HTTP URL String Validator

This package provides a focused utility function to determine if a given string adheres to the structural requirements of an HTTP or HTTPS URL. Currently at version 1.0.3, it is a stable, low-cadence library, primarily maintained for compatibility and reliability rather than frequent feature additions. Its core validation logic is built upon a robust regular expression initially developed by Diego Perini, which is well-regarded for its comprehensive coverage of various URL components. Unlike larger, more feature-rich URL parsing libraries, `is-valid-http-url` offers a lightweight and direct API specifically for string format validation, making it ideal for scenarios where only a quick check for valid HTTP/HTTPS URL syntax is needed without additional overhead.
