Introduction GUID Regex JS

Validating Globally Unique Identifiers (GUIDs) in JavaScript is crucial for web applications that handle unique identifiers for data objects. JavaScript regex provides an efficient method for this purpose. A common regex pattern for GUIDs is /^[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}$/.

GUID Regex JS

The regex pattern for GUID validation in JavaScript checks for the standard hex-digit format.

The GUID 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 GUIDs in JavaScript?

To validate GUIDs in JavaScript:

function isValidGUID(guid) {
    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(guid);
}

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

Uses of GUID Regex Validation

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

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