# base64util [](https://travis-ci.com/duzun/base64util) [](https://codecov.io/gh/duzun/base64util)
base64 encode/decode utility for browsers and node.js,
with polyfill and URL friendly format.
Works with multi-byte and utf8 [strings](https://github.com/duzun/string-encode.js#the-theory-of-string-).
## Usage
### Include [`base64`](https://unpkg.com/base64util) the way you like (AMD/CommonJs/script)
```js
// Encodes multi-byte string as utf8 to base64 (common String)
base64.encode('plain') ;
// Decodes to multi-byte string if utf8-encoded as base64
base64.decode('base64');
// same as encode/decode, but instead of "/" and "+" uses "_" and "-" (URL friendly)
base64.urlEncode('plain') ;
base64.urlDecode('base64');
// encode/decode byte-string - 8bit per char - used for binary data
base64.byteEncode('plain') ;
base64.byteDecode('base64');
// Encode byte-string for URL
base64.byteUrlEncode('plain') ;
base64.byteUrlDecode('base64');
```
### Polyfill
```js
if ( typeof atob === 'undefined' ) {
var window.atob = base64._atob;
var window.btoa = base64._btoa;
}
```
or
```js
base64.polyfill(window);
```
### String.prototype methods
```js
// Add String.prototype methods:
bindProto(String.prototype)
'plain'.base64ByteEncode() ;
'base64'.base64ByteDecode();
'plain'.base64Encode() ;
'base64'.base64Decode();
'plain'.base64ByteUrlEncode() ;
'base64'.base64ByteUrlDecode();
'plain'.base64UrlEncode() ;
'base64'.base64UrlDecode();
```
