ParameterTypeDescription
inputstring / ArrayBuffer (≥ v0.31.0)The input string or ArrayBuffer object to base64 encode.
encoding (optional)stringThe base64 encoding to use.
Available options are:
- "std": the standard encoding with = padding chars and + and / characters in encoding alphabet. This is the default.
- "rawstd": like std but without = padding characters.
- "url": URL safe version of std, encoding alphabet doesn't contain + and / characters, but rather - and _ characters.
- "rawurl": like url but without = padding characters.

Returns

TypeDescription
stringThe base64 encoding of the input data.

Example

import { check } from 'k6';
import encoding from 'k6/encoding';


export default function () {
  const str = 'hello world';
  const enc = 'aGVsbG8gd29ybGQ=';
  const buf = new Uint8Array([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]).buffer;
  check(null, {
    'is encoding string correct': () => encoding.b64encode(str) === enc,
    'is encoding ArrayBuffer correct': () => encoding.b64encode(buf) === enc,
  });
}
