is this repo still working?

[nort3x]

as grafana stated in their official website their api can undergo breaking changes,
and they didn't even listed this project even as an unofficial related library to their project

i hoped i could use this lib (which is currently most popular node lib related to loki) to use it's functionality but i struggled for +8 hours and couldn't make it work,

it's not failing fast i can't even tell if it's facing any issue or not, tried different configurations then used the provided example and tests and yet i can't get what i need

I'm currently in the same boat, having the same kind of results. Hard to tell if the logs are even hitting the API. I've downloaded and run directly from the latest code to try and figure it out.

Okay I think I sorted my problem - it was TLS related but there was no way to easily figure that out.

[nort3x]

the docker provided in example also is pulling latest loki and the example doesn't work with that , at least for a temporary solution we need to know which version it has been tested with

it's good piece of work and need more attention towards it <3

Could you maybe try with a fixed version of loki (instead of latest)? That would help clarify what is working and what not.
I ran the examples with latest and 2.4.1, and they both work for me.

The problem is that Winston returns the timestamp as a string and this transport expects a date. As a workaround I set the option replaceTimestamp to true.

winston-loki/index.js

Lines 55 to 84 in 8af9b48

	const { label, labels, timestamp, level, message, ...rest } = info
	// build custom labels if provided
	let lokiLabels = { level: level }
	lokiLabels = Object.assign(lokiLabels, labels)
	if (this.labels) {
	lokiLabels = Object.assign(lokiLabels, this.labels)
	} else {
	lokiLabels['job'] = label
	}
	// follow the format provided
	const line = this.useCustomFormat ? info[MESSAGE] : `${message} ${
	rest && Object.keys(rest).length > 0 ? JSON.stringify(rest) : ''
	}`
	// Make sure all label values are strings
	lokiLabels = Object.fromEntries(Object.entries(lokiLabels).map(([key, value]) => [key, value ? value.toString() : value]))
	// Construct the log to fit Grafana Loki's accepted format
	const logEntry = {
	labels: lokiLabels,
	entries: [
	{
	ts: timestamp || Date.now().valueOf(),
	line
	}
	]
	}

I use the latest for Loki, Grafana, and Promtail and it's working fine. Please consider that URL for Loki on Grafana must be http://loki:3100 and for winston-loki must be http://localhost:3100

i see some contradictory comments here, let me test it with current main head at
b825d3b

and i will report the results

That was my issue, thank you.
