Send GET request and redirect response to browser to download the file

I have a JavaScript application that uses REST API server as a data provider.

There is one method on API that takes GET request and returns raw response that contains email (as far as I can see there is some kind of .eml content).

I use a simple xmlhttprequest.

The question is: how could I take a response (the file content) and delegate it ti browser so the browser can begin a downloading process ?

Is it possible to do at all with GET method ?

Depending on how you have your client running you could use local storage.

to store the item

localStorage.setItem('NAME', DATA);

and to retrieve

localStorage.getItem('NAME');

and to delete

localStorage.removeItem('NAME');

and then set up a callback or promise to render into the html. If you use axios you can set this up with a promise https://github.com/mzabriskie/axios

Javascript does not support downloading and saving arbitrary files on a user's computer due to obvious security concerns.

There are, however, a few ways to indirectly trigger the download using javascript. One of those ways would be using an invisible iframe and setting the source to the path towards the file.
