The possible parameters to execute server.js are:

• [-p, --port] port where the server will listen to
• [--insecure] allows session cookies to be passed around in insecure connections

• [-d, --daemon] start the server as a daemon

Possible errors

• The main problems verified are relationed to the database connection. In case of errors, verify if is possible do the connection with database by psqlcommand (in the same user that is in configuration file).

• Another commum case is to try execute the service in a port that another process is alredy executing. In this case a error similar to Error: bind EADDRINUSE null:3000 will be notified. In this case, try alter the port that the service is provided or stop the other process.
