Better Stack Winston transport

Start logging in 3 steps

1. Install

Install Logtail Winston and Logtail Node NPM packages:

npm install @logtail/winston @logtail/node

2. Setup

Set up Logtail Winston transport:

const winston = require("winston");
const { Logtail } = require("@logtail/node");
const { LogtailTransport } = require("@logtail/winston");

// Create a Logtail client
const logtail = new Logtail("$SOURCE_TOKEN");

// Create a Winston logger - passing in the Logtail transport
const logger = winston.createLogger({
  transports: [new LogtailTransport(logtail)],
});

3. Start logging 🎉

Use Winston logger as usual:

logger.error("Something bad happened.");
logger.info("Log message with structured logging.", {
  item: "Orange Soda",
  price: 100.00
});

// Ensure that all logs are sent to Logtail
logtail.flush()

You should see your logs in Logtail -> Live tail.

Winston version 3.2.1 or higher is required.
