Base64It

A simple base64 encoder/decoder that works with modern browsers, legacy browsers, and Node. It supports strict mode, URL safe encoding/decoding, and optional line lengths.

Get the package

npm install base64it --save

##Encoding

base64it supports the following encoding standards:

1. Standard 'base64' (i.e. strict) (see RFC 4648 § 4)
2. Standard 'base64url' with URL and Filename Safe Alphabet (see RFC 4648 § 5)

Examples

To encode, just call base64.encode.

var base64 = require("base64it");

var encoded = base64.encode("Hello world")
console.log(encoded); // SGVsbG8gd29ybGQ=

To convert it back, just call base64.decode.

var decoded = base64.decode(encoded)
console.log(decoded); // Hello world

API

base64.encode(unencoded:string, options?:Options):string

Encodes a string into a base64 encoded string.

Where:
unencoded is the string you want to encode.
options is a set of encoding Options as follows (optional)

• stripPadding:Boolean - determines whether the resulting string will have any padding characters (i.e. "=") removed (default = false)
• lineLength:Number - if set, the resulting string will be broken into multiple lines seperated by \r\n. This is normally set to either 64 or 76. (default = one continuous line)
• urlSafe:Boolean - if set, the resulting string will be URL Safe (i.e. "+" and "/" chars willbe converted to "-" and "_" respectively). (default = false)

base64.decode(encoded:string):string

This will decode a base64 encoded string. Padding characters are optional.

base64.strictEncode(unencoded:string, options?:Options):string

This is simply sugar around base64.encode with the urlSafe options seto to false.

base64.urlSafeEncode(unencoded:string, options?:Options):string

This is simply sugar around base64.encode with the urlSafe options seto to true.

base64.strictDecode(encoded:string):string

This is the same as base64.decode.

base64.urlSafeDecode(encoded:string):string

This is the same as base64.decode.
