To run the example project, clone the repo, and run pod install
from the Example directory first.
- iOS 10.0+
- Swift 5.1+
- Xcode 11+
RxRestClient is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'RxRestClient'
- Simple way to do requests
- Simple way to have response state in reactive way
- Ability to customization
- Retry on any error
- Handle network reachability status
- Retry on become reachable
- Ability to use absolute and relative urls
- Swift Codable protocol support
- Use custom SessionManager
- Pagination support
- more coming soon
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)
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 absolute 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 absolute 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 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 model generated using nextPage()
function.
