# bee-js Documentation

> bee-js is the official JavaScript/TypeScript SDK for building applications on Swarm, a decentralised storage and communication network.

`bee-js` lets you interact with a local or remote Bee node from Node.js or the browser. It abstracts the Bee HTTP API, handles chunk-level operations, and provides typed utility classes for sizes, durations, and tokens. The Bee node exposes its API on port 1633 by default. For the full unabridged documentation, see [llms-full.txt](https://bee-js.ethswarm.org/llms-full.txt).
