Delay each loop iteration in node js, async

Question

I have the code below:

var request = require(\'request\');
var cheerio = require (\"cheerio\");
var async= require(\"async\");

var MyLink=\"www.mylink.com\"         


        

Answer 1

Another alternative would be to use async.eachSeries. For example:

async.eachSeries(TheUrl, function (eachUrl, done) {
    setTimeout(function () {
        var url = 'www.myurl.com='+eachUrl;
        request(url, function(error, resp, body) { 
            if (error) return callback(error); 
            var $ = cheerio.load(body);
            //Some calculations again...
            done();
        });
    }, 10000);
}, function (err) {
    if (!err) callback();
});
