fix(js-ts): resolve a call through an ES-module default import to the default export - #2743
import fmt from "./fmt" maps fmt to <module>.default, a name no definition is registered under. So fmt() got no CALLS edge, or a heuristic one when the local name happened to equal the exported function's. Meanwhile the CommonJS module.exports = function form already resolved exact.
Recording the default export. After a JS/TS module's definitions are registered (_ingest_js_ts_module_extras, right after the CommonJS direct-export finalisation), _record_esm_default_export records which definition the module's export default names. The new ImportProcessor.esm_default_exports map is a sibling of commonjs_direct_exports. It covers:
export default function name() / class Name;
an anonymous export default function/arrow, looked up by its registered span (anonymous_L_C);
export default ident;
export { x as default }.
Resolving the call. The direct-import resolver maps an import target ending in .default through that record, exactly as it maps a whole-module require through the CommonJS one. The edge is exact.
Stale state. The record is dropped on re-parse and on file removal, alongside commonjs_direct_exports.
Not in this PR: a default re-export that names another module (export { default } from "./x") is left alone, and so is TS export = x.
Demo
The issue's repro, indexed into Memgraph 3.3 by each tree, then cgr graph callees <proj>.src.main.main.
main: two callees, the CommonJS require (exact) and named (heuristic, because the local name equals the function's). The anonymous function, the arrow and export default hex get no edge.
Unit tests pass: the full suite was not run locally. CI runs it on this push.
New tests added
Integration tests pass
Manual testing (the demo above, against a real Memgraph)
Red/green, in codebase_rag/tests/test_esm_default_import_calls.py. The issue's files, plus an export { pad as default } module and a module with no default export, are indexed by the real GraphUpdater into the in-memory graph from evals. The test reads the CALLS edges out of main.main. Against main, 6 of 8 failed:
test_a_default_import_call_is_an_exact_call_to_the_default_export[anonfn | arrow | ident | aliased]: no edge on main.
Calls imported through JavaScript and TypeScript ES-module default exports now resolve to the correct exported function or class, including named, anonymous, arrow, identifier, aliased, and wrapped exports.
Default-import call resolution remains accurate after incremental updates or reprocessing the importing module.
JavaScript and TypeScript directory imports are resolved correctly, with same-named files taking precedence over directories.
CommonJS call resolution remains supported. Imports from modules without a default export continue to have no resolved target.
… default export
`import fmt from "./fmt"` maps `fmt` to `<module>.default`, a name no
definition is registered under, so `fmt()` got no CALLS edge -- or a
heuristic one when the local name happened to equal the exported
function's -- while the CommonJS `module.exports = function` form already
resolved exact.
After a JS/TS module's definitions are registered, record which one its
`export default` names: a named or anonymous function or class, an arrow
(found by its registered span), `export default ident`, and
`export { x as default }`. The resolver maps a `<module>.default` import
target through that record, as it maps a whole-module require through the
CommonJS one. Both records are dropped on re-parse and file removal.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
JavaScript and TypeScript ingestion now records supported ESM default-export targets. Call resolution uses these targets for calls through default imports. Module update paths restore or clear mappings. Regression tests cover export forms, directory imports, and incremental updates.

