Base64

This package helps you work with Base64 encoding, providing a similar interface as in elm/bytes and elm/json

Demo

Why another Base64 library?

• Supports Elm 0.19
• Insensitive to padding (as atob/btoa in JS)
• Functional implementation
• Supports raw bytes encoding/decoding
• There is elm/bytes under the hood, so less errors will occur during validations
• Interface is consistent with an Elm's encoders/decoders interface

Usage

The package lets you create encoders and decoders to work with strings and bytes.

Converting a string into a Base64 string:

import Bytes.Encode
import Base64.Encode as Encode


input =
    "Example input string"

encoded =
    Encode.encode (Encode.string input)

Encoding a bytes seqeunce:

import Bytes.Encode
import Base64.Decode as Decode
import Base64.Encode as Encode

stringAsBytes = 
    Bytes.Encode.encode (Bytes.Encode.string "H💩la!")

encoded =
    Encode.encode (Encode.bytes stringAsBytes)

decoded =
    Decode.decode Decode.string encoded

Or you can decode string into raw bytes with Base64.Decode.bytes:

import Base64.Decode as Decode
import Bytes
import Bytes.Decode

-- decodedAsBytes = Decode.decode Decode.bytes someInput
decodedAsString =
    Bytes.Decode.decode (Bytes.Decode.string (Bytes.width decodedAsBytes)) decodedAsBytes
