EXT JS Store's Proxy: readers and writers

Question

In the documentation, i have found a store instantiated like this:

var store = Ext.create(\'Ext.data.Store\', {
    autoLoad: true,
    model: \"User\",
    proxy: {
         


        

Answer 1

Actually you are correct - it will use the same url as for reader.

Proxy is a mediator between your model/store on a client and your server code on another side. Readers are used for reading data and you could configure stuff like formatting, specify root etc. Writers are in charge of save/update requests to the server.
