Service objects

The functions return service objects containing the following fields:

• name: the service name
• description: the optional service description, may not be present
• state: an integer state code with the following possible values
  • 1: STOPPED

  • 7: PAUSED

• pid: the process identifier for the service, if it is running

Query all services

queryServices asynchronously returns an array of service objects, for all services installed on the system.

Parameters:

• callback: a callback function function(error, service):
  • error: error that occured or null if no error
  • service: an array of service objects for all installed services.

Example:

var serviceManager = require('./windows-service-manager');

serviceManager.queryServices(function(error, services) {
    console.log(error || services);
});

Query a single service

queryService asynchronously returns an service object for the service with the specified name.

Parameters:

• name: the name of the service to query.
• callback: a callback function function(error, service):
  • error: error that occured or null if no error
  • service: a service object for the service named name.

Example:

var serviceManager = require('./windows-service-manager');

serviceManager.queryService('puppet' ,function(error, services) {
    console.log(error || services);
});

Start a service

startService asynchronously starts a service with the specified name. If the service is already started, no error is returned.

Parameters:

• name: the name of the service to start.
• timeoutSeconds: number of seconds to poll before returning. If 0, no polling is done. If a non-zero value, service status is polled. If the service has not started before the timeout expires, the callback error will be the string 'timeout'.
• callback: a callback function function(error, service):
  • error: error that occured or null if no error
  • service: a service object for the service named name.

Example:

var serviceManager = require('./windows-service-manager');

serviceManager.startService('puppet', 5, function(error, services) {
    console.log(error || services);
});

Stop a service

stopService asynchronously stops a service with the specified name. If the service is already stopped, no error is returned.

Parameters:

• name: the name of the service to stop.
• timeoutSeconds: number of seconds to poll before returning. If 0, no polling is done. If a non-zero value, service status is polled. If the service has not stopped before the timeout expires, the callback error will be the string 'timeout'.
• forceKill: boolean that specifies whether the service process should be killed if the service has not stopped within a non zero timeout interval.
• callback: a callback function function(error, service):
  • error: error that occured or null if no error
  • service: a service object for the service named name.

Example:

var serviceManager = require('./windows-service-manager');

serviceManager.stopService('puppet', 20, true, function(error, services) {
    console.log(error || services);
});
