## What it is
fdir is an extremely fast directory crawler and globbing library for NodeJS, capable of crawling 1 million files in under a second. It uses a builder-pattern API, has zero dependencies (globbing requires optional picomatch), and ships in under 2KB gzipped.

## Use cases
- list all files in a directory tree quickly
- find files matching glob patterns in NodeJS
- build a directory tree listing
- replace glob or fast-glob for faster file walking
- crawl large file systems with millions of files
- get full paths of files recursively

## When to choose
- you need the fastest possible directory traversal in NodeJS
- you want a tiny, zero-dependency file walker
- you need both sync and async crawling APIs
- you're building tooling like bundlers or linters that scan file trees

## When to avoid
- you need to crawl directories outside NodeJS (browser, Python, etc.)
- you need advanced glob features beyond what picomatch provides
- you need file watching or change detection
- you need cross-platform shell-style globbing with complex brace expansion out of the box
