instance.error(new Error('Logs error with the stack'))

Nested

ausgabe supports nested logger instances.

import { createLogger } from 'ausgabe'

const instance = createLogger({
	requests: createLogger({

			badge: '↗',
			label: 'get',
		},
		post: {

		},
	}),
})

instance.requests.get('http://example.com')
instance.requests.post('http://example.com')

Streams

ausgabe streams to process.stdout by default, but also allows custom writable streams.

import { Writable } from 'node:stream'
import { createLogger } from 'ausgabe'

const stream = new Writable({
	write: (chunk, encoding, callback) => {
		console.log(chunk.toString())
		callback()
	},
})

const instance = createLogger({
	info: {
		color: 'blue',
		badge: 'ℹ',
		label: 'info',
		streams: [stream],
	},
})
