flog

flog is a light-weight configurable front-end logger that is compatible with CJS, AMD and script loading. It can be used with node.js as well, but there are probably more complete solutions such as Winston; Tested in IE8, IE9, IE10, Chrome, Firefox, Safari, Opera

install

npm install flog or download flog.js

loading

flog can be loaded as:

• CJS module, which is useful if you use browserify or webmake or are using flog with node.js.
• AMD module with all AMD compatible loaders
• simple script tag adding flog to the global namespace

// CJS
flog = require('flog');

// AMD
require(['flog'], function (flog) {
})

// script
flog

setting the log level

By default, flog is set to be silent and doesn't output anything. To enable logging, you need to set the level:

flog.setLevel('info');

Possible values include:

• debug
• info
• warn
• error
• quiet
• all - alias for debug
• silent - alias for quiet

creating an instance

you can use the default flog object but you can also get instances set to different logging levels:

myFlog = flog.create();
myFlog.setLevel('error');
myFlog.info('Hello'); // doesn't output anything
myFlog.warn('Hello'); // doesn't output anything
myFlog.error('Hello'); // 'Hello'

logging methods

• flog.log()
• flog.info()
• flog.warn()
• flog.error()
