How can I encode and decode a base64 string using AngularJS1 and TypeScript?

I am currently working with Angular1 using TypeScript and I have a question that needs some clarification.

Within the environment that I am operating in, is there a method available to encode and decode a string in base64?

Despite conducting extensive research, the only solution I came across was this one. However, I am uncertain if it comes with the necessary Type-definition support.

Answer №1

After taking inspiration from this GitHub repository, I decided to add some TypeScript flavor to it:

angular
    .module('myApp', ['base64'])
    .controller('myController', [

        '$base64', '$scope', 
        function($base64: any, $scope : ng.IScope) {

            $scope.encoded = $base64.encode('a string');
            $scope.decoded = $base64.decode('YSBzdHJpbmc=');
    }]);

In this code snippet, I've simply specified the type of $base64 as "any", allowing for using regular JavaScript without TypeScript errors. While you won't have IntelliSense or type checking with this approach, in certain scenarios it may not be necessary. However, if you prefer defining your own interface for better typing, you can do so like this:

interface Base64Encode {
    encode: (source: string) => string;  
    decode: (encoded: string) => string;
}
