When using glob patterns for file system operations, ensure optimal performance and consistent behavior by configuring glob libraries appropriately and handling paths efficiently:

1. Specify correct options for your glob library:
   • Set expandDirectories: false when replacing libraries like fast-glob with alternatives that have different defaults
   • Use absolute: true when you need absolute paths in results
   • Set appropriate cwd to limit search scope and improve performance

// Less efficient: may search unnecessary directories
const files = globSync(pattern, {
  ignore: ['**/node_modules/**']
})

// More efficient: properly scoped search with correct options
const files = globSync(pattern, {
  cwd: path.resolve(path.dirname(id), dir),
  absolute: true, 
  expandDirectories: false,
  ignore: ['**/node_modules/**']
})

1. Handle path normalization consistently by:
   • Normalizing paths before using them in glob patterns
   • Using regex for efficient path extraction when dealing with complex patterns
   • Setting appropriate options for dotfile handling (dot: true) when needed
2. Optimize node_modules handling in glob patterns:
   • Use regex-based extraction for path segments to avoid unnecessary file traversal
   • Implement path rebasing for patterns that include node_modules to ensure ignore patterns work correctly

Remember that glob operations are computationally expensive, so always consider the algorithmic efficiency of your approach when working with large directory trees.
