Convert a Base64-encoded string to a Uint8Array.
npm install @stdlib/string-base-base64-to-uint8arrayWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Convert a Base64-encoded string to a [Uint8Array][@stdlib/array/uint8].
``bash`
npm install @stdlib/string-base-base64-to-uint8array
`javascript`
var base64ToUint8Array = require( '@stdlib/string-base-base64-to-uint8array' );
#### base64ToUint8Array( str )
Converts a base64-encoded string to a [Uint8Array][@stdlib/array/uint8].
`javascript
var string2buffer = require( '@stdlib/buffer-from-string' );
var str = string2buffer( 'Hello World!' ).toString( 'base64' );
// returns 'SGVsbG8gV29ybGQh'
var out = base64ToUint8Array( str );
// returns
`
- The function returns null when provided a string containing non-ASCII characters.
`javascript
var string2buffer = require( '@stdlib/buffer-from-string' );
var base64ToUint8Array = require( '@stdlib/string-base-base64-to-uint8array' );
var buf = string2buffer( 'Hello World!' ).toString( 'base64' );
// returns 'SGVsbG8gV29ybGQh'
var arr = base64ToUint8Array( buf );
// returns
buf = string2buffer( 'HELLO WORLD!' ).toString( 'base64' );
// returns 'SEVMTE8gV09STEQh'
arr = base64ToUint8Array( buf );
// returns
buf = string2buffer( 'To be, or not to be: that is the question.' ).toString( 'base64' );
// returns 'VG8gYmUsIG9yIG5vdCB0byBiZTogdGhhdCBpcyB0aGUgcXVlc3Rpb24u'
arr = base64ToUint8Array( buf );
// returns
