b64-to-blob v1.2.19
b64toBlob(b64Data: string, contentType?: string): Blob
converts a base64
string to a Blob object as described in this Stack Overflow post.
Note that the Blob
class only exists in browsers, not Node, so this package
is only meant for use in the browser and simulated browser environments, not as
part of a typical Node server.
Example Usage
This module uses the UMD returnExports pattern to export itself for either AMD or Node/Webpack module loading, falling back to a global browser definition if neither are available.
With Webpack
npm install b64-to-blob
var b64toBlob = require('b64-to-blob');
var contentType = 'image/png';
var b64Data =
'iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACN' +
'byblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHx' +
'gljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==';
var blob = b64toBlob(b64Data, contentType);
var blobUrl = URL.createObjectURL(blob);
window.location = blobUrl;
Without a Build Step
<script src="https://unpkg.com/b64-to-blob"></script>
<script>
var contentType = 'image/png';
var b64Data =
'iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACN' +
'byblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHx' +
'gljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==';
var blob = b64toBlob(b64Data, contentType);
var blobUrl = URL.createObjectURL(blob);
window.location = blobUrl;
</script>
