The example (http GET) doesn't compile in ReasonML

`

33 │ / Js.Promise.( /

This has type: Js.Promise.t(unit) (defined as Js.Promise.t(unit)) But somewhere wanted: unit `

My bsconfig.json contains axios:

"bs-dependencies": [ "reason-react", "bs-jest", "bs-axios", "bs-css" ]

@aaron-michaux the example is working, but you're using it in didMount method which should return unit not Js.Promise.t(unit). So you should do something like this:

didMount: (_self) => {
    Js.Promise.(
      Axios.get("/user?ID=12345")
      |> then_((response) => resolve(Js.log(response##data)))
      |> catch((error) => resolve(Js.log(error)))
    );
    ();
}

• return () (unit) obviously. Or you can use standard OCaml function ignore which return unit for any type of parameter passed:

  didMount: (_self) => {
  Js.Promise.(
    Axios.get("/user?ID=12345")
    |> then_((response) => resolve(Js.log(response##data)))
    |> catch((error) => resolve(Js.log(error)))
    |> ignore
  );
  }
