Retrieving the Range of Data with a Cursor

Learn about KeyRange and how to use it with a cursor to retrieve data within a specific range.

In IndexedDB, a KeyRange object represents a range of keys in an object store. It can retrieve a specific range of records from the object store.

How to create a KeyRange?

There are several ways to create a KeyRange object:

  • Using the only() method

  • Using the bound() method

  • Using the lowerBound() method

  • Using the upperBound() method

Using the only method

This method takes a single key as its argument and creates a KeyRange object that represents a range that only includes that key.
