UUID Regex JS

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

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