How to get logs of NodeJs application running in forever npm?

Question

I was wondering, is there any way I can check out the logs of the my nodejs server when I've forever'd it using forever start server.js to look at what's being logged, check any live errors and such.

I looked at their documentation but couldn't find anything related to this. I want to be able to look at the console.

Answer 1

First find out where your logs are stored using:

sudo forever list

for each process you can see something like this as logfile:

/root/.forever/_Jht.log

use 'tail -f' to monitor its changes:

sudo tail -f /root/.forever/_Jht.log

You can also set your desired path for log files, see this:

Answer 2

As forever start an application on background it gets hard to access old logs. If you can use a library for maintaining logs, I will suggest simple-node-logger . Using this library you can save all your logs on a file and can access that file any time using:

tail -f logsFile.txt

Using this command this will keep printing new changes over logsFile.txt as logger keep updating logs. This will help you to maintain all the logs for you.
