## What it is
Knox is a Node.js client library for the Amazon S3 REST API, offering both low-level HTTP-verb methods and higher-level helpers like putFile and putStream. It supports streaming uploads, piping, copying, and multi-file deletes, though it is now deprecated in favor of the official AWS SDK.

## Use cases
- upload files to amazon s3 from node.js
- stream an http response directly into an s3 object
- pipe a file read stream to s3
- delete multiple s3 objects in one request
- copy objects between s3 keys
- sign and send raw s3 rest api requests

## When to choose
- you maintain a legacy node codebase already built on knox
- you want a minimal, node-http-like s3 client without the full aws sdk
- you need simple streaming uploads to s3 with direct pipe support

## When to avoid
- starting a new project - the library is deprecated and the official aws sdk is recommended
- you need support for newer s3 features like multipart uploads, presigned urls, or s3-compatible endpoints with modern auth
- you need long-term maintenance and security updates
