How can I create custom transports in Winston logging?

How can I create custom transports in Winston logging?

To create custom transports in Winston, you can extend the Transport class and implement the required methods.

Can you give me an example of a custom transport?

Sure! Here's a simple example of a custom transport that logs to a file:

const { TransportStreamOptions } = require('winston-transport');

class CustomFileTransport extends TransportStreamOptions {
  log(info, callback) {
    // Custom logic to log to a file
    console.log(`Logging info: ${info.message}`);
    callback();
  }
}

What methods do I need to implement in my custom transport?

You need to implement the log method, which is called whenever a log event is emitted. You can also implement other methods for additional functionality.

How do I add my custom transport to the Winston logger?

You can add your custom transport by passing it to the transports array when creating a Winston logger instance, like this:

const winston = require('winston');
const customTransport = new CustomFileTransport();

const logger = winston.createLogger({
  transports: [customTransport]
});
