Class Logger

Logger

This wraps the Debug object from npm 'Debug' package to provide "log-levels". The log-levels are handled as top-level namespaces.

Examples

export DEBUG="error:*" -> Log 'error' messages from every module
export DEBUG="error:moduleA" -> Log 'error' messages for moduleA only
export DEBUG="error:*, warn:*, info:*, debug:*" -> Log everything

See https://www.npmjs.com/package/debug for more information on configuration.

When instantiated for a given "moduleName", this object provides an error() function that logs with amended name "error:moduleName". Likewise for warn(), info(), and debug().
