compact

$compact

Strips common formatting characters from a string: whitespace, hyphens, dots, parentheses, and forward slashes. Useful for producing storage-ready representations of formatted values like phone numbers and card numbers.

Characters removed: \\s, -, ., (, ), /

Characters preserved: +, digits, letters, and all other characters.

Example

// Compact a formatted phone number for storage
new Schema('string').normalizer(['$phone', '$compact'])
// '(212) 555-1234' → '2125551234'

// Compact an international phone number (preserves +)
new Schema('string').normalizer([{'$phone': {international: true}}, '$compact'])
// '+1 212 555 1234' → '+12125551234'

// Compact a card number for storage
new Schema('string').normalizer(['$cardnum', '$compact'])
// '4111 1111 1111 1111' → '4111111111111111'
