Hyparquet is a zero‑dependency JavaScript library that parses Apache Parquet files directly in the browser or Node.js, using HTTP range requests to fetch only the needed portions of remote files. It provides simple high‑level APIs (e.g., `parquetReadObjects`) as well as low‑level streaming callbacks for efficient column‑oriented reading, making it ideal for web‑based data‑science, analytics, or any application that needs to query large Parquet datasets without a backend server.
