Advanced JavaScript code search: Abstract Syntax Tree analysis
summary
Proof‑of‑concept builds a JavaScript code search by parsing files with Babel or Acorn into ASTs, flattening nodes to an array and indexing name/type/kind/parentId into an Orama in‑memory full‑text index, so queries return exact locations (example: find a const named FS where parent type is VariableDeclarator). Babel shows ~50M downloads/week so parsing is practical, results return file positions reliably, and the demo suggests adding AI for pattern detection.
