base64ToUint8Array

Convert a Base64-encoded string to a Uint8Array.

Usage

var base64ToUint8Array = require( '@stdlib/string/base/base64-to-uint8array' );

base64ToUint8Array( str )

Converts a base64-encoded string to a Uint8Array.

var string2buffer = require( '@stdlib/buffer/from-string' );

var str = string2buffer( 'Hello World!' ).toString( 'base64' );
// returns 'SGVsbG8gV29ybGQh'

var out = base64ToUint8Array( str );
// returns <Uint8Array>[ 72, 101, ... ]

Notes

The function returns null when provided a string containing non-ASCII characters.

Examples

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 <Uint8Array>

buf = string2buffer( 'HELLO WORLD!' ).toString( 'base64' );
// returns 'SEVMTE8gV09STEQh'

arr = base64ToUint8Array( buf );
// returns <Uint8Array>

buf = string2buffer( 'To be, or not to be: that is the question.' ).toString( 'base64' );
// returns 'VG8gYmUsIG9yIG5vdCB0byBiZTogdGhhdCBpcyB0aGUgcXVlc3Rpb24u'

arr = base64ToUint8Array( buf );
// returns <Uint8Array>
