import * as msRestNodeAuth from "@azure/ms-rest-nodeauth";
import { PredictionAPIClient, PredictionAPIModels, PredictionAPIMappers } from "@azure/cognitiveservices-customvision-prediction";
const subscriptionId = process.env["AZURE_SUBSCRIPTION_ID"];

msRestNodeAuth.interactiveLogin().then((creds) => {
  const client = new PredictionAPIClient(creds, subscriptionId);
  const projectId = "ec7b1657-199d-4d8a-bbb2-89a11a42e02a";
  const publishedName = "testpublishedName";
  const imageUrl: PredictionAPIModels.ImageUrl = {
    url: "testurl"
  };
  const application = "testapplication";
  client.classifyImageUrl(projectId, publishedName, imageUrl, application).then((result) => {
    console.log("The result is:");
    console.log(result);
  });
}).catch((err) => {
  console.error(err);
});
