rhinologger v0.2.2

Rhino Logger

RhinoLogger is an opinionated, uncomplicated logging library for JavaScript.

You initialize the constructor with the log level you want to log at. Anything at or below that level will be logged, with lower levels being more serious.

import { RhinoLogger } from 'rhinologger`
const logger = new RhinoLogger(RhinoLogger.WARNING)
logger.log(RhinoLogger.INFO, 'myapp.testsource', {msg: 'I will get ignored'})
logger.log(RhinoLogger.WARNING, 'myapp.testsource', {msg: 'I will get logged'})
logger.setLevel(RhinoLogger.DEBUG)
logger.log(RhinoLogger.DEBUG, 'myapp.testsource', {msg: 'I will get logged'})

Alternatively, you can use the default logger which is set to the debug level at the time of package initialization, but you can update it later.

import { logger } from 'rhinologger'
logger.log(RhinoLogger.INFO, 'myapp.testsource', {msg: 'I will get logged'})

Log levels of WARNING and above will be logged via console.log, while log levels below WARNING (ERROR and below) will be logged via console.error.

The output is designed for easy parsing by both machine and humans. It's a minified JSON with the following fields:

• timestamp - a human readable timestamp when the log was generated
• unixtime - a Unix timestamp when the log was generated
• level - the log level
• source - the source of the log message
• payload - the log message
