Overview

Updated at：2025-11-03

This document mainly introduces the installation and use of the BOS JavaScript SDK. Prerequisites include prior understanding of BOS fundamentals, and activated BOS service. If you are not yet familiar with BOS, you can refer to [Product Description](BOS/Product Description/Product introduction.md) and [Developer Guide](BOS/Developer Guide/Development Preparation.md).

The BOS JavaScript SDK works in both browser and Node.js environments, providing developers with a simple and efficient way to use BOS storage services through API calls.
