You are building a chat application in Node.js and need to handle different types of messages like text, images, and files. How would you structure the event emitters and listeners to handle different message types efficiently?

  • Create separate events for each message type: event.emit('textMessage', message)
  • Use a single event and send message type as a parameter: event.emit('message', messageType, message)
  • Create a listener for each message type: event.on('textMessage', textMessageCallback)
  • Create a single listener and use conditional checks to handle message types: event.on('message', messageCallback)
To efficiently handle different message types in a chat application, it's best to create separate events for each message type (e.g., 'textMessage', 'imageMessage', 'fileMessage'). This approach keeps the code organized and allows specific handlers for each message type. The other options may lead to less structured and harder-to-maintain code.