Summary
Record ESM default exports codebase_rag/constants/ast_js.py, codebase_rag/parsers/import_processor.py, codebase_rag/parsers/js_ts/module_system.py, codebase_rag/parsers/definition_processor.py
ImportProcessor stores default-export targets. JavaScript/TypeScript ingestion records targets for supported declarations, values, and local aliases. Helpers unwrap supported syntax wrappers, including TypeScript type assertions. Parsing clears a module’s previous mapping.
Resolve and restore default-import calls codebase_rag/parsers/call_resolver.py, codebase_rag/graph_updater.py, codebase_rag/tests/test_esm_default_import_calls.py, codebase_rag/tests/test_php_namespace_qualification.py
CallResolver checks registered targets for default imports. GraphUpdater restores mappings and follows JavaScript/TypeScript directory-import targets. Tests cover exact call targets, incremental updates, CommonJS behavior, and imports without a default export. PHP resolver test setups initialize the module-to-file map.
vitali87/code-graph-rag#3293: Persists and restores module exports during incremental runs, including default-import state.
Suggested reviewers:claude
Merge Risk: Low · previous review 85aeb
Default-import resolution improves substantially, with bounded remaining cases that can omit or misidentify call edges. Mergeable with owner awareness of these edge cases.
Security Architecture Review
Security architecture risk:🔵 Low · up to 85967
The change does not demonstrate new execution privileges or external access. A bounded consistency concern remains: a fresh incremental update can lose default-import relationships that a full index records.
Retained concerns
Low · architecture · inferred: Default-export identity is owned only by process-local parser state, while its CALLS edges persist in the graph. Fresh scoped reingestion restores definitions but not that identity mapping; rebuilding an importing caller with an unchanged provider can discard newly supported exact edges. This makes graph reconstruction depend on updater history. No downstream security-control dependency is established.
Security review details
Security Blast Radius
inferred — Repository-controlled export and import syntax can influence additional static graph relationships through the new mapping. The demonstrated outcome is graph-content selection; no expanded runtime privilege or independently attackable service boundary is established by this flow.
Trust Boundaries and Controls
observed — The new branch validates the recorded target against the existing registry before returning it. Default-export discovery skips source-bearing local-alias re-export statements rather than following another module through that branch.
Resilience and Maintainability Implications
inferred — Normal invalidation reduces stale-target risk, but process-local default-export ownership is incomplete across graph reconstruction. The supported concern is persistent analysis consistency; a resulting authorization bypass or other security failure has not been demonstrated.

Full details: Linked Issues check
Explanation
Issue #2724 requires exact CALLS edges for ES-module default imports of anonymous and named functions, arrows, and identifiers. The PR records each module's default-export target and resolves .default import targets to that definition with exact resolution. The regression tests cover these cases, aliased exports, wrapped and cast values, directory index modules, incremental sync, and scoped reingest. The tests also verify that modules without a default export do not bind a call. Cross-module default re-exports and TypeScript export = remain explicitly out of scope in the PR and are not required by the issue's expected-behavior examples.
Full details: Out of Scope Changes check
Explanation
The changed parser, resolver, graph-update state, constants, and regression tests support default-export recording and default-import call resolution for #2724. State restoration and cleanup support incremental and removal behavior. The PHP test setup changes only provide the module-path map needed by the resolver test fixtures, with assertions unchanged. No demonstrated unrelated production behavior or unrelated test objective appears in the supplied change summary.

The module-scoped fixture is set up before the autouse grammar skip, so
on a base install (Python grammar only) it indexed nothing and the
Unit Tests (base install) job failed every test on the empty graph. It
now skips first, as main's module fixtures do.

`test_mcp_context_scopes_free_text_search_to_the_resolved_project` mocked
`list_projects` as [local, other], but the server's default project is the
name its root derives to, which carries a path hash since #2412. The
check from #2461 refuses a default the graph does not list, so the tool
returned that error before any search ran and the test failed on main
and in every PR's test job. The mocked graph now lists the derived name.

(cherry picked from commit ac11bbb)
The red test jobs here (SonarCloud Analysis, the Sonar gate that waits on it, and/or the Unit Tests matrix) fail one test that is not this PR's: test_context_source_root.py::test_mcp_context_scopes_free_text_search_to_the_resolved_project, red on main too. The test mocks the graph's project list without the hashed project name the server defaults to (#2412), so the #2461 check refuses the call before the search it checks runs. The fix is #2995 (test-only). I ported it here as df945b5; it becomes a no-op once #2995 merges.

Handle directory-index default exports in the new esm_default_exports lookup.
For import f from './dir', the import map stores <project>.dir.default. The lookup strips .default and reads <project>.dir. The exporter dir/index.ts is keyed <project>.dir.index, so an anonymous default export there gets no exact CALLS edge. A fix should also check the <module>.index key when the specifier names a directory. Preserve the file-first precedence.

Resolve the ES default import before the CommonJS lookup.
A default import from ./worker maps to <project>.worker.default. If worker/default.js has a CommonJS direct export, _module_import_targets yields that export first. The call then resolves to worker/default.js, not the export default in worker/index.js. Handle the IMPORT_DEFAULT_SUFFIX case before the CommonJS lookup.
