How can I create custom transports in Winston logger?

How can I create custom transports in Winston logger?

To create custom transports in Winston, you can extend the TransportStreamOptions and implement the log method.

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 to file: ${info.message}`);
    callback();
  }
}

How do I use this custom transport in my Winston logger setup?

You can use your custom transport like this:

const winston = require('winston');
const CustomFileTransport = require('./CustomFileTransport');

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

What if I want to log to a database instead?

You can modify the log method in your custom transport to insert logs into your database instead of logging to a file.
