Getting started

yarn add @akronae/logger

If you set GRAFANA_*, logs will be sent to Grafana when NODE_ENV != development.
To write logs to a file, set LOG_DIR.

import { logger } from '@akronae/logger';

logger.info('crunched scrapper results', {
  client: 'acme',
  txCount: 122,
});

logger.error('uppps crash!', { error: new Error('ups') });

// not shown if you did not set
// LOG_LEVEL=debug
logger.debug({
  rnd: Math.random(),
  a: { b: 1, c: 'heyehey', d: [1, 2, { val: 'foo' }] },
});

logger.end();

How does it work

This packages provides a configured Winstonjs logger.
In development mode, it outputs prettified logs, with file lines and colored JSON.
In production mode, all this expensive stuff is removed, it only outputs a basic JSON format with Buffer/Error handling.
