## What it is
A minimal JavaScript glob matching library that converts bash-style glob expressions into RegExp objects. It is the matching library used internally by npm and supports brace expansion, extended glob matching, globstar patterns, and POSIX character classes.

## Use cases
- match file paths against glob patterns in node
- implement .gitignore-style file filtering
- check if a filename matches *.foo
- globstar ** recursive path matching in javascript
- brace expansion pattern matching
- posix character class matching with unicode support

## When to choose
- you need battle-tested bash-compatible glob matching in JavaScript
- you want the same matcher npm uses internally
- you need POSIX character classes with full Unicode support

## When to avoid
- you will pass untrusted user input as glob patterns (ReDoS risk)
- you need Windows backslash path separators in patterns
- you need collating symbol matching like [[.ch.]]

## Facets
- artifact type: library
- maturity: stable
- function: parser, developer-tools
- domain: developer-tools, files, web-development
- platform: cross-platform
- tags: glob-matching, pattern-matching, regex, npm, file-matching, nodejs, javascript
