Question 1

How do I add custom middleware to a go-zero service?

Accepted Answer

go-zero allows integrating custom middlewares into its framework via the service context or handler layers. You can define them in the code structure generated by goctl, though the README emphasizes built-in middlewares for resilience.

Question 2

Is go-zero better than Gin for building microservices?

Accepted Answer

go-zero is specifically designed for microservices with built-in resilience, service mesh, and code generation, while Gin is a lighter HTTP framework. For complex, distributed systems, go-zero offers more out-of-the-box features, but Gin might be simpler for basic APIs without microservices needs.

Question 3

Does go-zero support WebSocket or real-time communication?

Accepted Answer

The README focuses on HTTP and RPC for microservices; WebSocket support isn't explicitly mentioned. While you can integrate Go's standard libraries, go-zero's strengths are in request-response patterns and resilience for traditional APIs.

Question 4

How to handle database transactions in go-zero?

Accepted Answer

go-zero provides a service context to pass dependencies like databases to the logic layer. You can use Go's database/sql or ORMs manually, but specific transaction handling patterns are left to the developer, as the framework focuses on API and resilience layers.

Question 5

Can I use go-zero without the code generation tools?

Accepted Answer

Technically yes, but it's not recommended. go-zero's productivity benefits, like auto-request validation and structured code, stem from goctl. Manual setup would bypass key features and require more boilerplate code.

Question 6

What are the deployment options for go-zero services?

Accepted Answer

go-zero services are standard Go binaries, deployable via Docker, Kubernetes, or any cloud platform. The framework includes service discovery and load balancing features for cloud-native environments, as shown in its architecture diagrams.
