Stream Board game state

Stream the state of a game being played with the Board API, as ndjson.

Use this endpoint to get updates about the game in real-time, with a single request.

Each line is a JSON object containing a type field. Possible values are:

• gameFull Full game data. All values are immutable, except for the state field.
• gameState Current state of the game. Immutable values not included. Sent when a move is played, a draw is offered, or when the game ends.
• chatLine Chat message sent by a user in the room "player" or "spectator".
• opponentGone Whether the opponent has left the game, and how long before you can claim a win or draw.

The first line is always of type gameFull.

The server closes the stream when the game ends, or if the game has already ended.
