It is also advisable, before starting this tutorial, to make sure you have basic knowledge of JavaScript.
What is a UID
A UID (unique identifier), as the name implies, is a unique string across your entire application. It is also known as a GUID (global unique identifier).
To demonstrate UID generation, let's create a service.
Generating UIDs
We will now demonstrate creating a random UID; it is quite simple because Netuno already includes a function specifically created for this purpose:
_out.println(
_uid.generate()
)
Note that the
_out.println()function is only to allow viewing the result on screen when calling the service in the browser
