OptionaloncloseCallback for when the connection is closed for any reason.
This should be invoked when close() is called as well.
OptionalonerrorCallback for when an error occurs.
Note that errors are not necessarily fatal; they are used for reporting any kind of exceptional condition out of band.
OptionalonmessageThe child process pid spawned by this transport.
This is only available after the transport has been started.
The stderr stream of the child process, if StdioServerParameters.stderr was set to "pipe" or "overlapped".
If stderr piping was requested, a PassThrough stream is returned immediately, allowing callers to
attach listeners before the start method is invoked. This prevents loss of any early
error output emitted by the child process.
Closes the connection.
Sends a JSON-RPC message (request or response).
If present, relatedRequestId is used to indicate to the transport which incoming request to associate this outgoing message with.
Starts the server process and prepares to communicate with it.
Client transport for stdio: this will connect to a server by spawning a process and communicating with it over stdin/stdout.
This transport is only available in Node.js environments.
