core-dotenv

Base configuration class that uses env-var and dotenv

Installation:

class AppConfig extends BaseConfig {
  port = this.get('PORT').default(3000).asPortNumber()
}
const config = new AppConfig()
console.log(config.port) // 3000

Env names can also be typed like this:

type Env = { PORT: string; HOST: string }
