## What it is
Archiver is a Node.js library providing a streaming interface for generating archive files such as ZIP and TAR, with optional GZIP compression. It supports appending files, directories, globs, buffers, and streams through a unified composition API and can be extended with custom archive formats.

## Use cases
- create zip files in nodejs
- generate tar archives programmatically
- stream files into an archive without loading everything in memory
- compress a directory into a zip for download
- build archives on the fly in an express server
- append streams and buffers to a zip archive

## When to choose
- you need to create ZIP or TAR archives in Node.js with streaming, memory-efficient processing
- you want to pipe archive output directly to files, HTTP responses, or other streams
- you need to mix sources like files, directories, globs, buffers, and streams in one archive

## When to avoid
- you need to extract or read existing archives rather than create them
- you need archive formats beyond ZIP, TAR, and GZIP without writing a custom format plugin
- you are not working in a Node.js environment

## Facets
- artifact type: library
- maturity: stable
- function: compression, file-system, streaming
- domain: files, developer-tools, backend
- platform: -
- tags: zip, tar, gzip, archive-generation, streams, nodejs, javascript
