GitHub - CodyFlame/CodyFire: 🌸 Powerful Codable API requests builder and manager for iOS.

This lib is about network requests with blackjack, roulette and craps!

Using it you will be able to convert your massive API layer code into an awesome convenient controllers with easy and maintainable network requests!

Use Codable models for everything related to API requests:

json payload
url-encoded payload
multipart payload
plain and json response
url query
headers

Wondered? That's only little part of what you will get from this lib! 🍻

Quick examples

How to send GET request

APIRequest<ResponseModel>("endpoint").onSuccess { model in
    //here's your decoded model!
    //no need to check http.statusCode, I already did it for you! By default it's 200 OK
    //of course you can choose which statusCode is equal to success (look at the `POST` and `DELETE` examples below)
}

How to send POST request

APIRequest<ResponseModel>("endpoint", payload: payloadModel)
    .method(.post)
    .desiredStatusCode(.created) //201 CREATED
    .onSuccess { model in
    //here's your decoded model!
    //success was determined by comparing desiredStatusCode with http.statusCode
}

How to send DELETE request

APIRequest<Nothing>("endpoint")
    .method(.delete)
    .desiredStatusCode(.noContent) //204 NO CONTENT
    .onSuccess { _ in
    //here's empty successful response!
    //success was determined by comparing desiredStatusCode with http.statusCode
}

How to send several requests?

You're able to run up to 10 requests one-by-one!

API.employee.all()
    .and(API.office.all())
    .and(API.car.all())
    .and(API.event.all())
    .and(API.post.all())
    .onError { error in
        print(error.description)
    }.onSuccess { employees, offices, cars, events, posts in
   // do what you want with received results!!! 🍻
}

Or you can run unlimited amount of requests one-by-one or at the same time, if you need just a completion handler.

[API.employee.all(), API.office.all(), API.car.all()].flatten().onError {
    print(error.description)
}.onSuccess {
    print("flatten finished!")
}

to run them concurrently just add .concurrent(by: 3) to run by 3 at the same time

Of course you'll be able to send PUT and PATCH requests, send multipart codable structs with upload progress callback, catch errors, even redefine error descriptions for every endpoint. Wondered? 😃 Let's read the whole readme below! 🍻

How to install

CodyFire is available through CocoaPods and SPM.

To install it, simply add the following line in your Podfile:

pod 'CodyFire', '~> 1.15.4'

Or you're looking for reactive code support? I have it! 🍺

for RxSwift https://github.com/MihaelIsaev/RxCodyFire

pod 'RxCodyFire', '~> 1.1.0'
# no need to install `CodyFire` cause it's in dependencies

using this pod you should always import just RxCodyFire and every APIRequest will have .observable

for ReactiveCocoa https://github.com/MihaelIsaev/ReactiveCodyFire

pod 'ReactiveCodyFire', '~> 1.1.0'
# no need to install `CodyFire` cause it's in dependencies

using this pod you should always import just ReactiveCodyFire and every APIRequest will have .signalProducer

How to setup

CodyFire automatically detects which environment you're on, so I suggest you to definitely use this awesome feature 👏

import CodyFire

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        let dev = CodyFireEnvironment(baseURL: "http://localhost:8080")
        let testFlight = CodyFireEnvironment(baseURL: "https://stage.myapi.com")
        let appStore = CodyFireEnvironment(baseURL: "https://api.myapi.com")
        CodyFire.shared.configureEnvironments(dev: dev, testFlight: testFlight, appStore: appStore)
        //Also if you want to be able to switch environments manually just uncomment the line below (read more about that)
        //CodyFire.shared.setupEnvByProjectScheme()
        return true
    }
}

Isn't it cool? 😏

Or you can set different Server URL for every APIRequest

let server1 = ServerURL(base: "https://server1.com", path: "v1")
let server2 = ServerURL(base: "https://server2.com", path: "v1")
let server3 = ServerURL(base: "https://server3.com")

And then initialize your APIRequests like this 🔥

APIRequest(server1, "endpoint", payload: payloadObject)
APIRequest(server2, "endpoint", payload: payloadObject)
APIRequest(server3, "endpoint", payload: payloadObject)

Or in some cases you even can do it like this 😏

APIRequest("endpoint", payload: payloadObject).serverURL(server1)

Create your API controllers

I promise that this is API code architecture from your dreams which are come true!

