|
==================
|
|
### Generate a Buffer instance from a [Data URI][rfc] string
|
|
[](https://travis-ci.org/TooTallNate/node-data-uri-to-buffer)
|
|
|
|
This module accepts a ["data" URI][rfc] String of data, and returns a
|
|
node.js `Buffer` instance with the decoded data.
|
|
|
|
|
|
Installation
|
|
------------
|
|
|
|
Install with `npm`:
|
|
|
|
``` bash
|
|
$ npm install data-uri-to-buffer
|
|
```
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
``` js
|
|
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!'
|
|
```

### dataUriToBuffer(String uri) → Buffer
|
|
|
|
The `type` property on the Buffer instance 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 on the Buffer instance 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 on the Buffer instance 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 the 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.
