nodejs-polars

nodejs-polars is a Node.js binding for the Polars DataFrame library, built on Rust for performance. Version 0.24.1 requires Node >= 20, ships TypeScript types, and supports ESM and CJS. It provides fast data manipulation via lazy and eager APIs, with features like groupby, join, sort, and window functions. Key differentiators: significantly faster than pandas, lower memory usage, and a more expressive API. Released frequently (weekly/monthly), tracking the Rust core.
