    #gaato/mttp

    HTTP for MoonBit with the split of responsibilities of Scala's sttp family, on top of gaato/http: a client that owns retries, rate limits and deadlines, server-sent events, multipart bodies, cookies, endpoint descriptions with server and client interpreters, a router and OpenAPI documents. It does no I/O itself and runs on wasm-gc, wasm, js and native.

    Status: this version is being rebuilt in the mttp repository. The packages arrive one at a time: jsonkit, sse, multipart, cookie, schema, the OpenAPI document model apispec, the client with its retry rules, rate limits, the cookie wrapper, the test doubles, typed endpoints, endpoint test helpers, the router and OpenAPI projection are here.

    #Install

    moon add gaato/mttp

    A package that names @http types imports gaato/http too, so list both in your moon.mod.

    #Packages

    gaato/mttp/client/retryRetry rules and decisions as data, and the Retry-After parsers
    gaato/mttp/client/ratelimitBounded window state, grouped pacing, global quotas and header-driven admission on an injected clock
    gaato/mttp/client/cookiesA CookieJar backend wrapper; put it inside FollowRedirects to process every hop

    #Usage

    Build an upload and read a server-sent event stream. Neither touches the network: a transport from gaato/http-async, or a test double, sends the request and supplies the chunks.

    ///|
    test "an upload and an event stream" {
      let request = @multipart.body(
        @http.Request::post("https://example.com/upload"),
        [@multipart.Part::json("meta", { "draft": true })],
        boundary=@multipart.make_boundary(() => 0.25),
      )
      assert_true(request.headers.get("content-type") is Some(_))
      let parser = @sse.SseParser::new()
      let events = parser.feed(b"data: one\n\ndata: tw")
      events.append(parser.feed(b"o\n\n"))
      assert_eq(events.map(e => e.data), ["one", "two"])
    }
