Base64 conversion for AngularJS

angular-base64

Encapsulation of Nick Galbreath's base64.js library for AngularJS

For Base64 encoding which supports UTF8 see angular-utf8-base64

Installation

Bower

bower install angular-base64

NB: The ngBase64 bower package is deprecated due to camel casing issues on case-sensitive file systems.

<script src="bower_components/angular-base64/angular-base64.js"></script>

Usage

angular
    .module('myApp', ['base64'])
    .controller('myController', [
    
        '$base64', '$scope', 
        function($base64, $scope) {
        
            $scope.encoded = $base64.encode('a string');
            $scope.decoded = $base64.decode('YSBzdHJpbmc=');
    }]);

Unicode

You can encode unicode strings using base64 as described here.

angular
    .module('myApp', ['base64'])
    .controller('myUnicodeController', [
    
        '$base64', '$scope', 
        function($base64, $scope) {
        
            $scope.encoded = $base64.encode(unescape(encodeURIComponent('✓ a string')));
            $scope.decoded = decodeURIComponent(escape($base64.decode('4pyTIGEgc3RyaW5n')));
    }]);

URL Safety

If you want to transmit a base64 encoded string in a url you must make it "URL safe" by encoding it with encodeURIComponent.

var base64EncodedString = $base64.encode('a string');
var urlSafeBase64EncodedString = encodeURIComponent(base64EncodedString);

To decode the above string use decodeURIComponent, then decode.

var base64EncodedString = decodeURIComponent('YSBzdHJpbmc%3D');
var decodedString = $base64.decode(base64EncodedString);
