A modular JavaScript and TypeScript library for geospatial analysis and GeoJSON manipulation.
Turf is a modular geospatial engine written in JavaScript and TypeScript that provides a comprehensive library for spatial analysis. It solves the problem of performing complex geospatial operations—like calculating distances, creating buffers, or analyzing spatial relationships—directly within JavaScript applications, eliminating the need for external GIS servers or complex backend setups.
JavaScript and TypeScript developers building mapping applications, location-based services, or any software requiring geospatial analysis, including web developers, GIS professionals, and data scientists working with spatial data.
Developers choose Turf because it offers a pure JavaScript solution for geospatial processing, with a modular design that allows for lightweight imports, broad browser and Node.js support, and a rich set of functions that rival traditional GIS tools, all within a familiar ecosystem.

Functions are packaged as independent modules, allowing lightweight, targeted imports that reduce bundle size and improve performance in client-side applications, as highlighted in the README's emphasis on modularity.
Runs seamlessly in modern browsers and on Node.js servers, enabling consistent geospatial logic across full-stack JavaScript applications, with broad runtime support per the README.
Provides extensive helper functions for creating, validating, and manipulating GeoJSON data structures, making it easy to work with standard spatial formats, as noted in the key features.
Includes a wide range of traditional operations like buffering, intersection, and distance calculations, rivaling traditional GIS tools for advanced mapping and location-based features.
Officially supports only Node.js and browsers, with no guarantees for emerging runtimes like Deno or Bun, which could hinder adoption in some environments, as the README explicitly states.
Being a JavaScript library, it may not match the performance of native or compiled geospatial libraries for CPU-intensive operations on large datasets, potentially slowing down data-heavy applications.
The modular design requires careful management of individual function imports, which can lead to versioning issues and increased setup overhead compared to monolithic libraries.
