Currently it provides: 5 | 6 | - A `JSScheduler` class that implements [the `Scheduler` 7 | protocol](https://developer.apple.com/documentation/combine/scheduler). This allows you to use 8 | time-dependent Combine operators such as 9 | [`measureInterval`](), 10 | [`debounce`](), 11 | [`throttle`](), 12 | and 13 | [`timeout`]() 14 | in the browser environment. 15 | - A [`TopLevelDecoder`](https://developer.apple.com/documentation/combine/topleveldecoder) 16 | implementation on [`JSValueDecoder`](https://swiftwasm.github.io/JavaScriptKit/JSValueDecoder/). 17 | - A `publisher` property on [`JSPromise`](https://swiftwasm.github.io/JavaScriptKit/JSPromise/), 18 | which converts your [JavaScript `Promise`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) instances to Combine publishers. 19 | 20 | ## Example 21 | 22 | Here's an example of a timer that fetches a UUID from a remote server every second, parses it 23 | with `JSValueDecoder`, and then displays the result as text: 24 | 25 | ```swift 26 | import JavaScriptKit 27 | import OpenCombine 28 | import OpenCombineJS 29 | 30 | private let jsFetch = JSObject.global.fetch.function! 31 | func fetch(_ url: String) -> JSPromise { 32 | JSPromise(jsFetch(url).object!)! 33 | } 34 | 35 | let document = JSObject.global.document 36 | var p = document.createElement("p") 37 | _ = document.body.appendChild(p) 38 | 39 | var subscription: AnyCancellable? 40 | 41 | let timer = JSTimer(millisecondsDelay: 1000, isRepeating: true) { 42 | subscription = fetch("https://httpbin.org/uuid") 43 | .publisher 44 | .flatMap { 45 | JSPromise($0.json().object!)!.publisher 46 | } 47 | .mapError { $0 as Error } 48 | .map { Result.success($0.uuid.string!) } 49 | .catch { Just(.failure($0)) } 50 | .sink { 51 | let time = JSDate().toLocaleTimeString() 52 | switch $0 { 53 | case let .success(uuid): 54 | p.innerText = .string("At \(time) received uuid \(uuid)") 55 | case let .failure(error): 56 | p.innerText = .string("At \(time) received error \(error)") 57 | } 58 | } 59 | } 60 | ``` 61 | 62 | ### Code of Conduct 63 | 64 | This project adheres to the [Contributor Covenant Code of 65 | Conduct](https://github.com/swiftwasm/.github/blob/main/CODE_OF_CONDUCT.md). 66 | By participating, you are expected to uphold this code.
