Error: Cannot find module 'some/path/Class'

Hello @derian-all-win-software

can you please show me the content of the file WinstonLogger

Remember, every single service/dependency needs to be exported as default or use https://github.com/zazoomauro/node-dependency-injection/wiki/NamedMultiple

Hi @zazoomauro, this is the content of the WistonLogger class:

import winston, { Logger as WinstonLoggerType } from 'winston';
import Logger from '../domain/Logger';

enum Levels {
  DEBUG = 'debug',
  ERROR = 'error',
  INFO = 'info'
}

class WinstonLogger implements Logger {
  private logger: WinstonLoggerType;

  constructor() {
    this.logger = winston.createLogger({
      format: winston.format.combine(
        winston.format.prettyPrint(),
        winston.format.errors({ stack: true }),
        winston.format.splat(),
        winston.format.colorize(),
        winston.format.simple()
      ),
      transports: [
        new winston.transports.Console(),
        new winston.transports.File({ filename: `logs/${Levels.DEBUG}.log`, level: Levels.DEBUG }),
        new winston.transports.File({ filename: `logs/${Levels.ERROR}.log`, level: Levels.ERROR }),
        new winston.transports.File({ filename: `logs/${Levels.INFO}.log`, level: Levels.INFO })
      ]
    });
  }

  debug(message: string) {
    this.logger.debug(message);
  }

  error(message: string | Error) {
    this.logger.error(message);
  }

  info(message: string) {
    this.logger.info(message);
  }
}
export default WinstonLogger;

The Logger interface would look like this:

export default interface Logger {
  debug(message: string): void;
  error(message: string | Error): void;
  info(message: string): void;
}
