JavaScript, TypeScript and frameworks¶

Static coverage

Missing CALLS edges do not mean a function has no callers. Read the module coverage and source before making an absence claim.

Supported bindings¶

The JS/TS pass follows named functions, arrow/function variables, imported aliases, default named exports, namespace imports and explicit named re-exports. It respects local shadowing, destructuring and assignments. It resolves unique relative files and index files within the same root, including unambiguous .js → .ts source substitution. It never matches a bare package name to an unrelated local symbol.

Unresolved constructs¶

This is static source evidence, not proof a call executes. this/object dispatch, constructors, callbacks without indexed Function nodes, callable aliases, CommonJS symbol bindings, wildcard re-exports, framework exports, tsconfig/bundler aliases and external packages remain unresolved. Interfaces and implements do not create runtime INHERITS edges. calls=false disables call edges while retaining structure, imports and supported class inheritance.

Inspect coverage and source sites¶

Every JS/TS or framework Module has a JSON code_coverage STRING: partial mode, call setting, counts of analyzed/resolved/unresolved sites, up to five diagnostic line examples, script count and omitted script types. Missing counters mean zero. These counts describe this analysis, not every possible runtime/template call. The ingest response also reminds agents that coverage is partial. Query it before making an absence claim:

MATCH (m:Module) WHERE m.path = 'src/main.ts' RETURN m.code_coverage
MATCH (f:Function)-[r:CALLS]->(g:Function)
WHERE g.name = 'helper'
RETURN f.path, f.line_start, g.path, g.line_start, r._source, r.sites

Resolved JS/TS edges carry resolution="js-static-v1" and a JSON sites STRING: lines contains up to 32 unique [start,end] source line pairs and total gives the full unique-site count. Repeated calls share one edge. Definition citations and edge sites refer to the original files, including CRLF/Unicode framework files. Dependency export changes refresh affected callers even when their files did not change. Parser revisions also invalidate old indexes automatically.

Vue, Svelte and Astro¶

Framework scripts are parsed as independent units: Vue normal/setup scripts, Svelte module/instance scripts, and Astro TypeScript frontmatter/browser scripts. Prefixes such as instance.run and frontmatter.run distinguish symbols. Existing Vue normal-script IDs stay unchanged; setup symbols use setup.. This pass omits cross-block binding flow and all template expressions, event wiring and compiler transformations. For example, Svelte permits instance code to reference module bindings, but that cross-block call is not resolved yet. Astro frontmatter and browser scripts are different execution environments. See the official Svelte scopes, Vue script setup, and Astro scripts.

HTML comments and inert template/code examples are ignored. External src scripts, unsupported languages/types and files with no supported scripts appear in coverage; syntax errors produce ingestion warnings and leave freshness unverified. The parser uses the existing optional JS/TS grammars and doctor checks all three containers. No compiler, model or additional service is required.
