Logging

Carno.js comes with a built-in logger powered by Pino, offering high-performance JSON logging.

Usage

Inject the LoggerService into your controllers or services.

import { Controller, Get, LoggerService } from '@carno.js/core';

@Controller()
export class AppController {
  constructor(private logger: LoggerService) {}

  @Get()
  index() {
    this.logger.info('Request received!');
    this.logger.error('Something went wrong', { error: 'details' });
    return 'Hello';
  }
}

Configuration

You can configure Pino options via the Carno constructor.

new Carno({
  logger: {
    level: 'debug',
    // other pino options
  }
}).listen();

By default, the logger uses pino-pretty for readable console output in development.
