Similar to urlsafe-base64 this library de-/encodes urlsafe base64 strings.

What it does different:

• Offers a safe and short variant with the short variant being same as urlsafe-base64 and the safe variant keeping the ending = characters making it compatible with other implementations such as python.
• Comes with typescript definitions.
• Uses Buffer.from as new Buffer has been deprecated for a long time.

import { short, safe } from '@tradle/urlsafe-base64'

;[ short, safe ].forEach(variant => {
  const base64Str = short.encode('hello')

  const decoded = short.decode(base64Str)
  const original = decoded.toString()
})
