async.js

I'm defining a class which instantiates several modules which depend on previous ones. The modules themselves may require an async operation before they are ready (i.e. establishing a mysql connection) so I've provided each constructor with a callback to be called once the module is ready. However I've run into a problem when instantiating classes which are ready immediately: var async = require('async'); var child = function(parent, cb) { var self = this; this.ready = false; this.isReady = function() { return self.ready; } /* This does not work, throws error below stating c1.isReady is

I have an array of arrays of objects called recipesArray. recipesArray = [ [{name = "the recipe name", url = "http://recipeurl.com"}, {name = "the other neame", url = "http://adifferenturl.com"}, {name = "another recipe", url = "http://anotherurl.com"}], [{name = "the recipe name", url = "http://recipeurl.com"}, {name = "the other neame", url = "http://adifferenturl.com"}, {name = "another recipe", url = "http://anotherurl.com"}], [{name = "the recipe name", url = "http://recipeurl.com"}, {name = "the other neame", url = "http://adifferenturl.com"}, {name = "another recipe", url = "http:/

I have a loop in node.js for (var i in files){ var all = fs.readdirsync("./0"); async.eachSeries(all, function(item){ check(item); } } The check(item) has a callback to another function. As I can see, the async.eachSeries doesn't execute synchronously. The loop continues to execute the other items, before the callback in the check() function is finish. How do I make the loop wait until the iteration is finished (including the callback)? Assuming check accepts a callback, we can use mapSeries to achieve that. async.mapSeries(files, function(file, outerCB) { var all = fs.readdirsync("./0");

Been fighting with async module for half a day but can't get it to work properly when nesting few levels. So this works ok: var async = require('async') var myarr = ["Outer - A", "Outer - B"]; var myarr2 = ["Inner - A", "Inner - B"]; var innerComplete = true; async.eachSeries(myarr, function( item, outerCallback) { console.log('Processing item ' + item); async.series([ function(callback) { takeTime(2000, item, callback) }, function(callback) { takeTime(1000, item, callback) }, function(callback) { outerCallback(); } ], function(err) { console.log("---OUTER SEQUENCE---") }) }, function(err){

Using mongoskin, I can do a query like this, which will return a cursor: myCollection.find({}, function(err, resultCursor) { resultCursor.each(function(err, result) { } } However, I'd like to call some async functions for each document, and only move on to the next item on the cursor after this has called back (similar to the eachSeries structure in the async.js module). E.g: myCollection.find({}, function(err, resultCursor) { resultCursor.each(function(err, result) { externalAsyncFunction(result, function(err) { //externalAsyncFunction completed - now want to move to next doc }); } } How
