-2. [`simple-client`](samples/simple-client) - an OPC UA client that connects to a server and subscribes to the values of v1, v2, v3 and v4.

 3. [`discovery-client`](lib/examples/discovery-client) - an OPC UA client that connects to a discovery server and lists the servers registered on it.
 4. [`chess-server`](samples/chess-server) - an OPC UA server that connects to a chess engine as its back end and updates variables representing the state of the game.
 5. [`demo-server`](samples/demo-server) - an OPC UA server that is more complex than the simple server and can be used for compliance testing.

 The client connects to the server, creates a subscription to variables v1,
