@kcuf/base64 v0.1.0

@kcuf/base64

Base64 url-safe encode/decode.

Why

The two Base64 related functions are now widely available in modern browsers:

• btoa for encoding
• atob for decoding

However, btoa does not support Unicode now, any of these will break:

• btoa('中文')
• btoa('💥')

That's why this package is used.

• 不支持 unicode，汉字和 Emoji 等会报错

  • FF → DOMException: String contains an invalid character
  • CH → DOMException: Failed to execute 'atob' on 'Window': The string to be decoded contains characters outside of the Latin1 range.
  • SF → InvalidCharacterError: The string contains invalid characters.

• 这两个方法有些奇怪，可以把它从 window 上脱离出来调用，但不能把它挂到某对象下面调用，否则会报错

  • FF → TypeError: 'atob' called on an object that does not implement interface Window
  • CH → TypeError: Illegal invocation
  • SF → TypeError: Can only call Window.btoa on instances of Window

How to Use

encode

import {
  encode
} from '@kcuf/base64';

encode(stringToEncode);
encode(stringToEncode, true); // url-safe

decode

import {
  decode
} from '@kcuf/base64';

decode(stringEncoded);
