Introduction

Validating UUIDs in JavaScript is crucial for web applications that handle unique identifiers for data objects. JavaScript's regex support enables developers to validate UUIDs effectively.

UUID Regex

The regex for UUID validation in JavaScript conforms to the universally accepted 8-4-4-4-12 format.

The UUID Regex Pattern

Pattern:

/^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$/

How to Validate UUIDs in JavaScript?

To validate UUIDs in JavaScript:


function isValidUUID(uuid) {
    const regex = /^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$/;
    return regex.test(uuid);
}

console.log(isValidUUID("123e4567-e89b-12d3-a456-426655440000")); // true or false

Uses of UUID Regex Validation

  1. Unique Object Identification: Ensuring the validity of UUIDs used in client-side data handling and API interactions.

  2. Client-Side Data Validation: Verifying the format of UUIDs in web forms and application inputs.
