Module: ReactManifest::AstExtractor

Extended by:
Logging
Defined in:
lib/react_manifest/ast_extractor.rb

Overview

AST-based symbol extraction backed by an embedded V8 (mini_racer). Mirrors SymbolExtractor's public interface exactly. Never raises — any parse or runtime failure returns nil (after logging a warning) so the caller (SymbolExtractor's dispatcher) can fall back to regex extraction for that one file.
