The NodeCore CommandLine can access an instance of NodeCore

Commands: Not Connected

When first started, the command line is not connected.

connect

Connects to an instance of nodecore via gRPC, on port 10500.

If connected to a node, then many other commands are available.

Syntax: 

connect <peer>

Examples: 

#connect to an instance
connect 77.46.106.162:10500

help

Standard help command.

Syntax: 

help [command]

Examples: 

#returns list of available commands
help

#returns info for a specific command
help connect

quit

Standard quit command, exits the console

Commands: Connected

Once the CLI is connected to a NodeCore instance, then there are many other commands that can be run.


addnode

Add a peer node to the local configuration and connect. After adding a node, you should see it when running getpeerinfo,

Syntax 

addnode <peer>

Example 

# input
addnode 93.130.33.180:6500

#output (also run getpeerinfo to see the node added)
rpc (127.0.0.1:10500) > {
  "payload": {},
  "success": true,
  "messages": []
}

disconnect

Simply disconnects from the current NodeCore instance
