Class ConfigModule

Example

// Define config namespaces
const databaseConfig = registerAs('database', (env) => ({
  url: env.DATABASE_URL,
  maxConnections: 10
}))

const emailConfig = registerAs('email', (env) => ({
  provider: env.EMAIL_PROVIDER,
  from: { name: 'App', email: 'noreply@example.com' }
}))

// Register in module
@Module({
  imports: [
    ConfigModule.forRoot({
      load: [databaseConfig, emailConfig],
      validateSchema: AppConfigSchema
    })
  ]
})
export class AppModule {}

// Inject config
constructor(
  @inject(CONFIG_TOKENS.ConfigService) private config: IConfigService,
  @inject(databaseConfig.KEY) private dbConfig: DatabaseConfig
) {
  // Use dot notation
  const url = this.config.get('database.url')

  // Or inject namespace directly
  const url = this.dbConfig.url
}
