## What it is
Picomatch is a blazing fast, dependency-free JavaScript glob matcher supporting standard and extended Bash glob features like braces, extglobs, POSIX brackets, and regular expressions. It exposes a minimal API that compiles glob patterns into matcher functions and is used by millions of projects including Jest, GraphQL, and Astro.

## Use cases
- match file paths against glob patterns in node.js
- filter files by wildcard patterns like **/*.js
- replace minimatch with a faster glob matcher
- compile glob patterns to regular expressions
- match strings against braces and extglob patterns
- implement file watching with glob-based ignore rules

## When to choose
- you need fast, accurate glob matching with zero dependencies
- you need full support for Bash-style globs including extglobs and POSIX brackets
- you are building a file watcher, bundler, or test runner that filters paths
- you want a tiny API that compiles patterns once for repeated matching

## When to avoid
- you need to actually traverse the filesystem and list files (use fast-glob or globby instead)
- you need glob matching outside JavaScript/Node.js
- you only need simple wildcard matching and want to avoid any dependency

## 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, zero-dependency, wildcard, nodejs, javascript
