raptor-logging

Super simple logging system that works on the server and and in the browser.

Example

projects/logging-test/run.js:

require('raptor-logging').configure({
    loggers: {
        'ROOT': 'WARN',
        'logging-test': 'DEBUG'
    }
});

// ...

var logger = require('raptor-logging').logger(module);
logger.debug('This is a debug message');

Output:

DEBUG logging-test/run: This is a debug message

You can also pass multiple arguments, as well as non-String arguments to the logging methods.

For example:

var logger = require('raptor-logging').logger(module);
logger.debug('This is a debug message', {foo: 'bar'});

Output:

DEBUG logging-test/run: This is a debug message { foo: 'bar' }

Installation

npm install raptor-logging --save

API

logger(module)

Returns a new Logger instance whose name is based on the filename associated with the Node.js module object.

Example:

var logger = require('raptor-logging').logger(module);
logger.debug('Hello World');

logger(name)

Returns a new Logger instance with the given name

Example:

var logger = require('raptor-logging').logger('foo');
logger.debug('Hello World');

Output:

DEBUG foo: Hello World

configure(options)

Supported options:

• loggers: A mapping of logger prefixes to log levels (see below)
• appenders: An array of appender instances (see ConsoleAppender for an example appender implementation)

Example:

require('raptor-logging').configure({
    'ROOT': 'WARN',
    'foo': 'DEBUG',
    'foo/bar': 'WARN',
});
