Node JS to scrape table with table-scraper but failed

Question

I am new to NodeJS. I want to scrape table(s) from a page with the package table-scraper but failed, can anyone help me out? My code is as follows:

var http = require('http');

var scraper = require('table-scraper');
scraper
    .get('https://en.wikipedia.org/wiki/List_of_countries_by_GDP_(nominal)_per_capita')
    .then(function(tableData) {

    });

http.createServer(function(req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end(`<p>tableData</p><p> ${tableData} </p>`);
}).listen(8080);
