js‑stellar‑xdr‑json is a lightweight JavaScript library that converts Stellar’s XDR-encoded data to and from human‑readable JSON, exposing helpers to list available XDR types, fetch their JSON schemas, guess possible types for a raw XDR string, and perform encoding/decoding via a WebAssembly core. It’s aimed at developers building Stellar‑related front‑end or Node.js applications who need to work with Stellar protocol messages without dealing directly with binary XDR formats.
