How to use

You can just import HTTPClient to use it.

1. Implement a request body structure that conforms to the Encodable protocol. (Optional)

   struct RegisterUserRequestBody: Encodable {
       let name: String
       let description: String
   }

2. Implement a response body structure that conforms to the Decodable protocol.

   struct RegisterUserResponseBody: Decodable {
       let id: String
   }
   
   extension RegisterUserResponseBody {
       func convertToUserID() -> UserID { .init(id: self.id) }
   }

3. Implement a request structure that conforms to the Request protocol.

   import HTTPClient
   
   struct RegisterUserRequest: Request {
       typealias ResponseBody = RegisterUserResponseBody
       var path: String { "user/create_user" }
       var httpMethod: HTTPMethod { .post }
       var httpHeaders: [HTTPHeaderField: String]? { [.contentType: ContentType.applicationJson.rawValue] }
   }

4. Create an instance of the HTTPClient class and call the request method.

   struct UserID: Identifiable, Equatable {
       let id: String
   }

   protocol VersatileRepository {
       func registerUser(name: String, description: String) async throws -> UserID
   }

   import HTTPClient
   
   final class VersatileAPIClient {
       static let shared = VersatileAPIClient()
       
       private let httpClient = HTTPClient(baseURLString: "https://example.com/api/")
   }
   
   extension VersatileAPIClient: VersatileRepository {
       func registerUser(name: String, description: String) async throws -> UserID {
           let requestBody = RegisterUserRequestBody(name: name, description: description)
           let responseBody = try await httpClient.request(RegisterUserRequest(), requestBody: requestBody)
           return responseBody.convertToUserID()
       }
   }

   do {
       let userID = try await VersatileAPIClient.shared.registerUser(name: "Uhooi", description: "Green monster.")
       // Do something.
   } catch {
       // Do error handling.
       print(error)
   }
