How to properly import npm modules into browser js?

Question

JavaScript

I have a js code that needs to be run in a browser, with the following syntax:

import { something } from 'module1'
import { something } from 'module2'

...

module1 and module2 are modules from npm. Tried Browserify but it throws an error:

ParseError: 'import' and 'export' may appear only with 'sourceType: module'

. On the Internet, unfortunately, I did not find anything sensible about this.