Create an `API` folder and `API.swift` file inside it

class API {
    typealias auth = AuthController
    typealias task = TaskController
}

Create a folder named `Controllers` inside `API` folder, and create a folder for each controller

API/Controllers/Auth/Auth.swift

class AuthController {}

API/Controllers/Task/Task.swift

class TaskController {}

Create an extension file for each controller's endpoint

Auth login as simple POST request

API/Controllers/Auth/Auth+Login.swift

import CodyFire
extension AuthController {
  struct LoginRequest: JSONPayload {
        let email, password: String
        init (email: String, password: String) {
            self.email = email
            self.password = password
        }
    }

    struct LoginResponse: Codable {
        var token: String
    }

    static func login(_ request: LoginRequest) -> APIRequest<LoginResponse> {
        return APIRequest("login", payload: request).method(.post).addCustomError(.notFound, "User not found")
    }
}

Auth login for Basic auth

API/Controllers/Auth/Auth+Login.swift

import CodyFire
extension AuthController {
    struct LoginResponse: Codable {
        var token: String
    }

    static func login(email: String, password: String) -> APIRequest<LoginResponse> {
        return APIRequest("login").method(.post).basicAuth(email: email, password: password)
            .addCustomError(.notFound, "User not found")
    }
}

Task REST endpoints

Get task by id or a list of tasks by offset and limit

API/Controllers/Task/Task+Get.swift

import CodyFire
extension TaskController {
    struct Task: Codable {
        var id: UUID
        var name: String
    }

    struct ListQuery: Codable {
        var offset, limit: Int
        init (offset: Int, limit: Int) {
            self.offset = offset
            self.limit = limit
        }
    }

    static func get(_ query: ListQuery? = nil) -> APIRequest<[Task]> {
        return APIRequest("task").query(query)
    }

    static func get(id: UUID) -> APIRequest<Task> {
        return APIRequest("task/" + id.uuidString)
    }
}

Create a task

API/Controllers/Task/Task+Create.swift

import CodyFire
extension TaskController {
    struct CreateRequest: JSONPayload {
        var name: String
        init (name: String) {
            self.name = name
        }
    }

    static func create(_ request: CreateRequest) -> APIRequest<Task> {
        return APIRequest("post", payload: request).method(.post).desiredStatusCode(.created)
    }
}

Edit a task

API/Controllers/Task/Task+Edit.swift

import CodyFire
extension TaskController {
    struct EditRequest: JSONPayload {
        var name: String
        init (name: String) {
            self.name = name
        }
    }

    static func create(id: UUID, request: EditRequest) -> APIRequest<Task> {
        return APIRequest("post/" + id.uuidString, payload: request).method(.patch)
    }
}

Delete a task

API/Controllers/Task/Task+Delete.swift

import CodyFire
extension TaskController {
    static func delete(id: UUID) -> APIRequest<Nothing> {
        return APIRequest("post/" + id.uuidString).method(.delete).desiredStatusCode(.noContent)
    }
}

Easily use your API endpoints!

Send login request

API.auth.login(email: "[email protected]", password: "qwerty").onError { error in
    switch error.code {
    case .notFound: print("User not found")
    default: print(error.description)
    }
}.onSuccess { token in
    print("Received auth token: "+ token)
}

Get a list of tasks

API.task.get().onError { error in
    print(error.description)
}.onSuccess { tasks in
    print("received \(tasks.count) tasks")
}

Create a task

API.task.create(TaskController.CreateRequest(name: "Install CodyFire")).onError { error in
    print(error.description)
}.onSuccess { task in
    print("just created new task: \(task)")
}

Delete a task

let taskId = UUID()
API.task.delete(id: taskId).onError { error in
    print(error.description)
}.onSuccess { _ in
    print("just removed task with id: \(taskId)")
}

Multipart example

//declare a PostController
class PostController()
extension PostController {
    struct CreateRequest: MultipartPayload {
        var text: String
        var tags: [String]
        var images: [Attachment]
        var video: Data
        init (text: String, tags: [String], images: [Attachment], video: Data) {
            self.text = text
            self.tags = tags
            self.images = images
            self.video = video
        }
    }

    struct PostResponse: Codable {
        let id: UUID
        let text: String
        let tags: [String]
        let linksToImages: [String]
        let linkToVideo: String
    }

    static func create(_ request: CreateRequest) -> APIRequest<PostResponse> {
        return APIRequest("post", payload: request).method(.post)
    }
}

//then somewhere send creation request!

