List of string arguments passed to the Node.js executable.

File path to worker file.

String arguments passed to worker.

Whether or not to send output to parent's stdio.

Configures the stdio of forked processes. Because the cluster module relies on IPC to function, this configuration must contain an 'ipc' entry. When this option is provided, it overrides silent. See child_prcess.spawn()'s stdio.

Sets the user identity of the process. (See setuid(2).)

Sets the group identity of the process. (See setgid(2).)

Sets inspector port of worker. This can be a number, or a function that takes no arguments and returns a number. By default each worker gets its own port, incremented from the primary's process.debugPort.

Specify the kind of serialization used for sending messages between processes. Possible values are 'json' and 'advanced'. See Advanced serialization for child_process for more details.

Current working directory of the worker process.

Hide the forked processes console window that would normally be created on Windows systems.
