Inconsistent string interpolation

[magixx]

I'm sure this is likely an issue with the way I've set things up (latest node, bable, webpack, ) but I cannot get string interpolation to work when using Logger.get. ex:

import Logger from 'js-logger'

Logger.useDefaults()
Logger.warn('TEST')
Logger.warn('TEST %sPOLATED', 'INTER')
const log = Logger.get('Log')
log.warn('Test')
log.warn('TEST %sPOLATED', 'INTER')

Will output:

TEST
TEST INTERPOLATED
[Log] Test
[Log] TEST %sPOLATED INTER

So what am I not understanding here?

In addition, if I do not use Logger.useDefaults(), for example by replacing that line with Logger.setLevel(Logger.INFO), I won't see any logs at all. Any thoughts as to why this occurs?

Hi @magixx, sorry for the slow response.

Yep, the broken string interpolation is indeed a bug caused by the default log message formatter which will unshift a named Logger's name into the messages array; as you may be aware, console.log() and friends will only perform interpolation on first value.
