Summary

An imported ESM binding compiles to a namespace read, so a debugger cannot resolve mutable — you have to know it is spelled _lib__WEBPACK_IMPORTED_MODULE_0__.mutable. This adds a -scopes devtool suffix (source-map-scopes, eval-source-map-scopes, …) and the matching SourceMapDevToolPlugin option, emitting the ECMA-426 Scopes field, which names the generated expression each imported binding reads. Emitted code does not change; the cost is bytes in the .map. The encoder itself lives in webpack-sources (webpack/webpack-sources#275, shipped in 3.6.0), so webpack only collects the bindings and hands them over. Refs #3957.

Two things ride along because the dependency bump requires them. 3.6.0 moved its declarations into per-module files ending in export = X, which the type generator turned into import { export= as … } — not an identifier, so lint:special could not parse its own output; such a type is inlined again, as it was while those declarations sat in the package's entry file. And util is added to the webpack-sources module declaration, since webpack.sources.util exists at runtime but was missing from the types.

Known gap, left for a follow-up: a module that concatenation absorbs contributes nothing, because its bindings are collected in the inner code generation and the outer ConcatenatedModule's data does not carry them.

What kind of change does this PR introduce?

feat.

Did you add tests for your changes?

Yes — test/configCases/source-map/source-map-scopes and test/configCases/source-map/eval-source-map-scopes, which run in both ConfigTestCases and ConfigCacheTestCases, plus test/unitCases/DependencyTemplates.unittest.js for the request and the code generation cache key it moves.

Does this PR introduce a breaking change?

No. Nothing is collected or emitted unless the devtool or the plugin option asks for it. It does raise the webpack-sources requirement to ^3.6.0, whose own type layout renames two names in the generated declarations (StreamChunksOptions → OptionsStreamChunks, ConcatSourceChild → Child).

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

The -scopes devtool suffix and the SourceMapDevToolPlugin scopes option.

Use of AI

Yes. Claude Code was used to write the implementation and the tests, to move the encoder upstream into webpack-sources, and to run the suites. The design — bindings collected during code generation and handed to webpack-sources, rather than a codec kept here — was mine, and the encoding was verified byte for byte against Chrome's own @chrome-devtools/source-map-scopes-codec rather than taken on trust.

📝 Walkthrough

Walkthrough

Webpack adds local names for eligible imported ESM bindings and records those bindings in generated source maps. New options, compiler wiring, stable-export analysis, HMR safeguards, source-map encoding, and validation tests support the feature.

Changes

Imported binding debugging

Layer / File(s) Summary
Configuration and compiler wiring
.changeset/..., lib/config/..., lib/WebpackOptionsApply.js, lib/InitFragment.js, lib/NormalModule.js, schemas/...
Adds optimization.localImportBindings, source-map scopes options, defaults, schemas, compiler wiring, and build metadata.
Local binding analysis and generation
lib/optimize/..., lib/dependencies/..., lib/javascript/...
Tracks stable exports, cycles, accepted modules, and declarable names. Eligible imports receive conditional local bindings while other imports retain runtime export expressions.
Source-map scope collection and integration
lib/util/sourceMapScopes.js, lib/SourceMapDevToolPlugin.js, lib/EvalSourceMapDevToolPlugin.js
Decodes mappings, encodes the scopes field, records import-binding expressions, and integrates scope generation into regular and eval source maps.
Behavior and compatibility validation
test/configCases/..., test/hotCases/..., test/sourceMapScopes.unittest.js, test/Defaults.unittest.js, test/Validation.test.js
Tests local binding names, live bindings, reserved names, accepted imports, source-map scopes, defaults, and schema validation.

Merge Risk: ⚪ Minimal · up to 7e30b

This change improves debugging of eligible ESM imports while retaining namespace reads for live bindings, cycles, and accepted HMR dependencies. No concrete current-head merge-blocking risk is identified.

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.

An imported binding compiles to a namespace read, so a debugger cannot
resolve it under the name the source used. A new -scopes devtool suffix
emits the ECMA-426 scopes field, naming for every imported binding the
generated expression it reads.

It changes no emitted code and costs bytes only in the .map.
@alexander-akait alexander-akait changed the title feat: resolve imported ESM bindings by name in a debugger feat(sourcemaps): emit the scopes field for imported ESM bindings Sep 26, 2026
webpack-sources 3.6.0 publishes the encoder as `util.scopes`, so
`lib/util/sourceMapScopes.js` goes entirely: the devtool plugins call
`util.scopes.addScopesToSourceMap`, and asking code generation to record each
imported binding becomes `dependencyTemplates.enableImportBindingScopes()`, on
the object whose hash already keys the code generation cache.

webpack-sources 3.6.0 moved its declarations into per-module files that each
end in `export = X`. The type generator turned such a symbol into
`import { export= as CachedSourceExportImportClass_1 } from …`, which is not
an identifier, so `lint:special` failed to parse its own output and no
generated file could be checked. Those types are inlined again, as they were
while the same declarations sat in the package's entry file.
@github-actions github-actions Bot added the area: tooling Repo tooling, codegen, CLI entry (tooling/, bin/) label Sep 26, 2026
The binding map reached code generation through a new `DependencyTemplateContext`
property and a getter on the per-module context every module allocates; it is now
read from the `getData` that context already carries, by one method on the import
template both ESM dependencies extend, so `DependencyTemplate` and
`JavascriptGenerator` are untouched. `SourceMapDevToolModuleOptionsPlugin`, which
both devtool plugins already apply with these options, turns the collection on and
moves the code generation cache key, leaving `DependencyTemplates` one field.

An import statement no longer records every specifier it declares, only the
namespaces, which no reference site can answer for: over `three-long` (392
modules, 1223 import statements) that is 25 arrays rather than 2448, and 284 KB
less retained heap at the end of the build, measured over three runs each with a
spread under 73 KB. The emitted `scopes` field, its `names` and the mappings are
byte-identical.
