how to export data into CSV and PDF files using angularjs - angularjs

Question

I want to, when i click on button (separate for both CSV and PDF), it automatically download in CSV and PDF file with correct Formatting.
this CSV code i want to add PDF inside code
$scope.downloadData = function() {
var datasets = $scope.datasets.reverse();
var file_name = $scope.m_id+ '.csv';
var dataUrl = 'data:text/csv;charset=utf-8,';
var json = [];
if(datasets !== null) {
for(idx = 0; idx < datasets.length; idx++) {
var dataset = datasets[idx].data;
var time = datasets[idx].timestamp;
time = $filter('date')(time, "dd/MMMM/yyyy-hh:mm a");
dataset.time = time;
json.push(dataset);
}
var fields = Object.keys(json[0]);
var csv = json.map(
function(row) {
return fields.map(
function(fieldName) {
return '"' + (row[fieldName] || '') + '"';
}
);
}
);
csv.unshift(fields);
var csv_str = csv.join('%0A');
var downloadURL = dataUrl + csv_str;
var saveAs = function(uri, filename) {
var link = document.createElement('a');
if (typeof link.download === 'string') {
document.body.appendChild(link); // Firefox requires the link to be in the body
link.download = filename;
link.href = uri;
link.target = "_blank";
link.click();
document.body.removeChild(link); // remove the link when done
} else {
location.replace(uri);
}
};
saveAs(downloadURL, file_name);
} else {
$scope.err_msg = 'Failed to get data. Try reloading the page.';
}
};
I try some of script i found on internet, but it is not working, some have formatting issue and save have downloading.
In Advance Thanks.

You should use this awesome library for pdf/csv or whatever else formats.. File Saver
Here's is code example, service created using FileSaver
function download(api, file, contentType) {
var d = $q.defer();
$http({
method: 'GET',
url: api,
responseType: 'arraybuffer',
headers: {
'Content-type': contentType
}
}).success(function(response) {
var data = new Blob([response], {
type: contentType+ ';charset=utf-8'
});
FileSaver.saveAs(data, file);
d.resolve(response);
}).error(function(response) {
d.reject(response);
});
return d.promise;
}
file input is name of file, you can use same service and pass the types and file names direct from controller.
Let;s you service name is homeService
for pdf call
homeservice.download('/api/download/whaever', 'export.pdf', 'application/pdf')
