How to Log in SailsJS

Question

What is the actual syntax to log in SailsJS?

Docs don't have anything, but found the following line in the site's roadmap

"Pull out Sails.log (winston wrapper) as a separate module so it can be used by waterline"

I image it's something like:

Sails.log(...)
Sails.error(...)
Sails.warn(...)

In your controllers, models, services, and anywhere else that the sails global is available, you can log with one of:

sails.log();
sails.log.warn();
sails.log.info();
sails.log.debug();
sails.log.error();
sails.log.verbose();
sails.log.silly();

The logging level (that is, the level at which logs will be output to the console) is set in /config/log.js.

Also remember that you need to set which level to log, or use a command line parameter (like --verbose). – Diego Pamio May 17 '14 at 00:55

To extend on the Scott Answer, dont forget to add the filePath: property to log.js file... otherwise it will not work :)

So it should be something like:

log: {
level: 'info',
maxSize: 1000,
filePath: 'c://serverlogs/mylogfilename.log'

Answer is changed based on Joseph question.

Which location the log file is created? I tried filePath: '~/name.log'; filePath: 'name.log'. But the files are not created though I can see the log messages in the console. I'm using 0.10.0-rc5. – jjude May 20 '14 at 01:46

@Joseph please take a look at the previous answer. I have updated it. Hope it helps. – Amiga500 May 20 '14 at 08:17
Mine is not created too even specifying filePath. My sails version is 0.10.0-rc7 – A-letubby Aug 25 '14 at 05:50
I found the solution. The filePath only worked for under 0.10. For >0.9, please see https://stackoverflow.com/questions/25211183/sails-js-0-10-x-log-to-file – A-letubby Aug 25 '14 at 06:45
