    Nano Events

    Nano Events

    Simple and tiny (107 bytes) event emitter library for JavaScript

    ...Rather than offering many complex features, nanoevents focuses on the core primitives: creating an emitter, subscribing to named events, emitting events with arbitrary data, and unsubscribing. Because of its minimal API surface and implementation, it’s very easy to integrate into frontend or backend JS/TypeScript projects without introducing significant dependencies or weight. The simplicity reduces cognitive load: developers don’t need to read long docs or worry about advanced event semantics.

    Earth Engine API

    Earth Engine API

    Python and JavaScript bindings for calling the Earth Engine API

    ...With it, users compose lazy, server-side computations over massive catalogs of satellite imagery and vector datasets without handling raw files locally. The API exposes functional operators for map algebra, reducers, joins, and machine learning that scale transparently on Earth Engine’s backend. Developers authenticate once, work interactively in notebooks or the Code Editor, and export results to Cloud Storage, Drive, or asset collections. Visualization helpers render tiled layers and charts so analysts can iterate quickly on workflows like land-cover mapping, change detection, or time-series analysis. By combining petabyte-scale data with concise functional transforms, the API turns complex remote-sensing pipelines into reproducible scripts that are easy to share.
