xity
Developer tools for the extended city
$ npm install @xity/coreWhat is xity?
xity is an open-source framework for building city-scale digital infrastructure. It provides typed APIs for geospatial data, real-time transit feeds, IoT sensor networks, and civic data pipelines — everything a developer needs to build applications that understand urban environments.
Typed Urban Data
Every data type in xity is fully typed with TypeScript definitions. From GeoJSON geometries to GTFS transit schedules, the SDK provides compile-time safety and IDE autocompletion for the most complex urban datasets.
Plugin Ecosystem
Connect to municipal open data portals, weather services, traffic APIs, and sensor networks through a unified plugin interface. Each integration is independently versioned and lazy-loaded for minimal bundle impact.
City-Scale Efficiency
Built on WebAssembly for computational geometry, streaming parsers for large datasets, and worker-thread parallelism for real-time data processing. xity handles millions of data points without blocking the main thread.
