What's a nicer way to do this? Without having that all_data array around?

gistfile1.js

var qhttp = require('q-io/http');
var _ = require('lodash');


var some_url = "http://localhost:8080/getsome/"

var makeNextUrl = _.bind(String.prototype.concat, some_url);

var all_data = [];
function getData(resp){
	resp = JSON.parse(resp);
	if(resp.nextLink){
		all_data.push(resp.data)
		return qhttp.read(makeNextUrl(resp.nextLink))
					.then(getData);
	} else {
		return all_data.concat(resp.data).join('');
	}
}

qhttp.read(makeNextUrl('0'))
.then(getData)
.then(console.log)
.done()

Can you make that getData(resp) internally have something as simple as

if(resp.nextLink){
   return [].concat(\* call for the next one *\)

I tried it, but it needs to be some deferred object because as it is it just pushes the promise into that array.

bootleg that @mentions don't work on gists...

I would do this recursively. Recursion + async is a tasty combo.

I haven't run this, but consider something like this:

function get_all(initial) {
  return ajax(initial).then(function(result) {
    if(result.next) {
      return get_all(result.next).then(function(inner_result) {
        inner_result.push(result.data);
        return inner_result;
      });
    }
    else {
      return [result.data]
    }
  }); 
}
