🧪 Step 1: Test Your Deployed Worker

Before touching your existing code, verify the core logic works using command line tools.

1. Create a Session (Simulate Plover Plugin):

curl -s -X POST "$WORKER_URL/session/initiate" | tee session.json | jq

Expected Response: A JSON object with a protocol, sessionId, tabletConnectionToken and pcConnectionToken.

{
  "protocol": "wss",
  "sessionId": "d7733ec2-248c-4574-bd68-875304d6f1db",
  "tabletConnectionToken": "c836995d4d9fdcb06bc298d2ccb4b6979758c177a5fa9c34b7477d23bcb27a56",
  "pcConnectionToken": "2c5e1e9449a1f15101361ed6d32af1562c26093c2d3843a97833eb0647c11151"
}

2. Connect as the PC (Simulate Plugin WebSocket): Use a WebSocket client like wscat to connect as the PC.

# Construct the PC connection URL from the sessionId in the previous response
wscat -c "`jq -r .protocol session.json`//${BASE_WORKER_URL}/session/`jq -r .sessionId session.json`/connect?token=`jq -r .pcConnectionToken session.json`"

You should see a successful connection. The Worker logs will show PC connected to session.

Upon connecting, the PC client will receive a welcome message with its unique session ID: {"id":0,"type":"system","message":"Connection established","clientType":"pc"}

3. Connect as the Tablet (Simulate React App): In a second terminal, use the exact tabletConnectionUrl from Step 1.

wscat -c "`jq -r .protocol session.json`//${BASE_WORKER_URL}/session/`jq -r .sessionId session.json`/join?token=`jq -r .tabletConnectionToken session.json`"

Expected Results:

The tablet terminal will connect and receive its own welcome message with a unique ID: {"id":1,"type":"system","message":"Connection established","clientType":"tablet"}

The PC terminal will automatically receive a notification that a new tablet has joined. This message includes the new tablet's ID and, crucially, a new newTabletToken. This new token must be used to connect any subsequent tablets, as the original tabletConnectionToken is now invalid.

{
  "clientType":"tablet",
  "id":1,
  "type":"tablet_connected",
  "newTabletToken":"22b93a639b1eb0d5bf3f713d30c54841fe8a26fdf8a71c037d8cde13d9543424",
  "timestamp":1764964194099
}

🧪 Step 2: Test Message Relay & Close

With both clients connected, you can test the new private and public messaging system.

1. Send a Public Message from Tablet to PC: In the tablet's terminal, send a message to all clients of type pc. The PC client (ID 0) will receive it, complete with the sender's information.

# In the tablet's wscat session:
{"to":{"type":"pc"},"payload":{"stroke":"KAT"}}

The PC terminal will receive: {'payload': {'stroke': 'KAT'}, 'from': {'id': 0, 'type': 'tablet'}}

2. Send a Private Message from PC to Tablet: In the PC's terminal, send a private message specifically to the tablet with ID 1.

# In the PC's wscat session:
{"to":{"type":"tablet","id":1},"payload":{"message":"Hello from PC!"}}

The tablet terminal will receive: {'payload': {'message':'Hello from PC!'},'from':{'id':0,'type':'pc'}}

3. Get a List of Participants: From any client, send a get_participants command.

# In any wscat session:
{"payload":{"command":"get_participants"}}

The client that sent the request will receive a list of all connected clients. For example:

{"type":"participants_list","participants":[{"id":0,"type":"pc"},{"id":1,"type":"tablet"}]}

4. Close the Session: Send a close command from any connected client. This will terminate the entire session for all participants.

# In any wscat session:
{"payload":{"command":"close"}}

Both WebSocket connections should close immediately.
