mosaic-duckdb


A Promise-based Node.js API to DuckDB, along with a data server that supports transfer of Apache Arrow and JSON data over either Web Sockets or HTTP.

_Warning_: Due to persistent quality issues involving the Node.js DuckDB client and Arrow extension, we recommend using the Python-based duckdb-server package instead. However, we retain this package for both backwards compatibility and potential future use as quality issues improve.

_Note:_ This package provides a local DuckDB server for Node.js. To instead use DuckDB-WASM in the browser, use the wasmConnector in the mosaic-core package.
