Woodman

Woodman is a JavaScript logger utility for Web applications and Node.js applications. Woodman is roughly as simple to use as the console, only much more powerful. Woodman lets you take precise control over what gets logged where and how... and knows how to disappear from production code if needed.

// Using Woodman                            // Using the console
woodman.load('console');
var logger = woodman.getLogger('myapp');
logger.log('Hello Woodman');                console.log('Hello Woodman');
logger.warn('This is a warning');           console.warn('This is a warning');
logger.error('This is an error');           console.error('This is an error');

Woodman features:

• message levels similar to those exposed by the console object (log, info, warn, error). Through configuration, messages may be filtered based on their level.
• a logger hierarchy to keep track of the origin of messages and disable some of them based on their origin.
• appenders to change the destination where messages are sent without changing the code. Messages can be sent to multiple destinations at once. Examples of appenders include the console, a log file or a remote server using Web sockets. New appenders can easily be created.
• layouts to specify the format and structure of the messages sent to an appender: raw string, CSV, JSON, XML, whatever. New layouts can easily be created.
• filters to disable messages based on something else than their level or origin.
• a removal tool that drops all traces of Woodman from your code to create a shipping version of your app without logs. With Woodman, no more console.log in your production code! See Precompilation for details.

Wherever applicable, Woodman follows the architecture, terminology and API of the Apache Log4j 2 project.
