DataRequest

Modularization of data requests using Alamofire with concurrency.

This package encourages a design pattern where the description of an endpoint is encapsulated into the properties of a structure. A similar design to a SwiftUI View. It adds rather than replaces; direct use of Alamofire (or URLSession) is still encouraged. There is also some helpful shorthand.

Example Usage

Define a decodable model returned in a response:

struct Model: Decodable, Sendable { ... }

Specify the configuration of the request endpoint:

struct GetModel: DecodableRequest {
    typealias ResponseBody = Model

    var urlComponents: URLComponents { ... }
    var method: HTTPMethod { ... }
    var headers: HTTPHeaders { ... }
    var body: HTTPBody? { ... }
}

Finally, execute the request in an asynchronous environment:

let model = try await GetModel().request()

Installation

Add to the Package.swift:

dependencies: [
    .package(
        url: "https://github.com/BenShutt/DataRequest.git",
        branch: "main"
    )
]

Uploads

A DecodableRequest is a URLRequestMaker with the configuration properties of a data request defaulted. Since URLRequestMaker conforms to URLRequestConvertible you can use Alamofire directly:

AF.upload(data, with: Endpoint())
    .uploadProgress { progress in ... }
    .decodeValue()

where Endpoint is some URLRequestMaker.

Debug Logging

To log request/responses, make a new Session instance (managing its lifecycle accordingly) with a ResponseEventMonitor event monitor. The ResponseEventMonitor logs the debugDescription of the DataResponse. For example:

extension Session {
    static let debug = Session(eventMonitors: [
        ResponseEventMonitor()
    ])
}

This can be returned in the session property of the DecodableRequest.

GitHub Actions

The .github/workflows/swift.yml GitHub action checks that the Swift package builds and the tests pass using a swift docker container.
