Bytes-Base64

For converting between Uint8Array and Base64 strings. This library is primarily developed for WeChat Mini Programs and has been verified to work on mini programs.

• Extremely small compressed size
• No dependencies (no need to install Buffer)
• Compatible with Node.js, browser, and WeChat Mini Programs
• Tested with Jest

用于 Uint8Array 和 Base64 字符串的相互转换，此库主要为微信小程序开发，已在小程序上验证。

• 非常小的压缩尺寸
• 没有任何依赖（无需安装 Buffer）
• 兼容 Node.js、浏览器，以及微信小程序
• 通过 Jest 测试

Usage

NPM

npm i bytes-base64

YARN

yarn add bytes-base64

Example

import { bytesToBase64, base64ToBytes } from 'bytes-base64';

test('[1]', () => {
  const base64 = 'SGVsbG8gd29ybGQ=';
  const bytes = base64ToBytes(base64);
  expect(bytes).toEqual(new Uint8Array([72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]));
});

test('[2]', () => {
  const bytes = new Uint8Array([72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]);
  const base64 = bytesToBase64(bytes);
  expect(base64).toBe('SGVsbG8gd29ybGQ=');
});

test('[3]', () => {
  const bytes = base64ToBytes('SGVsbG8gd29ybGQ=');
  const base64 = bytesToBase64(bytes);
  expect(base64).toBe('SGVsbG8gd29ybGQ=');
});

test('[4]', () => {
  const bytes = new Uint8Array([72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]);
  const base64 = bytesToBase64(bytes);
  const decodedBytes = base64ToBytes(base64);
  expect(decodedBytes).toEqual(bytes);
});
