Module name "request" has not been loaded yet for context: _. Use require([])

Question

I'm trying to load a function that returns a JSON to me on an HTML page in order to create a table.

Is is there a way to be able to launch that function and the JSON body of return insert it in a variable present in the HTML to be able to transform it into a table?

odatafunction.js

let Request = require("request");
const EventEmitter = require("events").EventEmitter;
const risultato = new EventEmitter();
let keys;
function createArrayKey(array, object) {
    let key = Object.keys(object);
    for (let i = 0; i < Object.keys(object).length; i++) {
        if(i === 0){
            array += object[key[i]];
        }else{
            array += "," + object[key[i]];
        }

    }
    return array;
}

function removeDuplicates(array, key) {
    let lookup = {};
    let result = [];
    array.forEach(element => {
        if (!lookup[element[key]]) {
            lookup[element[key]] = true;
            result.push(element);
        }
    });
    return result;
}


function check_missing_value(new_object2, max_key) {
    var breakLoop = false;
    var miss;
    for(var i=0; i<Object.keys(new_object2).length ; i++){
        miss = -1;
        for(var j = 0; j < Object.keys(max_key).length && !breakLoop ;j++){
            //console.dir(max_key[j]);
            if(!Object.keys(new_object2).includes(max_key[j])){
                new_object2[max_key[j]]="NULL";
                breakLoop = true;
            }

            }
        }


    return new_object2;
}
