Postman pre-request-script URL not defined - postman

Question

I have a pre-request-script in Postman which need to create URL:
var uri = new URL(request.url).pathname;
console.log("uri:" + uri);
Which failed with error: URL is not defined. I searched around and tried all different ways:
//const url = require('url');
//const URL = require('url').URL;
None of them work. I check node version and npm, it showed those are on installed
node -v
-bash: node: command not found
npm -v
-bash: npm: command not found
Do I have to install node for this to work?
I also run the code in chrome developer tool console, same result as undefined:
var uri = new URL(request.url).pathname
undefined
But in the same script I also use CryptoJS, which doesn't require any import, it just works.
I'm using macOS Mojave 10.14.6, and POSTMAN 7.21.2 app, not chrome extension.

Postman has support for APIs, some of them are pre-included. CryptoJS, for example, is pre-included, hence you'd not need to add explicitly. The pre-request script has also support for several node modules, to make them work, Postman documentation stated:
In order to use a library, simply call the require function and pass
the module name as a parameter and assign the return of the function
to a variable.
So, in your case, it should be something like:
const url = require('url');
var pathName = url.parse(request.url).pathname;
console.log(pathName);
