I get a byte[] file from my server with the content of a file. I know the name and the content-type. So far I have tried the following for downloading the file:

const a = document.createElement('a');

document.body.appendChild(a);

a.style.display = 'none';



const file = new Blob([content], {type: 'text/plain'});

const url = window.URL.createObjectURL(file);

a.href = url;

a.download = test.txt;

a.click();

window.URL.revokeObjectURL(url);

But this solution just downloads a text file with the binary content in it. How can I convert the binary data to the correspondent file type in the client side using JavaScript/Typescript? Thanks!
