A logger with a horrible name
This is a logger that is used for creating prod-ready message and performance logs for an app consisting of microservices. It outputs logs in a way that allows for easy graylog parsing using extractors
npm i --save flow-logger
import Logger from 'flow-logger';
const logger = new Logger({ name: 'microservice-1', persistentId: message.flowId, version: '1.2.3'});
logger.message('Hi!');
...
logger.message(Buffer.from('1'));
...
const e = new Error('bla');
e.stack = 'at Bla';
logger.error(e);
...
logger.toString();
