an async example

How to use async clients in this case with axios:

import axios, { AxiosPromise } from "axios";
import { ServiceClient as ExampleClient } from "./some/generated/client";

// axios transport
let getTransport = endpoint => async <T>(method, args = []) => {
	return new Promise<T>(async (resolve, reject) => {
		try {
			let axiosPromise: any = await axios.post<T>(
				endpoint + encodeURIComponent(method),
				JSON.stringify(args),
			);
			return resolve(axiosPromise.data);
		} catch (e) {
			return reject(e);
		}
	});
};

let client = new ExampleClient(getTransport(ExampleClient.defaultEndpoint));

export async function test() {
	try {
    let result = await client.getResult();
    console.log("here is the result", result);
	} catch (e) {
		// e => network?
		// e => json
    // e => domain error type
    console.error("something went wrong ...", e);
  }
}
