Error handling and optimizations

Proper error handling is crucial in microservices architecture to ensure reliability and provide meaningful feedback to clients. On the other hand, optimizing your microservices ensures they run efficiently and handle requests quickly, enhancing the overall user experience.

Error handling in microservices

Error handling in microservices is a crucial aspect of building reliable and resilient distributed systems. Errors can occur due to various reasons, such as network failures, service outages, data inconsistencies, or application bugs. Therefore, it is important to have a consistent and effective strategy for handling errors across different microservices.

Here’s how you can handle errors effectively in your Node.js microservices:

• Use HTTP status codes: Utilize appropriate HTTP status codes in your responses. For example, use 400 Bad Request for client errors (for example, validation failures), 404 Not Found for resources that...
