fm-log

What?

Straight-forward logging module.

• lines up everything in nice columns

• uses colors

• sends everything straight to console.log, no events, no nextTick()

• condenses repeated messages like:

    2014-04-24 17:17:00.138 [DEBUG ] (    api-mobile.js) Cleaning up messages...
    2014-04-24 17:34:32.715 [DEBUG ] (    api-mobile.js) Last message repeated 17 times.
    2014-04-24 17:34:32.715 [INFO  ] (    api-person.js) API-REQUEST: List Person...
  

• displays stack traces for logged Error instances and other multi-line content like:

  

Example

var log = require( "fm-log" ).module( path.basename( __filename ) );
log.info( "Initializing application..." );
  
log.debug( "We be logging" );
log.info( "We be logging" );
log.notice( "We be logging" );
log.warn( "We be warning" );
log.error( "We be logging" );
log.critical( "We be logging" );

var generic = require( "fm-log" );
generic.notice( "We don't need no prefix" );

How?

Put this in every file where you want to log:

var log = require( "fm-log" ).module( path.basename( __filename ) );

Then just use log.info or one of the other logging levels shown above.

For loggers without a specific prefix, just require() the module and use it directly:

var generic = require( "fm-log" );
generic.notice( "We don't need no prefix" );
