The above code worked for me in angular 2+ application

The notable edits I made to work:

changed from

var file = new Blob([result.data], {type: 'application/pdf'});

to

var file = new Blob([result], {type: 'application/pdf'});

and
from this

$http.get('https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf', { responseType: 'arraybuffer' }).then(function (response) {
                return response;
            });

to

$http.get('https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf', { responseType: 'arraybuffer' });

Solution 3

For IE just add this:

if (window.navigator && window.navigator.msSaveOrOpenBlob) {
   window.navigator.msSaveOrOpenBlob(result, fileName);
}
