minimal-logger

A minimal logger for Node and React Native

Features:

• Provides a default logger and a way to get named loggers.
• Works the same way as console.<debug | error | info | log | trace | warn>.
• Supports turning individual logger on or off.
• No messing up with line numbers.
• No dependencies.

Usage

Install:

yarn add minimal-logger

Default logger:

import logger from 'minimal-logger';

logger.warn('something went wrong.');

Named logger:

import { getLogger } from 'minimal-logger';

getLogger('foo').warn('something went wrong.');

Enable and disable logger:

import { getLogger } from 'minimal-logger';

logger = getLogger('foo');
logger.warn('something went wrong.');
logger.setEnabled(false);
logger.warn('this line will be muted.');

Notes

• Loggers will be disabled by default if __DEV__ is false or NODE_ENV is not dev or development.
• Multiple calls to getLogger() with the same name will always return a reference to the same Logger object. Therefore if you disable it in one file, it will disable all references to the same Logger.
