• Real-time Validation: Instant form validation with visual feedback and error messages

Core Validation Patterns

1. Title/Author Validation: /^\S(?:.*\S)?$/

   • Purpose: No leading/trailing spaces, allows internal spaces
   • Examples: ✓ "The Great Gatsby" ✗ " Leading space" ✗ "Trailing space "

2. Pages Validation: /^(0|[1-9]\d*)(\.\d{1,2})?$/

   • Purpose: Positive numbers, optional decimals (max 2 places)
   • Examples: ✓ "123" ✓ "123.45" ✗ "0123" ✗ "123.456"

3. Date Validation: /^\d{4}-(0[1-9]|1[0-2])-(0[1-9]|[12]\d|3[01])$/

   • Purpose: YYYY-MM-DD format validation
   • Examples: ✓ "2024-12-25" ✗ "24-12-25" ✗ "2024-13-01"

4. Tag/Category Validation: /^[A-Za-z]+(?:[ -][A-Za-z]+)*$/

   • Purpose: Letters, spaces, and hyphens only
   • Examples: ✓ "Science-Fiction" ✓ "Self Help" ✗ "Fiction123" ✗ "Action!"

Advanced Search Patterns

5. Duplicate Words (Back-reference): /\b(\w+)\s+\1\b/

   • Purpose: Detect repeated consecutive words
   • Examples: ✓ "the the book" ✓ "Dune Dune Chronicles" ✗ "the book review"

6. ISBN Detection: /\b(?:ISBN[-\s]?)?(?:97[89][-\s]?)?\d{1,5}[-\s]?\d{1,7}[-\s]?\d{1,7}[-\s]?[\dX]\b/i

   • Purpose: Identify ISBN-10 and ISBN-13 patterns
   • Examples: ✓ "ISBN 978-0-123456-78-9" ✓ "0-123456-78-X"

7. Author Surname Repetition: /\b([A-Z][a-z]+)\s+\1\b/

   • Purpose: Detect repeated author surnames
   • Examples: ✓ "Smith Smith" ✗ "John Smith"

8. Tag Search Pattern: /^@tag:\w+/

   • Purpose: Special tag-based search syntax
   • Examples: ✓ "@tag:fiction" ✓ "@tag:science" ✗ "fiction"
