data-uri-to-buffer

Generate a Buffer instance from a Data URI string

This module accepts a "data" URI String of data, and returns a node.js Buffer instance with the decoded data.

Install with npm:

$ npm install data-uri-to-buffer
var dataUriToBuffer = require('data-uri-to-buffer');
 
// plain-text data is supported 
var uri = 'data:,Hello%2C%20World!';
var decoded = dataUriToBuffer(uri);
console.log(decoded.toString());
// 'Hello, World!' 
 
// base64-encoded data is supported 
uri = 'data:text/plain;base64,SGVsbG8sIFdvcmxkIQ%3D%3D';
decoded = dataUriToBuffer(uri);
console.log(decoded.toString());
// 'Hello, World!' 

The type property on the Buffer instance gets set to the Content-Type portion of the "mediatype" portion of the "data" URI, or defaults to "text/plain" if not specified.

The charset property on the Buffer instance gets set to the Charset portion of the "mediatype" portion of the "data" URI, or defaults to "US-ASCII" if not specified.
