Vaadin Libraries

This section documents Flowing Code's open source libraries that are tightly related to Vaadin but are not Vaadin add-ons themselves. They provide tooling and utilities for Vaadin projects.

  • JSON Migration Helper — a compatibility layer that lets the same code work across Vaadin 14, 23, 24, and 25 by abstracting away the JSON-handling changes introduced in Vaadin 25.
  • RPC for Vaadin TestBench — a Server-Side RPC mechanism for use from Vaadin TestBench integration tests, with support for RMI-style remote object invocation and side-channel calls.

Both libraries are distributed under Apache License 2.0 and developed in the Flowing Code GitHub organization.
