Unlocking the structure of your React applications with the AST
summary
Claim: React components are effectively pure functions of props and state so build‑time AST transforms can add real tooling. Implementation uses Esprima to parse and escodegen/estraverse/esquery to rewrite code, producing a webpack loader that wraps React.createElement calls. Demo runs on TodoMVC demo and shows a live prop‑diff panel and 3D component view. Props are cloned with JSON stringify/parse and published to an event emitter for visualization; the transform is for development use because of serialization and performance costs.
