Java script is not writing the logs into file but showing the logs on console

Question

I am trying to create a logfile where I want to write everything info/error/warn etc.

Below is my code where I can see the logs on console but the script is not writing into a file:

var log4js = require('log4js');
log4js.configure({
  appenders: {
    cleanupLogs: {
      type: 'file',
      filename: 'QuoteCleanup.log'
    },
    console: {
      type: 'console'
    }
  },
  categories: {
    default: {
      appenders: ['console'],
      level: 'trace'
    }
  }
});

var log = log4js.getLogger();

Can you show us an example on how you use your `log` object? — Sami Hult, Nov 08 '17 at 08:06

You can use this devtools snippet shown below to create a console.save method. It creates a FileBlob from the input, and then automatically downloads it.

Edited I just edited my answer try this one and tell if this works for you

log4js.configure({
  appenders: {
    everything: {
      type: 'file',
      filename: 'QuoteCleanup.log'
    }
  },
  categories: {
    default: {
      appenders: ['everything'],
      level: 'debug'
    }
  }
});

const logger = log4js.getLogger();
logger.debug('I will be logged in QuoteCleanup.log');

its a bit hard to get that without seeing a running code snippet or example. – Muhammad Omer Aslam Nov 07 '17 at 13:37
If you try to create a javascript with my code it will work and it is just printing the logs to console but not writing in the file – Anuj Vaishampayan Nov 08 '17 at 05:59
