Swift Platform Swift Package Manager CocoaPods Compatible

RealHTTP is a lightweight yet powerful async-based HTTP library made in Swift.
This project aims to make an easy-to-use, effortless HTTP client based on all the best new Swift features.

What will you get?

Below is a simple HTTP call in RealHTTP.

let todo = try await HTTPRequest("")

One line of code, including the automatic decode from JSON to object.

Of course, you can fully configure the request with many other parameters. Take a look here:

let req = HTTPRequest {
  // Setup default params
  $0.url = URL(string: "https://.../login")!
  $0.method = .post
  $0.timeout = 15

  // Setup some additional settings
  $0.redirectMode = redirect
  $0.maxRetries = 4
  $0.headers = HTTPHeaders([
    .init(name: .userAgent, value: myAgent),
    .init(name: "X-API-Experimental", value: "true")
  // Setup URL query params & body
  $0.addQueryParameter(name: "full", value: "1")
  $0.addQueryParameter(name: "autosignout", value: "30")
  $0.body = .json(["username": username, "pwd": pwd])
let _ = try await req.fetch()

The code is fully type-safe.

What about the stubber?

Integrated stubber is perfect to write your own test suite:

That's a simple stubber which return the original request as response:

let echoStub = HTTPStubRequest().match(urlRegex: "*").stubEcho()
HTTPStubber.shared.add(stub: echoStub)

Of course you can fully configure your stub with rules (regex, URI template and more):

// This is a custom stubber for any post request.
var stub = HTTPStubRequest()
      .stub(for: .post, { response in
        response.responseDelay = 5
        response.headers = HTTPHeaders([
          .contentType: HTTPContentType.bmp.rawValue,
          .contentLength: String(fileSize,
        response.body = fileContent
HTTPStubber.shared.add(stub: stub)

That's all!
