When I try this out with my API returning an SVG image as blob, the returned image is not rendered, instead the following error box is shown with a "Plugin not supported" message when hovering over it. Same result in different browsers.

Can anybody else confirm this to be working?

Travis appears to be in a bad state for this PR - going to close and reopen.

@shockey if you can (and only if you have time to spare) take a look at my code, see if there is any way to convert a blob to a string, I spent a lot of time on it and could not find any way...

@heldersepu, there is a way but it's pretty weird:

//// source: https://medium.com/programmers-developers/convert-blob-to-string-in-javascript-944c15ad7d52
const blb    = new Blob(["Lorem ipsum sit"], {type: "text/plain"});
const reader = new FileReader();

// This fires after the blob has been read/loaded.
reader.addEventListener('loadend', (e) => {
  const text = e.srcElement.result;
  console.log(text);
});

// Start reading the blob as text.
reader.readAsText(blb);

As for this PR, it looks like the source branch has vanished from your fork, so I can't reopen this - can you restore it and then open a new PR?

[heldersepu]

Ye, I looked into that but it is async and I could not get it to work in a sync way...
The problem with my branch is that I deleted my fork and recreate it, this PR can stay close!
