  javascript json node.js object asynchronous
  I am new to Node and struggling to access a simple JSON object. My request.body will have JSON content similar to the following:{“store_config”: [{“name”: “hello”,”name2″: “world”}] }The “store_config” value will always be present, however the keys and values within could be anything.How can I iterate through the keys and values to access each? I would also like to process each in an asynchronous manner.Appreciate any thoughts or direction.UPDATEconsole.log(typeof(request.body));Returns: Objectp

  javascript ajax node.js
  I have an object containing a date object. When I post it to a NodeJS server, it’s still an object but the time has been converted to a string. Is there any way to avoid this? I can’t parse the entire object because I get an “Unexpected token o” error (I assume because it’s still an object). Before:Object {title: ” – fd”, start: Tue Feb 11 2014 09:00:00 GMT-0500 (EST), end: Tue Feb 11 2014 10:00:00 GMT-0500 (EST), allDay: false, id: “”.}After: Object allDay: “false” end: “Tue Feb 11 2014 10:00:0

  node.js global-variables user-agent sails.js controllers
  I am trying to have a variable which can be accessible by all controllers in my node project. Currently in one controller I have:var ua = req.headers[‘user-agent’];var isMobile = “no”;if(/mobile/i.test(ua))isMobile=”yes”;It’s pointless to copy past all of this for all my controllers and pass the isMobile variable to the view. I’d like to get the value of isMobile set once, and then pass it wherever I want from my controllers.Is there an easy way to do this rather than have those 4 lines of code

  node.js angularjs express jade mixins
  Related to that question: Jade Mixins in AngularJSI have the following (simplified) code:tr(ng-repeat=”avatar in avatars”)+avatarRow({name: ‘{{avatar.name}}’})mixin avatarRow(avatar)td avatar.nameSince it is a bit dirty to resolve the “avatar” object before it is passed to the mixin I would prefer a more angular like solution.Still it would be cool, to keep the mixin code in the same file, but thats not a must. As far as I see, with ngInclude I can no pass any args. So how to handle that?Continu

  mysql database node.js scaling multi-master-replication
  I am creating this web application in Node.js and MySQL and I am struggling on data synchronisation. Here’s the scenario:Suppose we have 1000 customers that all have a local webserver-database in their office/site. A user can login, edit data, datalog sensors, etc. All these activities contribute to, for the sake of the example, around 500KB of table data per day, per customer/site. So each of the 1000 customers have a local database that will always constantly get updated with new data many tim
