Paging with WebSockets in Sails

Question

I have an existing web app with an ExtJS front end and Sails back end. Currently the app uses XHR for data interchange but I wish to switch to Websockets.

Reading the Sails Docs it says that a call to io.socket.get will subscribe the client to the returned set of records. When paging however I'm only interested in receiving server-sent events for the current page of records.

Is there some means of unsubscribing records as the user pages?

Answer 1

io.socket.get() will only subscribe you if you are using the Blueprint API of sails. That being said have a look at find where and set the limit and skip properties accordingly. So you will only be subsribed to the instances which are queried.

var page = currentPage;
var amount = 30;

io.socket.get('/entry?skip=' + page * amount + '&limit=' + amount, function (entries) {});
