[SalesForce] Web Component can’t find variable `require`

I am trying to use the json2csv javascript package in my Salesforce Web Component, but I get the error: can't find variable 'require'.

I've uploaded the json2csv package as a static resource and am loading it via:

import JSON2CSV from '@salesforce/resourceUrl/JSON2CSV';

export default class MyComponent extends LightningElement {
    /**
     * Variables
     */

    json2csvInitialized = false;

    renderedCallback() {
        if (this.json2csvInitialized) {
            return;
        }
        this.json2csvInitialized = true;

        Promise.all([
            loadScript(this, JSON2CSV)
        ])
        .then(() => {
            var csvString = this.testJson2Csv(json);
            console.log(csvString);
        })
    }

    testJson2Csv() {
        const Json2csvParser = require('json2csv').Parser;
        const fields = ['carModel', 'price', 'items.name', 'items.color', 'items.items.position', 'items.items.color'];
        const myCars = [
            {
              "carModel": "BMW",
              "price": 15000,
              "items": [
                {
                  "name": "airbag",
                  "color": "white"
                }, {
                  "name": "dashboard",
                  "color": "black"
                }
              ]
            }, {
              "carModel": "Porsche",
              "price": 30000,
              "items": [
                {
                  "name": "airbag",
                  "items": [
                    {
                      "position": "left",
                      "color": "white"
                    }, {
                      "position": "right",
                      "color": "gray"
                    }
                  ]
                }, {
                  "name": "dashboard",
                  "items": [
                    {
                      "position": "left",
                      "color": "gray"
                    }, {
                      "position": "right",
                      "color": "black"
                    }
                  ]
                }
              ]
            }
        ];
        const json2csvParser = new Json2csvParser({ fields, unwind: ['items', 'items.items'], unwindBlank: true });
        const csv = json2csvParser.parse(myCars);
        return csv;
    }
}

What am I missing? How else am I suppose to use the parser?
