data-uri-to-buffer
==================

$3

This module accepts a ["data" URI][rfc] String of data, and returns
an ArrayBuffer instance with the decoded data.

This module is intended to work on a large variety of JavaScript
runtimes, including Node.js and web browsers.

Example
-------

``typescript
import { dataUriToBuffer } from 'data-uri-to-buffer';

// plain-text data is supported
let uri = 'data:,Hello%2C%20World!';
let parsed = dataUriToBuffer(uri);
console.log(new TextDecoder().decode(parsed.buffer));
// 'Hello, World!'

// base64-encoded data is supported
uri = 'data:text/plain;base64,SGVsbG8sIFdvcmxkIQ%3D%3D';
parsed = dataUriToBuffer(uri);
console.log(new TextDecoder().decode(parsed.buffer));
// 'Hello, World!'
`


API
---

`typescript
export interface ParsedDataURI {
type: string;
typeFull: string;
charset: string;
buffer: ArrayBuffer;
}
`

$3

The type property gets set to the main type portion of
the "mediatype" portion of the "data" URI, or defaults to "text/plain" if not
specified.

The typeFull property gets set to the entire
"mediatype" portion of the "data" URI (including all parameters), or defaults
to "text/plain;charset=US-ASCII" if not specified.

The charset property gets set to the Charset portion of
the "mediatype" portion of the "data" URI, or defaults to "US-ASCII" if the
entire type is not specified, or defaults to "" otherwise.

Note: If only the main type is specified but not the charset, e.g.
"data:text/plain,abc"`, the charset is set to the empty string. The spec only
defaults to US-ASCII as charset if the entire type is not specified.
