Cronbake Parser – Cron Expression Parsing for the Browser

This package provides a powerful cron expression parser, originally based on the excellent cronbake library. The parser is designed to work seamlessly in browser environments, making it easy to validate, parse, and compute next/previous execution times for cron expressions on the client side.

  Parse expressions like @every_5_minutes, @at_12:30, and more.
• Human-Readable Field Mapping:
  Understands fields in the order: second minute hour day month day-of-week.
• Validation:
  Check if a string is a valid cron expression before using it.
• Next/Previous Execution Calculation:
  Compute the next or previous run time for any valid cron expression.
• Lightweight & Browser-Friendly:
