Package description
The data-uri-to-buffer npm package is designed to convert Data URIs into Buffers. This is particularly useful when dealing with inline data within web applications, where you might need to handle the data as a binary stream for file operations, uploads, or other processing tasks.
Convert Data URI to Buffer
This feature allows you to convert a Data URI string into a Node.js Buffer. The resulting Buffer can then be used for various binary data operations.
const dataUriToBuffer = require('data-uri-to-buffer');
const dataUri = 'data:text/plain;base64,SGVsbG8sIFdvcmxkIQ==';
const buffer = dataUriToBuffer(dataUri);
console.log(buffer.toString()); // 'Hello, World!'This package offers similar functionality to data-uri-to-buffer by converting Data URI strings to Buffers. It might differ in API design or additional options provided.
While not specifically for Data URIs, this package converts Base64 encoded strings to Buffers. It serves a similar purpose for the subset of Data URIs that are Base64 encoded.
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.
