Node Pass Hidden Data To Other Route

Question

Node Pass Hidden Data To Other Route

I have a route in express(item/update/), and after that happens I want to send them back to /, I also want to make / show an alert with 'Success' or 'Failure'. I don't want to use query string or hash because I want it to be hidden from the user. I also don't want to render / at items/update as it seems like a bad idea. Also, I have tried the javascript history api, but that seems like a hack as the history api was for something else.

Please let me know if there is any more information you need, Ari

node.js
data
routes
express
hidden

You can do couple of ways,

1.You can redirect to "/" url with query string. Since you don't like to add data in query string, then alternate option is session.

For example,

function itempUpdateHandler(request,response){
 //Do some stuff
 request.session.displayMsg = "update done successfully";
 response.setHeader("Location: http://yourdomain.com/");
 response.end();
}

function homepageHandler(request,response){
//Display message here which is read from session.
if(request.session.displayMsg){
  console.log(request.session.displayMsg);
  delete request.session.displayMsg;
}
//Do your regular suff here.
}

2.You have to take care somewhat more in following method, here you aren't going to redirect but you need modify you handler function as follows,

function itempUpdateHandler(request,response){
 //Do some stuff
 //response.setHeader("Location: http://yourdomain.com/"); //no need here
 homepageHandler(request,response, {display:true, msg: "update done successfully"});
}

function homepageHandler(request,response, moreArgs){
//Display message here which is read from session.
  if(moreArgs.display){
       console.log(moreArgs.msg);
  }
//Do your regular suff here.
}

Note: Assumed you are using express
