NODLOG

Node wrapper for logging to:

• console
• logmatic

It has several logging levels:

• trace [5]: debug information to have a basic stack trace
• debug [4]: information used for debug
• info [3]: notification of a normal action
• warn [2]: incorrect behavior but the application can continue
• error [1]: exceptions
• fatal [0]: problem that prevents the service from running correctly

It can be used just like console.log() with multiple parameters and objects.

Installation

npm install --save nodlog

How to use

var log = require('nodlog')({
 console: {
   level: 5,
   timestamp: true
 },
 logmatic: {
   key: 'API_KEY',
   enabled: true,
   context: {
     app: 'myApp',
     instance: 'dev-1',
     env: 'development'
   },
   level: 3,
   label: 'dev-1'
 },
});
 
log.info('Informative note');
log.warn('The object', myObject, 'is invalid');

Timers

Named timers can be used to check how long a function call takes:

log.startTimer('test');
setTimeout(function () {
  log.stopTimer('test');
}, 300);

Will log as trace if options.timers is true :

Timer "test" took 301 ms, { timer: "test", ms: 301 }
