Readme
This module accepts a "data" URI 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.
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!'
export interface ParsedDataURI {
type: string;
typeFull: string;
charset: string;
buffer: ArrayBuffer;
}
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.
