How to use Winston in several modules?

Question

I have several modules - let\'s say server.js, module1.js,...,moduleN.js.

I would like define the log file in my server.js:

winston.add(winston.trans         


        

Answer 1

Just create logger.js and put

const winston = require('winston');

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.combine(
    winston.format.colorize(),
    winston.format.simple()
  ),
  transports: [
    new winston.transports.Console()
  ]
});

module.exports = logger

Then you can require and use it anywhere, since logger is now singleton.

const logger = require('./utils/logger');
logger.info('Hello!');

This even gives you an option to swap logging library if needed. The accepted answer is totally wrong and one step closer to spaghetti code.
