Question 1

How to handle errors in Seneca microservices?

Accepted Answer

Seneca provides built-in error handling through callback patterns; you can use try-catch in actions or leverage plugins like seneca-error for structured error responses, ensuring robust failure management in distributed systems.

Question 2

Seneca vs Express.js for building APIs?

Accepted Answer

Seneca excels in microservice architectures with pattern matching and transport independence, while Express.js is better for simple REST APIs; choose Seneca if you need scalable, decoupled services, but expect more initial setup.

Question 3

How to deploy Seneca services in Docker containers?

Accepted Answer

Package each Seneca service as a separate Docker image, using environment variables for configuration and ensuring network connectivity for transport layers; the README's transport examples make this straightforward with HTTP listeners.

Question 4

What are the best practices for structuring Seneca plugins?

Accepted Answer

Keep plugins focused on single responsibilities, use clear pattern naming conventions, and test thoroughly with the --seneca.test flag; the sales tax example in the README illustrates this with isolated command handlers.

Question 5

How does Seneca compare to NestJS for microservices?

Accepted Answer

Seneca offers more flexibility with transport independence and pattern matching, while NestJS provides a more opinionated, TypeScript-friendly framework; Seneca is better for legacy integration, but NestJS suits teams wanting modern tooling.

Question 6

How to implement authentication with Seneca plugins?

Accepted Answer

Use community plugins like seneca-auth or build custom patterns to validate tokens; the plugin ecosystem allows integrating OAuth or JWT by adding middleware actions, though it requires manual setup compared to all-in-one solutions.
