Import the logger from src/utils/logger.js. It is using the Winston logging library.
Logging should be done according to the following severity levels (ascending order from most important to least important):
const logger = require('<path to src>/utils/logger');
logger.error('message'); // level 0
logger.warn('message'); // level 1
logger.info('message'); // level 2
logger.http('message'); // level 3
logger.verbose('message'); // level 4
logger.info('message'); // level 5
