function urlsafe-base64.decode (base64)

• description and source-code

  function decode(base64) {
  
    // Add removed at end '='
    base64 += Array(5 - base64.length % 4).join('=');
  
    base64 = base64
      .replace(/\-/g, '+') // Convert '-' to '+'
      .replace(/\_/g, '/'); // Convert '_' to '/'
  
    return new Buffer(base64, 'base64');
  
  }

• example usage

  ...
        throw err;
        return;
      };
      randomURLSafeBase64 = URLSafeBase64.encode(buf);
    });
  ```
  
  ### .decode(string)
  
  Decodes a URL Safe Base64 string as a buffer.
  
  ``` javascript
  var someURLSafeBase64 = '';
  URLSafeBase64.decode(someURLSafeBase64); // returns a buffer
  ```
  ...

function urlsafe-base64.encode (buffer)

• description and source-code

  function encode(buffer) {
  
    return buffer.toString('base64')
      .replace(/\+/g, '-') // Convert '+' to '-'
      .replace(/\//g, '_') // Convert '/' to '_'
      .replace(/=+$/, ''); // Remove ending '='
  
  }

• example usage

  ...
  
  Require it within your module:
  
  ``` javascript
  var URLSafeBase64 = require('urlsafe-base64');
  ```
  
  ### .encode(buffer)
  
  Encodes a buffer as a URL Safe Base64 string. This function encodes to
  the RFC 4648 Spec where '+' is encoded as '-' and '/' is encoded as '_'.
  The padding character '=' is removed.
  
  ``` javascript
  var randomURLSafeBase64;
  ...

function urlsafe-base64.validate (base64)

• description and source-code

  function validate(base64) {
  
    return /^[A-Za-z0-9\-_]+$/.test(base64);
  
  }

• example usage

  ...

  ``` javascript
  var someURLSafeBase64 = '';
  URLSafeBase64.decode(someURLSafeBase64); // returns a buffer
  ```
  
  ### .validate(string)
  
  Validates a string if it is URL Safe Base64 encoded.
  
  ``` javascript
  var validURLSafeBase64 = '';
  URLSafeBase64.validate(validURLSafeBase64); // returns true
  ...
