Namespaced Console Logger

Minimal namespaced stdout / stderr logger with a timestamp for the browser and Node.js.

The logger satisfies three requirements below and attempts to do nothing else:

1. Is small: has no dependencies & <50 loc (for the browser)
2. Has a timestamp
3. Has a namespace

Example output:

2015-08-10T20:09:20.526Z (namespace) INFO: Hello world!

Usage

import createLoggers from 'namespaced-console-logger';

const loggers = createLoggers();
const logger = loggers.get('namespace');

logger.info('Hello %s!', 'world');

• createLoggers() takes a minimum logging level, which is one of: ['info', 'warn', 'error'] and defaults to info. For example if you select warn, all info logs will be ignored. warn and error logs will be displayed.
