How to parse meta tags in node.js?

Question

JavaScript

Good afternoon. It is not possible to pick up the description tag and writing to json does not go as it should.
Can you suggest how to do it right?

var needle = require("needle");
var cheerio = require("cheerio");
var async = require("async");
var request = require('request');
var resolve = require('url').resolve;
var fs = require('fs');
var url = "https://toster.ru";
var results = [];
var q = async.queue(function(url){
        needle.get(url,function(err,res){
        if(err) throw(err);
        var $ = cheerio.load(res.body);
        
              console.log($('description').text());
               console.log($('title').text());
            results.push({
                title: $('title').text(),
                description:$('description').text(),
                href: url                
            });
       
    });
}, 10); 

  q.drain = function(){
    fs.writeFileSync('./data.json', JSON.stringify(results, "", 4));
}

description is not a tag, it's the name of a meta tag. this is how it should be
$('meta[name="description"]').attr('content')
