Communicator provides a simple way to construct OkHttp requests as monix.Tasks which is equipped with a beautiful functional interface and comes with first class support for cancellation.

To construct requests, the OkHttp builder API is used.
Use the OkHttp builder API to construct requests which are then lifted into io.taig.communicator.request.Request.
val headers = new OkHttpRequestBuilder().
url("https://github.com/").
header("X-API-Key", "foobar").
build()
val request: Request = Request(headers)There are several ways to transform a Request to an executable Task[Response].
// Ignores response body
val ignoreBody: Task[Response[Unit]] = request.ignoreBody
// Parses response body to a String
val parse: Task[Response[String]] = request.parse[String]To use Communicator on the Android platform please extend your ProGuard rules by the following instructions:
proguardOptions ++=
"-dontnote okhttp3.internal.**" ::
"-dontnote monix.execution.internals.**" ::
"-dontwarn io.circe.generic.util.macros.**" ::
"-dontwarn monix.execution.internals.**" ::
"-dontwarn okio.**" ::
"-dontwarn org.jctools.**" ::
"-dontwarn org.slf4j.**" ::
NilYou might also use existing platform Executors to provide a monix Scheduler:
import android.os.AsyncTask
import android.util.Log
import monix.execution.Scheduler
implicit val PoolScheduler: Scheduler = Scheduler {
ExecutionContext.fromExecutor(
AsyncTask.THREAD_POOL_EXECUTOR,
t ⇒ Log.e("PoolScheduler", "Failure during asynchronous operation", t)
)
