example.js

import { v5 as uuidv5, NIL } from 'uuid';

function stableUuid(namespace, name) {
    return uuidv5(name, uuidv5(namespace, NIL))
}

// > stableUuid('Some namespace', 'some name')
// '019761ac-2321-5ae0-9086-70c9557bcc58'
// > stableUuid('Some namespace', 'some name')
// '019761ac-2321-5ae0-9086-70c9557bcc58'
// > stableUuid('Some namespace', 'some other name')
