since `html5lib` reads WPT for the corpus html5lib-tests
dropped. They differed only in submodule, suite and coverage flag.

* docs: name syntax-equivalence (chrome) among the coverage uploaders

Its matrix row sets `coverage: true` and the job's Codecov step runs on that
flag, so the list of suites to wait for was one short — and the sentence after
it said everything unlisted cannot move the number. A contributor following it
could read a coverage result as final while that job was still running.

…e registry

The module library entry's export definitions are left out of its source and
handed over on demand, which only works where the renderer inlines the entry —
rendered into the module registry instead, the stashed source is put back and
reads the helpers again. The runtime requirements were dropped in both cases,
so a chunk whose entry is executed as a factory called `__webpack_require__.d`
and `.r` that the runtime no longer defined.

Ask what the renderer asks before dropping them: the startup inlines the entry
only when no other chunk of the entrypoint loads with it and no module reads
it, and a chunk whose runtime lives elsewhere lifts its entry to the top level
under the conditions `_getEsmEntryModuleToInline` already states — now a static
so the decision can be made before rendering.

Assert the default export from the emitted library.

The test asserts only keep. The configuration emits an ES-module library but does not validate its default export. Add an explicit expect() check for "main" through the generated library output so a default-expression regression cannot pass this case.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@test/configCases/library/module-entry-with-initial-chunk/index.js` around
lines 6 - 8, Update the test case “should define the export helpers the entry
factory reads” to also assert that the generated library’s default export equals
"main". Keep the existing keep assertion and obtain the default value through
the emitted library output.

Rendered into the module registry, the entry has its export definitions put
back into the factory, and nothing held it to still exposing what they define.
