[![NPM](https://img.shields.io/npm/v/@barchart/log4js-node-appenders)](https://www.npmjs.com/package/@barchart/log4js-node-appenders)

Assorted _appenders_ for use with the [log4js](https://github.com/log4js-node/log4js-node) library.

### Console Appender (for AWS Lambda)

A console appender that routes output to the correct function of the ```console``` object. This appender is useful for logging within an AWS Lambda function (avoids writing all logs at the ```INFO``` level).

* ```TRACE``` -> ```console.trace```

* ```DEBUG``` -> ```console.debug```

* ```INFO``` -> ```console.log```

* ```WARN``` -> ```console.warn```

* ```ERROR``` -> ```console.error```

* ```FATAL``` -> ```console.error```

**Usage Example**

```js

const log4js = require('log4js');

const appenders = require('@barchart/log4js-node-appenders');

log4js.configure({

	categories: {

		default: { appenders: [ 'lambda' ], level: 'trace' }

	},

	appenders: {

		lambda: {

			type: appenders.lambda,

			layout: {

				type: 'pattern',

				pattern: '%c - %m%'

			}

		}

	}

});

const logger = log4js.getLogger('Example');

logger.trace('Trace level log message');

logger.debug('Debug level log message');

logger.info('Info level log message');

logger.warn('Warn level log message');

logger.error('Error level log message');

logger.fatal('Fatal level log message');

```
