AngularJS - Receive and download CSV

Question

I am using a nodeJS program as a server and an AngularJS web application as the client.

To create the CSV I\'m using the \"express-csv\" library (https://www.npmjs.c

Answer 1

There are ways of downloading csv. First approach is to create a tag and click it

Add the mimeType in below code data:application/octet-stream

var a = document.createElement('a');
 a.href = 'data:'+mimeType+';charset=utf-8;base64,' + response;
 a.target = '_blank';
 a.download = "name the file here";
 document.body.appendChild(a);
 a.click(); 

But this solution doesn't work on IE>9 and safari>6

because safari doesn't follow download attribute for anchor tag

so for safari you can use filesaver.js

and IE this solution will work

if (window.navigator.msSaveOrOpenBlob){
                // base64 string
                var base64str = response;

                // decode base64 string, remove space for IE compatibility
                var newstr =base64str.replace(/\s/g, '');
                var binary = atob(newstr);

                // get binary length
                var len = binary.length;

                // create ArrayBuffer with binary length
                var buffer = new ArrayBuffer(len);

                // create 8-bit Array
                var view = new Uint8Array(buffer);

                // save unicode of binary data into 8-bit Array
                for (var i = 0; i < len; i++) {
                 view[i] = binary.charCodeAt(i);
                }

                // create the blob object with content-type "application/csv"               
                var blob = new Blob( [view], { type: mimeType });
                window.navigator.msSaveOrOpenBlob(blob, "Name your file here");
            }
