Usage

const useAndThrow = require('download-use-throw');
const path = require('path');

// path to the directory to which
// images are temporarily downloaded
const dirPath = path.join(__dirname, '/temp');

// url of the image to be downloaded
const imgUrl = "https://i.ytimg.com/vi/YQHsXMglC9A/maxresdefault.jpg";

// use and throw
useAndThrow(imgUrl, dirPath, imageHandler);

// function to apply on the downloaded image
function imageHandler(err, pathToImage, done) {
    if(err){
        // handle err

        return done(); // call to done will trigger the deletion process.
    }

    // use the image
    useTheImage(pathToImage); // your function
    // ...
    // ...
    // ...

    // when you finished using the image, call done()
    // which will trigger the deletion process
    done();
}

Call done() when you finished using the image, or you finished handling errors. It will initiate the deletion process.
