Getting a Subset of Fields

Normally, when you read data stored by Telerik Platform, you get all item fields in the response. However, you can choose to receive only a subset of all available fields for each item. This saves bandwidth and can improve your app performance.

To retrieve a subset of the items' fields, specify them using the select() Query method. Note that the Id field is always returned. For example, the following code returns only the Id, Author, and Location fields of each book item.

var el = new Everlive('your-app-id');
var data ='Books');
var query = new Everlive.Query();'Author', 'Location');
data.get(query) // filter
