Logging is a very necessary part of development. We log for debugging, saving exception, information etc.

That's why fortjs provides a default logger which is very simple & logs everything in console. The advantage of provided logger is that you don't need to import it everywhere.

The logger is a class member of all components i.e controller, shield, wall, guard. Let's see an example -

import { Controller, Worker } from "fortjs";

export class UserController extends Controller {

   @Worker()
   async getAllUsers(){
       const users = [{
           id:1,
           name:'ujjwal'
       }];
       // log users
       this.logger.debug('users are', users);
   }
}

But you might want to log everything in files or database, so want to customize the logger. Logger can be customized very easily by creating a class & extending Logger

import { Logger } from 'fortjs';

export class CustomLogger extends Logger {
    debug(message) {
        // do anything with message
    }

}

Logger has following methods available -

  • debug(…args)
  • info(…args)
  • error(…args)
  • log(…args)


Since you are extending, you can create your own method too.
