To log full stack traces with Winston 3 in Node.js, you can use the format.errors() method provided by Winston. Here’s how you can set it up:

Steps to Log Full Stack Traces with Winston 3:

Install Winston:

Ensure you have Winston installed in your Node.js project:

npm install winston

Configure Winston with Full Stack Trace Logging:

Use format.errors() to log full stack traces. Here's an example setup:

const { createLogger, format, transports } = require('winston');

const logger = createLogger({

  level: 'info',

  format: format.combine(

    format.timestamp(),

    format.errors({ stack: true }), // Enables logging full stack traces

    format.splat(),

    format.json()

  ),

  transports: [

    new transports.Console()

    // Add more transports if needed, like file or database

  ],

});

// Example usage

try {

  // Your code that might throw an error

  throw new Error('Example error');

} catch (error) {

  logger.error(`Error occurred: ${error.message}`, { error });

}
