Implement circuit breaker pattern for external API calls?

Use @nestjs/terminus or opossum lib; track failures, open circuit after threshold. Fallback to cache/stub; half-open after timeout. Integrate with health checks.

‍Example:-

Code

CircuitBreaker('api-call', {
  timeout: 5000,
  errorThresholdPercentage: 50,
  resetTimeout: 30000
})(async () => await externalApi.fetch());
