Configuration

Loggy currently accepts a few different configuration options.

interface LoggyConfig {
  level: string;
  identifier: string;
  color?: boolean;
  compact?: boolean;
  timestamp?: boolean;
}

Level

The level allows your to define what level to expose logs. This is useful for larger production level environments where you may not want to see everything. You can control your log level with env vars like so

  const loggy = CreateLoggy({
    level: `${env.ENVIRONMENT === "dev" ? 'info' : 'error'}` // show info and log messages in dev environments, error and log messages in non-dev environments
    identifier: "my-app",
  });

Identifier

The identifier allows you to prefix messages with a custom string. Useful for if you have multiple services running in the same instance. You can instantiate multiple Loggy instances and prefix them accordingly, for example:

  const serviceLoggy = CreateLoggy({
    level: "error",
    identifier: "myService",
  });

  const dbLoggy = CreateLoggy({
    level: "warn",
    identifier: "myDb",
  });

Will print logs like

7/14/2025 9:16:28 PM [LOG] myService: This message is from your app service
7/14/2025 9:17:14 PM [LOG] myDb: This message is from your db service

Color

The color allows you to toggle the pretty colors on and off. Defaults to true.

Compact

The compact flag will collapse json objects. Defaults to false.

Timestamp

The timestamp flag allows you to toggle showing the timestamp in logs. Defaults to true.
