Summary

Closes #16629. Supersedes #22197 by @Eshiv-Pandey, whose commit this keeps, rebased onto current main — it stopped merging after the lib/ regrouping in #22202, so NormalModule moved and lib/NormalModule.js is now a re-export shim. On top of that it fixes three defects found reviewing it: an evaluation error rendered a RuntimeValue through JSON.stringify as {"options":{},"async":true} instead of naming the generator (CodeRabbit's finding, fixed in the shared helper so the pre-existing synchronous path benefits too), one rejection reaching several modules had the key prefixed onto its message once per module, and the beforeParse tap's _ast read failed lint:code on three rules.

What kind of change does this PR introduce?

feat

Did you add tests for your changes?

Yes — the four configCases/plugins/define-plugin-*async* cases and watchCases/plugins/define-plugin-async-runtime-value from #22197, plus new coverage here for the error message, a rejection shared by two modules, and module.parser.javascript.parse.

Does this PR introduce a breaking change?

No. NormalModule's beforeParse becomes an AsyncSeriesHook, so tap keeps working and this plugin is the only in-tree caller; a generator that returned a promise without async used to emit Object({}) and now reports an error.

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

The async option on runtimeValue, that an async generator resolves before parsing, and that beforeParse is now asynchronous — all three are in the JSDoc and reach types.d.ts.

Use of AI

Yes, written with Claude Code. It rebased #22197, investigated and fixed the three defects above, wrote the added tests, and ran the local suites (ConfigTestCases, ConfigCacheTestCases, WatchTestCases, StatsTestCases, HotTestCases, unit) and yarn lint; every result stated here comes from a real run.

Summary by CodeRabbit

  • New Features

    • DefinePlugin.runtimeValue now supports asynchronous resolution before module parsing.
    • Async generators can access module context, dependencies, source information, and dynamic keys.
    • Resolved values support caching and watch-mode updates based on configured dependencies.
    • Async values work across aliases, loaders, custom parsers, and generated modules.
  • Bug Fixes

    • Improved diagnostics when asynchronous values are undeclared or fail during resolution.
  • Tests

    • Added coverage for async substitutions, references, errors, caching, invalidation, and watch mode.

Eshiv-Pandey and others added 2 commits September 20, 2026 17:38
An async runtimeValue generator (or a promise-returning one with
`async: true`) now resolves in NormalModule's beforeParse hook, before
the parser needs it, and is served synchronously at parse time. The
synchronous path is unchanged. A promise returned without `async` throws
a clear error instead of emitting broken code. The beforeParse hook
becomes an AsyncSeriesHook; existing synchronous taps keep working.

closes #16629
…name

`annotateEvaluationError` read a RuntimeValue through `JSON.stringify`,
which drops the generator and leaves `{"options":{},"async":true}` where
the message should name what failed. It also re-prefixed the error it
mutates, so one rejection reaching several modules carried the key once
per module.

A rejection is now kept as it is until a module consumes it, annotated
only then, and the key is prefixed onto it once however many modules
share the instance. Types the `beforeParse` tap's `_ast` read, which
`lint:code` rejected, and covers `module.parser.javascript.parse`.

📝 Walkthrough

Walkthrough

Changes

DefinePlugin now supports asynchronous runtimeValue generators. NormalModule waits for asynchronous beforeParse hooks before parsing. Tests cover resolved values, references, errors, disabled async handling, pre-parse failures, unparsable values, and watch invalidation.

Asynchronous runtime value support

Layer / File(s) Summary
Runtime value resolution
lib/DefinePlugin.js
RuntimeValue accepts promise-returning generators and resolves referenced asynchronous values before parsing. Results and evaluation errors are cached and cleared per module build.
Asynchronous module build flow
lib/module/NormalModule.js
beforeParse uses AsyncSeriesHook. Parsing and parse-error handling now run inside the asynchronous callback.
Resolution and error tests
test/configCases/plugins/define-plugin-async-runtime-value/**, test/configCases/plugins/define-plugin-async-runtime-value-references/**, test/configCases/plugins/define-plugin-async-runtime-value-error/**, test/configCases/plugins/define-plugin-runtime-value-not-async/**, test/configCases/errors/before-parse-error/**, test/configCases/plugins/define-plugin-unparsable-value/**
Configuration cases cover async values, nested and dotted definitions, parser and loader inputs, no-parse modules, pre-parse failures, unparsable values, rejected generators, shared errors, and undeclared or disabled async behavior.
Watch invalidation and release metadata
test/watchCases/plugins/define-plugin-async-runtime-value/**, .changeset/036-define-plugin-async-runtime-value.md
Watch cases cover dependency lists, file dependencies, always-recomputed values, and dynamic versions. The changeset records a minor release.

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. Gzip decides, because that is what users download; raw is the tiebreak, and brotli and zstd are per asset below.

  1. 6 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

  2. No successful run was found on main (a1f0fb1) during the generation of this report, so 3d2bec0 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

`beforeParse` failing is what the hook's move to `AsyncSeriesHook` changed,
and nothing exercised it: a case now fails one module from a `tap` and
another from a `tapPromise`, which covers every line the move added to
`NormalModule` and holds both to the module error the synchronous hook
gave. Two more cases reach an unparsable string define and a code point
above the Unicode maximum.
