node js colourful logging framework
require sexylog in your nodejs app entry file (usually app.js) like so:
require('sexylog');
This makes the logger object available (yes, globally) anywhere in your code, like so:
(1) logger.trace("running logging test");
(2) logger.debug("running logging test");
(3) logger.info("running logging test");
(4) logger.warn("running logging test");
(5) logger.error("running logging test");
currently sexylog is set via an environment variable named LEVEL at the command line.
NOTE: Logging levels are show in order of priority. If you set the variable to TRACE all log levels above this level will print out. If you set the log level to WARN, only WARN and ERROR message will be printed, but nothing below these levels will print out.
Example:
export LOG_LEVEL=info
or
LOG_LEVEL=trace node app.js
mocha test/logging-test.js
