What is the best way to create a link from an image uploaded by the user?

I am trying to create an app that uses IBM Watson Visual Recognition for sortering waste. Watson runs in the backend (node js) and I wanted to develop the application in Vue.

Watson needs a link to an image, and I was thinking of using firebase in order to create the link when an user uploads an image.

My question is: "Is there a better way to do it, considering that the image and its results should be unique to the user an do not have to persist?"

I do not know much about Visual Recognition and just a little of firebase. So, if there is a way to handle things better, please say. Thanks!

What I ended up doing was uploading an image to firebase storage, sending the link to the server, fetching the results, and then deleting the image from firebase.

As per the API documentation, you can submit the image to be classified either as a url or as a readstream. https://cloud.ibm.com/apidocs/visual-recognition/visual-recognition-v3?code=node#classify

The sample provided in the API docs makes use of a readstream :


const fs = require('fs');
const VisualRecognitionV3 = require('ibm-watson/visual-recognition/v3');
const { IamAuthenticator } = require('ibm-watson/auth');

const visualRecognition = new VisualRecognitionV3({
  version: '2018-03-19',
  authenticator: new IamAuthenticator({
    apikey: '{apikey}',
  }),
  serviceUrl: '{url}',
});

const classifyParams = {
  imagesFile: fs.createReadStream('./fruitbowl.jpg'),
  owners: ['me'],
  threshold: 0.6,
};

visualRecognition.classify(classifyParams)
  .then(response => {
    const classifiedImages = response.result;
    console.log(JSON.stringify(classifiedImages, null, 2));
  })
  .catch(err => {
    console.log('error:', err);
  });
