How to use

First of all you need to create struct of your response state and implement ResponseState protocol.

struct RepositoriesState: ResponseState {

    typealias Body = Data

    var state: BaseState?
    var data: [Repository]?

    private init() {
        state = nil
    }

    init(state: BaseState) {
        self.state = state
    }

    init(response: (HTTPURLResponse, Data?)) {
        if response.0.statusCode == 200, let body = response.1 {
            self.data = try? JSONDecoder().decode(RepositoryResponse.self, from: body).items
        }
    }

    static let empty = RepositoriesState()
}

It is required to mention expected Body type (String or Data).

After that you need to create request model:

struct RepositoryQuery: Encodable {
    let q: String
}

Then you can do the request to get repositories:

import RxSwift
import RxRestClient

protocol RepositoriesServiceProtocol {
    func get(query: RepositoryQuery) -> Observable<RepositoriesState>
}

final class RepositoriesService: RepositoriesServiceProtocol {

    private let client = RxRestClient()

    func get(query: RepositoryQuery) -> Observable<RepositoriesState> {
        return client.get("https://api.github.com/search/repositories", query: query)
    }
}

In order to customize client you can use RxRestClientOptions:

var options = RxRestClientOptions.default
options.addHeader(key: "x-apikey", value: "<API_KEY>")
client = RxRestClient(baseUrl: <BASE _URL>), options: options)

Relative vs absalute url

In order to use relative url you need to give <BASE_URL> when initializing client object.

let client = RxRestClient(baseURL: <BASE_URL>)

When calling any request you can provide either String endpoint or absalute URL. If you will String it will be appended to baseURL.

client.get("rest/contacts")

If baseURL is nil then it will try to convert provided String to URL.

In order to use absalute url even when your client has baseURL you can provide URL like this:

if let url = URL(string: "https://api.github.com/search/repositories") {
    client.get(url: url, query: ["q": search])
}

Pagination

Pagination support is working only for GET requests. In order to have pagination (or infinite scrolling) feature you need to implement following protocols for query and response models:

For query model you need to implement PagingQueryProtocol:

struct RepositoryQuery: PagingQueryProtocol {

    let q: String
    var page: Int

    init(q: String) {
        self.q = q
        self.page = 1
    }

    func nextPage() -> RepositoryQuery {
        var new = self
        new.page += 1
        return new
    }
}

For response model you need to implement PagingResponseProtocol:

struct RepositoryResponse: PagingResponseProtocol {
    let totalCount: Int
    var repositories: [Repository]

    private enum CodingKeys: String, CodingKey {
        case totalCount = "total_count"
        case repositories = "items"
    }

    // MARK: - PagingResponseProtocol
    typealias Item = Repository

    static var decoder: JSONDecoder {
        return .init()
    }

    var canLoadMore: Bool {
        return totalCount > items.count
    }

    var items: [Repository] {
        get {
            return repositories
        }
        set(newValue) {
            repositories = newValue
        }
    }

}

For response states you need to use PagingState class or custom subclass:

final class RepositoriesState: PagingState<RepositoryResponse> {
    ...
}

After having all necessary models you can do your request:

client.get("https://api.github.com/search/repositories", query: query, loadNextPageTrigger: loadNextPageTrigger)

loadNextPageTrigger is an Observable with Void type in order to trigger client to do request for next page using new query moderl generated using nextPage() function.

Logger

In order to log curl command of sent request you can use RxRestClientOptions.logger option. For just printing debug description to console you can use builtin DebugRxRestClientLogger logger.

If you prefer to have a custom logger, for example, log requests to the file, you need to implement RxRestClientLogger protocol and pass it as an option.
