## What it is
fast-glob is a fast and efficient glob matching library for Node.js that traverses the file system and returns paths matching Unix shell-style patterns. It supports multiple and negative patterns, and offers synchronous, Promise, and Stream APIs.

## Use cases
- find all files matching a glob pattern in node.js
- recursively list files in a directory with wildcards
- exclude files with negative glob patterns
- fast alternative to node-glob
- get file paths for a build tool
- match files with brace expansion and globstar patterns

## When to choose
- you need the fastest available glob implementation for Node.js
- you need sync, promise, or stream APIs for file matching
- you need multiple and negative pattern support with rich options

## When to avoid
- you are not working in Node.js
- you need results in a guaranteed sorted order (results are arbitrary order)
- you need full Bash glob semantics without simplifications

## Facets
- artifact type: library
- maturity: stable
- function: file-system, search-engine, developer-tools
- domain: developer-tools, files
- platform: cross-platform
- tags: glob, pattern-matching, filesystem-traversal, wildcard, readdir, command-line, nodejs
