Expand description

ServerMessage defines the message types that servers can send.

Variants

ConnectionError

Fields

payload: ConnectionErrorPayload

The error that occurred.

ConnectionError is used for errors that are not associated with a GraphQL operation. For example, this will be used when:

  • The server is unable to parse a client’s message.
  • The client’s initialization parameters are rejected.

ConnectionAck

ConnectionAck is sent in response to a client’s ConnectionInit message if the server accepted a connection.

Data

Fields

id: String

The id of the operation that the data is for.

payload: DataPayload<S>

The data and errors that occurred during execution.

Data contains the result of a query, mutation, or subscription event.

Error

Fields

id: String

The id of the operation that triggered this error.

payload: ErrorPayload

The error(s).

Error contains an error that occurs before execution, such as validation errors.

Complete

Fields

id: String

The id of the operation that has completed.

Complete indicates that no more data will be sent for the given operation.

ConnectionKeepAlive

ConnectionKeepAlive is sent periodically after accepting a connection.
