Question: how to stream array of urls into request?

[Bondifrench]

I am trying to get my head around streams. I have an array of urls and want to call for each url, request, which returns a csv file, that i would like then to process.
I have tried to do it like this:

var es = require('event-stream'),
    request = require('request');

var items =['item1', 'item2',..,'itemN']

var reader = es.readArray(items);

reader
    .pipe(es.map(function (data, cb) {
        var csv = request(data);
        cb(null, csv);
    }))
    .pipe(process.stdout)

but it doesn't work, what would be the correct way to implement this? Thx

Request is a async function, try this way

request(url, function(err, res, body) {
  cb(null, body);
})
