This logger binds console logging functions to produce log output with consistent code references in developer console.
It also supports log levels and a log hierarchy, such that you can control levels in the hierarchy.
A simple logger:
logger = require('js-logging')
logger.setLevel('debug')I developed this logger for atom packages and tests run in atom suite, so there is some specific support for this:
logger = require('js-logging')
# logger starts per default in logging only errors
logger.setSpecLevel('debug')
log.debug 'this message appears only in atom spec test mode'You have following logging functions:
logger = require('js-loggiing')
fooLogger = logger.getLogger('foo')
barLogger = logger.getLogger('foo.bar')
oneMoreBarLogger = fooLogger.getLogger('bar')
barLogger is oneMoreBarLogger # is true
fooLogger.setLevel('info')
barLogger.level # is also 'info' now
barLogger.setLevel 'silent' # no logging at all
logger.debug "debug message"
logger.trace "stack trace at this position"
logger.log "a log message"
logger.info "information"
logger.warn "warning"
logger.error "error"Log levels are configured as follows:
| level | value |
|---|---|
| silent | 0 |
| error | 1 |
| warn | 2 |
| info | 3 |
| log | 4 |
| trace | 5 |
| debug | 6 |
