Content Validator

Build a simple content validation tool that checks if user-generated text contains any linkifiable patterns (URLs, emails, etc.) and can be used to flag content for moderation.

Requirements

Create a validation function that:

1. Accepts a text string as input
2. Returns a boolean indicating whether the text contains any detectable links or link-like patterns
3. Works with various types of linkifiable content including:
   • HTTP/HTTPS URLs (e.g., http://example.com, https://example.com)
   • URLs without protocols (e.g., example.com, www.example.com)
   • Email addresses (e.g., user@example.com)
   • FTP links (e.g., ftp://files.example.com)

The function should be efficient and handle edge cases like text with no links, empty strings, and text with multiple links.

API

/**
 * Checks if the given text contains any linkifiable patterns
 * @param {string} text - The text to check for links
 * @returns {boolean} True if text contains at least one link pattern, false otherwise
 */
function hasLinks(text) {
  // IMPLEMENTATION HERE
}

module.exports = { hasLinks };

Test Cases

• When given text with an HTTP URL like "Check out http://example.com", it returns true @test
• When given text with a domain without protocol like "Visit example.com for info", it returns true @test
• When given text with an email like "Contact us at support@example.com", it returns true @test
• When given plain text without any links like "Hello world", it returns false @test
• When given an empty string, it returns false @test
