Using async/await

const addImage = (myBlob) => {
    let objectURL = URL.createObjectURL(myBlob);
    let image = document.createElement('img');
    image.src = objectURL;
    document.body.appendChild(image);
}

async function myFetch() {
    let response = await fetch('http://localhost:8081/coffee.jpg');

    if(!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`);
    } else {
        return await response.blob();

    }
}

myFetch()
.then(addImage)
.catch(e => {
    console.log('Ocorreu um problema com sua operação de busca: ' + e.message);
});
