This library extends the default ConsoleLogger class from NestJS to allow writing the logs to console and log file. One file per logger instance is created.

Usage:

Import in app.module.ts:

@Module({
  imports: [
    LoggerTaModule.register({
      path: './logs',
    })
  ],
})
export class AppModule {}

Create instance in services or components:

export class AuthService {

   logger = new LoggerTaService(AuthService.name)

    constructor() {
        this.logger.debug(`Service started!`);
        this.logger.error(`Service started!`);
        this.logger.warn(`Service started!`);
        this.logger.log(`Service started!`);
    }
}

Log levels hierarchy:

'debug': ['debug', 'log', 'warn', 'error']
'info': ['log', 'warn', 'error']
'warn': ['warn', 'error']
'error': ['error']

To set log level an environment variable must be declared: LOG_LEVEL=DEBUG, if not declared default is ERROR
