Query Parameters
Learn how to manage state with query parameters in a Vaadin application.
Query parameters are key-value pairs appended to the end of a URL after a ? character. Multiple parameters are separated by &.
For example, this URL: /orders?sort=date&filter=shipped
Contains the following query parameters:
-
sort→"date" -
filter→"shipped"
Query parameters are commonly used to store view-related state, such as a grid’s sort order or a search field’s value. Since they are optional, always provide default values when a parameter is missing.
