footprint-node v1.1.0

Footprint - Node Logger

A simple and small logger for node.js implemented in ES6 using Winston.

Installation

npm install footprint-node

Usage

Simply require the logger in any file you like:

const Logger = require('footprint-node');

You can now log any message by calling the .log(level, message) method. For example:

Logger.log('info', 'Process started...');

As an alternative to specify the log level as a string the library supports utility methods for all default log levels:

Logger.error('Some message that will be logged with the ERROR level.');
Logger.warn('Some message that will be logged with the WARN level.');
Logger.info('Some message that will be logged with the INFO level.');
Logger.verbose('Some message that will be logged with the VERBOSE level.');
Logger.debug('Some message that will be logged with the DEBUG level.');
Logger.silly('Some message that will be logged with the SILLY level.');

Configuration

The logger is configured using node environment variables.

Log Level

export LOGGER_LEVEL=...

Default: info

Specify the log level the logger should use. This can be set to any of the following values:

• error (highest priority)
• warn
• info
• verbose
• debug
• silly (lowest priority)

The higher the priority the more important the message is considered to be, and the lower the corresponding integer priority.

Handle Exceptions

export LOGGER_HANDLE_EXCEPTIONS=...

Default: true

Determines whether the logger should handle uncaught exceptions or not. If set to true the logger will catch and log any uncaught exceptions.
