Clients connect to server defined address using websocket.
Each client robot sends its own metadata.
All server logs are saved locally in the serverLogs directory.
Robot Meta-data format
// USE THE SAME NAMING CONVENTION
// robotName is the robot pysical machine name
// robotAddress is its mac-address to be used as unique identifier
// userID is the id of the user the robot gets after authentication
{
"robotName": "LAPTOP-TAUNF8FD",
"robotAddress": "001AFFDB45C2",
"userID": 4
}At job triggering, information regarding robot, package and their schedule must be stated.
The package is validated for any missing data, then saved locally in the packages Directory.
New job instance is created and scheduled for the provided date and time.
