data-uri-to-buffer ================== ### Generate a Buffer instance from a [Data URI][rfc] string [![Build Status](https://travis-ci.org/TooTallNate/node-data-uri-to-buffer.svg?branch=master)](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 import dataUriToBuffer from 'data-uri-to-buffer'; // plain-text data is supported let uri = 'data:,Hello%2C%20World!'; let 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!' ``` API --- ### 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.
