Can i import a module without execute it in JavaScript?

Question

Is there a way to import a module into another and run it only when called?

Actually i am importing like this.

import {getData, paginacao} from './restCountries.js'

This seems like an XY question. You might revise to ask about what you're actually trying to accomplish instead. — isherwood

No. Importing a module always causes its initialisation code to run - otherwise there wouldn't be any values that you can use.

If there's code in a module that you don't want to run immediately, put it into a function and export that.

there is a way to detect if your module is being imported or called directly and execute different parts of the file.

This has been answerred in this thread

if (require.main === module) {
    console.log('called directly');
} else {
    console.log('required as a module');
}
