UUID v8 Generator

About

UUID Version 8 is reserved for custom, implementation-specific UUIDs. The format allows for vendor-specific or application-specific UUID generation schemes. This version gives you full control over the UUID structure while maintaining the standard UUID format (8-4-4-4-12 hexadecimal digits). Use v8 when you need custom UUID generation logic that doesn't fit other versions, such as embedding application-specific data or using custom algorithms while maintaining UUID compatibility.

Use Cases

• •Custom UUID generation schemes
• •Vendor-specific identifier formats
• •Application-specific UUID structures
• •Embedding custom data in UUID format
• •Experimental or proprietary UUID formats

How to Generate

// Custom v8 UUID implementation
function generateV8() {
  const randomHex = () => 
    Math.floor(Math.random() * 16).toString(16);
  const segments = [
    '8' + randomHex() + randomHex() + randomHex(),
    randomHex().repeat(4),
    '8' + randomHex() + randomHex() + randomHex(),
    randomHex().repeat(4),
    randomHex().repeat(12)
  ];
  return segments.join('-');
}
