DataWeave JWT Library

DataWeave JWT Library

This library provides functionality to create signed JSON Web Tokens directly on DataWeave with RSA and HMAC signatures.

Overview

This is a simple example using an HMAC signature:

%dw 2.0
import jwt::HMAC
output application/json
---
HMAC::JWT({
        "firstName": "Michael",
        "lastName": "Jones"
    }, "d4t4w34v3!")

And this is a more complex example, where the key is an input to the transformation:

%dw 2.0
import * from jwt::RSA

output application/json
input key application/json
---
{
    token: JWT(
        {
            iss: "some@email.com",
            aud: 'https://oauth2.googleapis.com/token',
            scope: 'https://www.googleapis.com/auth/drive.readonly',
            iat: now() as Number { unit: 'seconds' },
            exp: (now() + |PT3600S|) as Number { unit: 'seconds' }
        },
        key
    ),
    expiration: now() + |PT3550S|
}

NOTE: The input directive does not work within Mule because inputs there are managed by Mule itself. In that case, you would be able to reference the payload or vars directly.
