How to Save Camera Images in an Ionic App

This short tutorial will show you how to save images from your device camera into Appery.io database.

Create a new Ionic project and database.
Add the Camera Service plug-in and File Upload App plug-in into the project by going to Project > CREATE NEW > From Plug-in, in the Builder.
Create a page CameraPage with 2 buttons Camera and Upload with corresponding attributes and the component Image to display the result:
On the Scope tab add this code for the Camera button:
var requestData = {}; Apperyio.get("Camera_getPicture")(requestData).then( function(success){ $scope.im.image = success.image; $scope.$apply(); }, function(error){ });

var requestData = {};
Apperyio.get("Camera_getPicture")(requestData).then(
function(success){
$scope.im.image = success.image;
$scope.$apply();
},
function(error){
});

Then, add this code for the Upload button:

function dataURLtoFile(dataurl, filename) {
var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
while(n--){
u8arr[n] = bstr.charCodeAt(n);
}
return new File([u8arr], filename, {type:mime});
}

var filepointer = dataURLtoFile($scope.im.image, 'test.png');
$scope.files.push({filename:"test.png", filepointer: filepointer});


if ($scope.files.length === 0) {
alert('No file for upload');
return;
}

var requestData = Apperyio.EntityAPI('FileDB__files_upload_service.request');
var user_scope = $scope.user;
var files_scope = $scope.files;
var formData = new FormData();
requestData.data = _.pluck($scope.files, 'filepointer');

Apperyio.get("FileDB__files_upload_service")(requestData).then(

function(success){
alert('All files has been successfully uploaded.');
},
function(error){

},
function(notify){

});

function dataURLtoFile(dataurl, filename) {

var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],

bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);

while(n--){

u8arr[n] = bstr.charCodeAt(n);

}

return new File([u8arr], filename, {type:mime});

}

var filepointer = dataURLtoFile($scope.im.image, 'test.png');

$scope.files.push({filename:"test.png", filepointer: filepointer});

if ($scope.files.length === 0) {

alert('No file for upload');

return;

}

var requestData = Apperyio.EntityAPI('FileDB__files_upload_service.request');

var user_scope = $scope.user;

var files_scope = $scope.files;

var formData = new FormData();

requestData.data = _.pluck($scope.files, 'filepointer');

Apperyio.get("FileDB__files_upload_service")(requestData).then(

function(success){

alert('All files has been successfully uploaded.');

function(error){

function(notify){

});

Finally, enter tour database_id and master_key in FileDB_settings:

And, that’s it! (Please remember that this app should be tested on a real device.)
