How do I fix my Discord bot being offline?

Question

I got recently interested in discord bots coding and I don't know what the problem is with this error, I tried different solutions I can find but all of them are not working and my bot is still offline on the server.

Error: Invalid transport, must be an object with a log method.

• this is the code i used that i found online.

  var Discord = require('discord.io');
  var logger = require('winston');
  var auth = require('./auth.json');
  // Configure logger settings
  logger.remove(logger.transports.Console);
  logger.add(logger.transports.Console, {
      colorize: true
  });
  logger.level = 'debug';
  // Initialize Discord Bot
  var bot = new Discord.Client({
     token: auth.token,
     autorun: true
  });
  bot.on('ready', function (evt) {
      logger.info('Connected');
      logger.info('Logged in as: ');
      logger.info(bot.username + ' - (' + bot.id + ')');
  });
  bot.on('message', function (user, userID, channelID, message, evt) {
      // Our bot needs to know if it will execute a command
      // It will listen for messages that will start with `!`
      if (message.substring(0, 1) == '!') {
          var args = message.substring(1).split(' ');
          var cmd = args[0];
  
          args = args.splice(1);
          switch(cmd) {
             // !ping
              case 'ping':
                  bot.sendMessage({
                      to: channelID,
                      message: 'Pong!'
                  });
              break;
              // Just add any case commands if you want to..
           }
       }
  });
  

Answer 1

I recommend using discord.js https://discordjs.guide/creating-your-bot/#creating-the-bot-file Use this code and it works just fine:

const Discord = require('discord.js');
const client = new Discord.Client();

client.once('ready', () => {
    console.log('Ready!');
});

client.login('your-token-goes-here');

Answer 2

The error showed in console is about line 6, however maybe is not what makes the bot appears offline.

logger.add(logger.transports.Console, {
    colorize: true
});

And should be fixed with something like

logger.add(new logger.transports.Console({
    format: winston.format.combine(
        winston.format.colorize(),
        winston.format.simple()
    )
}));

Watch to new word. Now transports require a new object to work and for colorize you can set it combining the formats.