let videoData = FileManager.default.contents(atPath: "/path/to/video.mp4")!
let imageAttachment = Attachment(data: UIImage(named: "cat")!.jpeg(.high)!,
                                 fileName: "cat.jpg",
                                 mimeType: .jpg)
let payload = PostController.CreateRequest(text: "CodyFire is awesome",
                                           tags: ["codyfire", "awesome"],
                                           images: [imageAttachment],
                                           video: videoData)
API.post.create(payload).onProgress { progress in
    print("tracking post uploading progress: \(progress)")
}.onError { error in
    print(error.description)
}.onSuccess { createdPost in
    print("just created post: \(createdPost)")
}

Easy right? 🎉

How to put `Authorization Bearer` token into every request?

For that we have a global headers wrapper, which is called for every request.

You need to declare it e.g. somewhere in AppDelegate.

There are two options

Use Codable model for headers (recommended)

CodyFire.shared.fillCodableHeaders = {
    struct Headers: Codable {
        var Authorization: String? //NOTE: nil values will be excluded
        var anythingElse: String
    }
    return Headers(Authorization: nil, anythingElse: "hello")
}

Use [String: String] dictionary

CodyFire.shared.fillHeaders = {
    guard let apiToken = LocalAuthStorage.savedToken else { return [:] }
    return ["Authorization": "Bearer \(apiToken)"]
}

How to set a global `unauthorized` handler?

Again, somewhere in AppDelegate declare it like this CodyFire.shared.unauthorizedHandler = { //kick out user }

Handle if network isn't available (e.g. wifi/lte turned off)

.onNetworkUnavailable {
    print("unfortunately there're no internet connection!")
}

Run something right before request started (works only if network is available)

.onRequestStarted {
    print("request started normally")
}

How to avoid log error for request

.avoidLogError()

How to set desired status code and what's that means?

Usually servers response with 200 OK and CodyFire expect to receive 200 OK to call onSuccess handler by default.

You may need to specify another code, e.g. 201 CREATED for some POST requests.

.desiredStatusCode(.created)

or you even can set your custom code

.desiredStatusCode(.custom(777))

How to set some headers for a request?

.headers(["myHeader":"myValue"])
//or for basic auth
.basicAuth(email: "", password: "")

Supported HTTP methods

You may use: GET, POST, PUT, PATCH, DELETE, HEAD, TRACE, CONNECT, OPTIONS

How to switch environments through Xcode's run schemes?

It's really useful feature and I suggest to use it in every iOS project!

Create three schemes named: Development, TestFlight, AppStore like on the screenshot below

TIP: Make sure that they're marked as Shared to have them in git

Then in every scheme in Arguments tab add Environment variable named env with one of those values: dev, testFlight, appStore.

Take a look at example below

Then somewhere in AppDelegate.didFinishLaunchingWithOptions add

CodyFire.shared.setupEnvByProjectScheme()

All done, now you're able to easily switch environments!

How to execute request without onSuccess clojure?

Sometimes useful for DELETE or PATCH requests

APIRequest<Nothing>("endpoint").method(.delete).execute()

How to cancel request?

let request = APIRequest("").execute()
request.cancel()

and you're able to handle cancellation

.onCancellation {
    print("request was cancelled :(")
}

What does custom error means?

You may define your own custom errors, globally or for each request. onError block contains NetworkError object with StatusCode enum, an error description, and a raw response Data. Error description you could change to whatever you want for any error code. By default there are already defined some good descriptions for common errors.

Let's take a look how we can use powerful onError block

.onError { error in
    switch error.code {
    case .notFound: print("It's not found :(")
    case .internalServerError: print("Oooops... Something really went wrong...")
    case .custom(let code): print("My non-standard-custom error happened: " + error.description)
    case .unknown(let code): print("Totally unknown error happened: " + error.description)
    default:
        print("Another error happened: " + error.description)
        if let raw = error.raw, let rawResponse = String(data: raw, encoding: .utf8) {
            print("Raw response: " + rawResponse)
        }
    }
}

More than that!!! In your controller while declaring APIRequest you're able to add your own custom errors!!! 🙀

APIRequest("login")
    .method(.post)
    .basicAuth(email: "[email protected]", password: "qwerty")
    .addError(.notFound, "User not found")

I believe that's really awesome and useful! Finally a lot of things may be declared in one place! 🎉

How to set response timeout?

