Winston transport for @Sentry/node

Usage no npm install needed!

<script type="module">
  import winstonSentryLog from '';



Sentry transport for the winston v3 logger using @sentry/node.



yarn add winston winston-sentry-log


You can configure winston-sentry-log in two different ways.

With winston.createLogger:

import winston from 'winston';
import Sentry from 'winston-sentry-log';

const options = {
  config: {
    dsn: "https://******"
  level: "info"

const logger = winston.createLogger({
  transports: [new Sentry(options)]

Or with winston's add method:

import winston from 'winston';
import Sentry from 'winston-sentry-log';

const logger = winston.createLogger();

logger.add(Sentry, options);

See Options below for custom configuration.

Log Level Mapping

Winston logging levels are mapped by default to Sentry's acceptable levels.

These defaults are set as options.levelsMap and are:

  silly: 'debug',
  verbose: 'debug',
  info: 'info',
  debug: 'debug',
  warn: 'warning',
  error: 'error'

You can customize how log levels are mapped using the levelsMap option:

new Sentry({
  levelsMap: {
    verbose: "info"

If no log level mapping was found for the given level passed, then it will not log anything.
