Code taken from flow
function log_data(message,node,flow) {
let d = new Date();
let now = d.getTime();
let logs = global.get("logs") || [];
let temp = {};
temp.timestamp = now;
temp.utctime = d.toLocaleString();
temp.flow = flow;
temp.node = node;
temp.message = message;
logs.push(temp);
global.set("logs", logs);
}
global.set("log_data",log_data);

//to use import it into the function node using
//let log_data=global.get("log_data");
//call it anywhere in the function using
//log_data(message, node, flow);
