devkit-logging v1.0.0

Useful logger!

Example Logger Usage

var logging = require('devkit-logging');

var logger = logging.get('test');

logging.setDefaultLevel('silly');

var arr = [4, 67, 8, 9];
logger.silly('an array?', arr);

var obj = {
  x: 3,
  y: 7,
  data: {
    beep: 'boop'
  }
};
logger.debug('an object?', obj);

for (var i = 0; i < 3; i++) {
  logger.info('hello world!', i);
}

logger.warn('hello world!');

var err = new Error('Some error');
logger.error('oh no!', err);

Example Trace Usage

Notes

A global trace(...) function is exposed, and can be used to filter out particularly verbose development logs. Trace uses environment variables by default, but can also be invoked programatically.

DEVKIT_TRACE {Boolean}

• Whether or not to show trace logs

DEVKIT_TRACE_NAMES {String}

• Comma separated list of paths to show traces for.
• If no names are specified, traces for all paths will be shown.

Usage

With environment variables:

Start app with environment variables set

DEVKIT_TRACE=true DEVKIT_TRACE_NAMES=index.js,someFolder node src/index.js

Without environment variables:

// NOTE: Must require logging before trying to call trace()
var logging = require('devkit-logging');

logging.setTraceEnabled(true);

trace('something');
