High Level Overview

ServiceConfig

Configuration file, contains base URL, headers and query Parameters to be reused as an interceptor, under any instance.

public protocol NetworkConfigurable {
    var baseURL: URL { get }
    var headers: [String: String] { get }
    var queryParameters: [String: String] { get }
}

DataTransferService

Decode the response into the model and return a error in an case failure.

public protocol DataTransferService {
    typealias CompletionHandler<T> = (Result<T, DataTransferError>) -> Void
    
    @discardableResult
    func request<T: Decodable, E: ResponseRequestable>(with endpoint: E,
                                                       completion: @escaping CompletionHandler<T>) -> NetworkCancellable? where E.Response == T
    @discardableResult
    func request<E: ResponseRequestable>(with endpoint: E,
                                         completion: @escaping CompletionHandler<Void>) -> NetworkCancellable? where E.Response == Void
}

public protocol DataTransferErrorResolver {
    func resolve(error: NetworkError) -> Error
}

public protocol DataTransferErrorLogger {
    func log(error: Error)
}

NetworkService

take the configuration and do the request and log it.

public protocol NetworkService {
    typealias CompletionHandler = (Result<Data?, NetworkError>) -> Void
    func request(endpoint: Requestable, completion: @escaping CompletionHandler) -> NetworkCancellable?
}

public protocol NetworkSessionManager {
    typealias CompletionHandler = (Data?, URLResponse?, Error?) -> Void
    func request(_ request: URLRequest,
                 completion: @escaping CompletionHandler) -> NetworkCancellable
}

public protocol NetworkErrorLogger {
    var  logEnabled: Bool {get set}
    func log(request: URLRequest)
    func log(responseData data: Data?, response: URLResponse?)
    func log(error: Error)
}

Endpoint

Convert path to the URL Request with a certain method, header, body, and query.

public protocol Requestable {
    var path: String { get }
    var isFullPath: Bool { get }
    var method: HTTPMethodType { get }
    var headerParamaters: [String: String] { get }
    var queryParametersEncodable: Encodable? { get }
    var queryParameters: [String: Any] { get }
    var bodyParamatersEncodable: Encodable? { get }
    var bodyParamaters: [String: Any] { get }
    var bodyEncoding: BodyEncoding { get }
    
    func urlRequest(with networkConfig: NetworkConfigurable) throws -> URLRequest
}

extension Requestable {
    /// prepare the url by appening the base url and query parameters. 
    private func url(with config: NetworkConfigurable) throws -> URL { }
    /// prepare the Request by adding headers and bodyParamaters. 
    public func urlRequest(with config: NetworkConfigurable) throws -> URLRequest { }
}

public protocol ResponseRequestable: Requestable {
    associatedtype Response
    var responseDecoder: ResponseDecoder { get }
}
