MongoDB driver warning

Node
1

Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
(Use node --trace-warnings ... to show where the warning was created)

My code in db.js

const mongoose = require(‘mongoose’);
const winston = require(‘winston’);
const config = require(‘config’);

module.exports = function() {
const db = config.get(‘db’);
mongoose.connect(db, { useNewUrlParser: true, useUnifiedTopology: true })
.then(() => winston.info(Connected to ${db}...));
}

My code in logging.js

const winston = require(‘winston’);
require(‘winston-mongodb’);
require(‘express-async-errors’);
const config = require(‘config’);

module.exports = function() {
winston.exceptions.handle(
new winston.transports.Console({ colorize: true, prettyPrint: true }),
new winston.transports.File({filename: ‘uncaughtExceptions.log’})
);

process.on('unhandledRejection', (ex) => {
    throw ex;
});

winston.add(
    new winston.transports.MongoDB({
      db: 'mongodb://localhost/vidly',
      level: 'error',
      options: { useUnifiedTopology: true },
    })
  );    
winston.add(new winston.transports.File({filename: 'logfile.log'}));
winston.add(new winston.transports.MongoDB({
    db: 'mongodb://localhost/vidly',
    level: 'info'
}));

}

Please note I am using mongoose and not MongoClient anywhere

2 
winston.info(Connected to ${db}...));

should be

winston.info(`Connected to ${db}...`));
3

it is:
winston.info(Connected to ${db}...));

it is just not showing in here

what version of Winston you’re using? is it the latest?

5

if you’ve reading the documentation of the latest Winston. The recommended way to use winston is to create your own logger. The simplest way to do this is using winston.createLogger

6

Ok, and after creating the logger can you please help me with the next steps?

here is how I define my logger

const { createLogger, format, transports } = require("winston");
const { combine, timestamp, printf, simple } = format;
// require("winston-mongodb");

const logFormat = printf(({ level, message, timestamp }) => {
  return `${level}: ${timestamp} ${message}`;
});

const logger = createLogger({
  transports: [
    new transports.Console({
      level: "debug",
      handleExceptions: true,
      handleRejections: true,
      format: simple(),
    }),
    new transports.File({
      level: "info",
      filename: "loginfo.log",
      format: simple(),
    }),
    new transports.File({
      level: "error",
      filename: "exception.log",
      handleExceptions: true,
      handleRejections: true,
      format: combine(timestamp({ format: "DD/MM/YYYY HH:mm:ss" }), logFormat),
    }),
  ],
});

module.exports = logger;
module.exports.stream = {
  write: function (message) {
    logger.info(message.replace(/(\r\n|\n|\r)/gm, ""));
  },
};
