What's the difference between UUID, GUID and UDID?

• UUID (Universally Unique Identifier): A sequence of 128 bits that can guarantee uniqueness across space and time, defined by [RFC 4122][rfc4122].

• GUID (Globally Unique Identifier): Microsoft's implementation of the UUID specification; often used interchangeably with UUID.

• UDID _(Unique Device Identifier)): A sequence of 40 hexadecimal characters that uniquely identify an iOS device (the device's Social Security Number, if you will). This value can be retrieved through iTunes, or found using UIDevice -uniqueIdentifier. Derived from hardware details like MAC address.

Is UDID deprecated?

// the main app file
import express from "express";
import loadDb from "./loadDb"; // dummy middleware to load db (sets request.db)
import authenticate from "./authentication"; // middleware for doing authentication
import permit from "./authorization"; // middleware for checking if user's role is permitted to make request

const app = express(),
      api = express.Router();

// first middleware will setup db connection
