Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@jvlk/rescript-future) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

  <div>
    <button
      onClick={_ => {
        request->Future.reset // reset the future to make sure the Abort Controller is new
        Console.log("clicked!")
        let _ = request->Future.fold(Console.error, Console.log)
      }}>
      {"Start"->React.string}

    <button
      onClick={_ => {
