The configuration used to load and save the data items. A data source is remote or local based on the way it retrieves data items.

Remote data sources load and save data items from and to a remote end-point (also known as remote service or server). The transport option describes the remote service configuration - URL, HTTP verb, HTTP headers, and others. The transport option can also be used to implement custom data loading and saving.

Local data sources are bound to a JavaScript array via the data option.

Example - specify the remote service configuration

<script> var dataSource = new kendo.data.DataSource({ transport: { read: { url: "https://demos.telerik.com/service/v2/core/products" } } }); dataSource.fetch(function() { var products = dataSource.data(); /* The result can be observed in the DevTools(F12) console of the browser. */ console.log(products[0].ProductName); // displays "Chai" }); </script>
