Minimal lightweight (0.9KB minified and gzipped) plugin for loglevel message prefixing
1npm install loglevel-prefix --save
1prefix(log[, options]);
log - root logger, imported from loglevel package
options - configuration object
1default_options = { 2 template: '[%t] %l:', 3 timestampFormatter: date => date.toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, '$1'), 4 levelFormatter: level => level.toUpperCase(), 5 nameFormatter: name => name || 'root' 6}
Plugin formats the prefix using template option as a printf-like format.
The template is a string containing zero or more placeholder tokens. Each placeholder token is replaced with the value from loglevel messages parameters. Supported placeholders are:
%t - Timestamp of message.
%l - Level of message.
%n - Name of logger.
The timestampFormatter, levelFormatter and nameFormatter is a functions for formatting corresponding values
