Hi! I have created a proof of concept of improving using oxc in JavaScript. The method is not polished but it provides valuable insights for future direction! Feel free to close~ It is for reference only :) # Context This is a proof of concept implementation of passing binary AST to JavaScript. JavaScript can selectively read flexbuffers-based AST nodes on demand to avoid the deserialization toll. More context [here](https://dev.to/herrington_darkholme/benchmark-typescript-parsers-demystify-rust-tooling-performance-2go8). # Changes * Add a `parseSyncBuffer` napi method to return a binary AST from Rust to JavaScript. The AST is in flexbuffer format. * Add a `test_buffer.js` to test usage of flexbuffers in JavaScript. It is in cjs format because flexbuffers does not support ESM :/ # Result Some preliminary results, for reference only. ``` ~ node test_buffer.js testJSON: 4.043s testBuffer: 2.395s ``` Buffer based API is 100% faster than JSON. # Future Ideas * Flexbuffers itself is slow. A better binary protocol is desired! * Using binary reader to traverse AST is undesirable. A proxy-based API to emulate object behavior will be nice.
