gateway-facade

You wrap HttpClient calls with typed gateway classes by using HttpExtensions for consistent serialization and error handling, organizing endpoints into nested management classes, and returning a uniform ResponseResult<T> type. This centralizes routing and reuse for control panel REST APIs.

Centralizing error handling for REST API calls is achieved by implementing a gateway facade pattern that enforces HttpExtensions and returns a uniform ResponseResult<T> type. This provides consistent error handling across all microservice control panel endpoints.

You register typed HttpClient instances in dependency injection by using the AddGatewayClients configuration method. This sets up the DI container to provide configured, typed HttpClient instances to your gateway classes.

Yes, you can organize control panel API endpoints by domain using nested management classes. These classes group related endpoints together and enable lazy initialization, keeping your gateway facades structured and maintainable.

You need a typed gateway facade for your HttpClient implementation when working with microservice control panel scenarios that require consistent error handling, nested domain management, and dependency injection registration. It abstracts raw HttpClient usage into a reusable pattern.