.responseTimeout(30) //request timeout set for 30 seconds

and of course you're able to catch timeout

.onTimeout {
    //timeout happened :(
}

How to add interactive additional timeout? (my favourite one 😄)

If you want to make sure that your request will take 2 or more seconds (to not be too fast 😅) you can do that

.additionalTimeout(2)

e.g. in case if your request will be executed in 0.5 seconds, onSuccess handler will be fired only in 1.5s after that but in case if your request will take more than 2s then onSuccess handler will be fired immediatelly

How to declare payload model for `multipart` request

Your struct/class just should conform to MultipartPayload protocol

struct SomePayload: MultipartPayload {
    let name: String
    let names: [String]
    let date: Date
    let dates: [Dates]
    let number: Double
    let numbers: [Int]
    let attachment: Data
    let attachments: [Data]
    let fileAttachment: Attachment
    let fileAttachments: [Attachment]
}

Supported payload types

You may conform your struct/class to: FormURLEncodedPayload, MultipartPayload, and JSONPayload

How to declare payload model for `json` request

Your struct/class just should conform to JSONPayload protocol

struct SomePayload: JSONPayload {
    let name: String
    let names: [String]
    let date: Date
    let dates: [Dates]
    let number: Double
    let numbers: [Int]
}

How to declare payload model for `x-www-form-urlencoded` request

Your struct/class just should conform to FormURLEncodedPayload protocol

struct SomePayload: FormURLEncodedPayload {
    let name: String
    let names: [String]
    let date: Date
    let dates: [Dates]
    let number: Double
    let numbers: [Int]
}

How to declare url query params model

Your struct/class just should conform to Codable protocol

struct SomePayload: Codable {
    let name: String
    let names: [String]
    let date: Date
    let dates: [Dates]
    let number: Double
    let numbers: [Int]
}

How to set date decoding/encoding strategy

Our DateCodingStrategy support

secondsSince1970
millisecondsSince1970
formatted(customDateFormatter: DateFormatter) By default all the dates are in yyyy-MM-dd'T'HH:mm:ss'Z' format

You have interesting options here:

you can set global date decoder/encoder

CodyFire.shared.dateEncodingStrategy = .secondsSince1970
let customDateFormatter = DateFormatter()
CodyFire.shared.dateDecodingStrategy = .formatted(customDateFormatter)

you can set date decoder/encoder for request in your controller

APIRequest().dateDecodingStrategy(.millisecondsSince1970).dateEncodingStrategy(.secondsSince1970)

or you even can use different date encoder/decoder for each payload type (highest priority)

struct SomePayload: JSONPayload, CustomDateEncodingStrategy, CustomDateDecodingStrategy {
   var dateEncodingStrategy: DateCodingStrategy
   var dateDecodingStrategy: DateCodingStrategy
}

How to enable/disable logging

e.g. in AppDelegate you may set logging mode

CodyFire.shared.logLevel = .debug
CodyFire.shared.logLevel = .error
CodyFire.shared.logLevel = .info
CodyFire.shared.logLevel = .off

and also you can set log handler

CodyFire.shared.logHandler = { level, text in
    print("manually printing codyfire error: " + text)
}

by default for the AppStore the log level if .off

How you're detecting current environment?

It's easy

#if DEBUG
    //DEV environment
#else
    if Bundle.main.appStoreReceiptURL?.lastPathComponent == "sandboxReceipt" {
        //TESTFLIGHT environment
    } else {
        //APPSTORE environment
    }
#endif

Chained requests

Run up to 10 requests one-by-one!

API.employee.all()
    .and(API.office.all())
    .and(API.car.all())
    .and(API.event.all())
    .and(API.post.all())
    .onError { error in
        print(error.description)
    }.onSuccess { employees, offices, cars, events, posts in
   // do what you want with received results!!! 🍻
}

onRequestStarted, onNetworkUnavailable, onCancellation, onNotAuthorized, onTimeout also available! //TBD: onProgress

I believe it is awesome! Especially for whom who not familiar or don't like reactive programming 🙂

Flatten

If you want to run several requests one-by-one or at the same time but with just completion handler you can do that with .flatten()

[API.employee.all(), API.office.all(), API.car.all()].flatten().onError {
    print(error.description)
}.onSuccess {
    print("flatten finished!")
}

to run them concurrently just add .concurrent(by: 3) to run by 3 at the same time to skip errors also add .avoidCancelOnError() to get progress add .onProgress
