# GraphQL-WS Proof of Concept

This is a simple test script to verify we can send messages to Kosmi using the WebSocket GraphQL API directly, following the `graphql-ws` protocol.

## What This Tests

1. Connects to Kosmi's WebSocket endpoint (`wss://engine.kosmi.io/gql-ws`)
2. Follows the graphql-ws protocol:
   - Sends `connection_init`
   - Waits for `connection_ack`
   - Sends a mutation using `subscribe` message type
3. Attempts to send "Hello World from GraphQL-WS! 🎉" to the chat

## Protocol Details

Kosmi uses the [graphql-ws protocol](https://github.com/enisdenjo/graphql-ws/blob/master/PROTOCOL.md), which is different from the older `subscriptions-transport-ws`.

Key differences:
- Uses `graphql-transport-ws` subprotocol
- Both queries/mutations AND subscriptions use `type: "subscribe"`
- Must send `connection_init` before any operations

## Running the Test

```bash
# From the project root
go run cmd/test-graphql-ws/main.go
```

## Expected Behavior

If successful, you should see:
1. ✅ WebSocket connected
2. ✅ Connection acknowledged by server
3. ✅ Message sent
4. 📨 Response from server (either success or error)

## What We're Testing

This will help us determine if:
- We can connect to Kosmi's WebSocket without browser automation
- The authentication works (or what auth is needed)
- We can send messages via GraphQL mutations over WebSocket
- We can replace the UI automation approach with direct WebSocket

## Notes

- Change `roomID` in the code to match your Kosmi room
- The script will keep running until you press Ctrl+C
- All messages are logged for debugging
