reactjs - How to import npm package in react?

Question

I want to import ibantools but it does not work with require. It says require is undefined. How can I use this package?

   const ibantools = require("ibantools")

Answer 1

just use it like this:

import ibantools from "ibantools";

if the package you trying to import doesn't have a default export all you need to do imported as an object called ibantools

import * as ibantools from "ibantools";

and then use it like this ibantools.whateverPropertyYoureLookingFor
