winston-fast-rabbitmq

A RabbitMQ transport for Winston.

It closes the connection after every message, but keeps the connection open as long as new messages arrive within a short timespan.

• Easy to use and fast to implement
• Build using amqplib
• Non-blocking as it uses rabbit-chatter

Usage

Use npm to install the module:

	npm install winston-fast-rabbitmq

Then use require() to load it in your code:

	var winstonFastRabbitMq = require('winston-fast-rabbitmq');

Setup the transport in winston:

	winston.add(winstonFastRabbitMq, options);

Now you are ready to send some logs to RabbitMq!

Options

Most options are passed on directly to rabbit-chatter. So have a look at that module to see the rest of the option list.

level

String

Default: 'info'

Sets the minimum required level for sending the log to RabbitMQ. You can find the levels here.

formatter

function

Default: See below

Sets the standard formatter for the message. If no function is passed in this option, it will use the default-formatter which looks like this:

For versions: <=1.2.4

function(level, meta, message)
{
    return JSON.stringify({ level: level, meta: meta, message: message  });
};

For versions: >1.2.4

function(options)
{
    return JSON.stringify({ level: options.level, meta: options.meta, message: options.message  });
};

Thanks to Thomas from ebuildy for this contribution :-)

Tests

To run tests on this module, make sure that the modules for the tests are installed

	npm install winston-fast-rabbitmq --dev

Then run:

	npm test

NOTICE: The test is not only a unit test but also a functionality test. So RabbitMQ is required to be installed locally in order to run the test.
