How to import a JS library into a React application?

Question

I am currently using: https://github.com/naikus/svg-gauge

I would like to configure the library for my specific needs, that is, I cannot use the npm package, since I need to configure the library:

import Gauge from 'svg-gauge';

I moved the gauge.js file to: /assets/libs/gauge.js

And then tried to use it like this:

import Gauge from '../../../assets/libs/gauge';

This does not work ... Is it possible to import this JavaScript library into React, allowing me to customize it?

thank

It seems that the problem with the undeclared variable kin shallowCopy()adds the declaration to line 96 in shallowCopy()like this:

function shallowCopy(/* source, ...targets*/) {
   var target = arguments[0], sources = slice.call(arguments, 1);
   sources.forEach(function(s) {
     for(var k in s) {
       if(s.hasOwnProperty(k)) {
         target[k] = s[k];
       }
     }
   });
   return target;
 }
