Base 64

A simple Base64 library create as a programming excersise.

There are many much better libraries out there, so use this one only if you would like to play with the code.

Features

• Written in Typescript
• Can decode and encode string from/to Base64 and Base64Url.

Installation

npm i @obsessiveo/base64

Usage

Base64

To encode a string use

const s = base64Encode(text);

This will encode text to a Base64 string and adds padding (=) if needed. It is assumed text is in UTF-8 format.

// for example
const s = base64Encode('Hello World');

To decode a Base64 string use

const s = base64Decode('text');

This will decode text Base64 string

// for example
const s = base64Decode('SGFwcHkgZmFjZQ==');

Base64Url

To encode a string use

const s = base64UrlEncode(text);

This will encode text to a Base64Url string. It is assumed text is in UTF-8 format. Padding is not added.

// for example
const s = base64UrlEncode('Hello World');

results in SGVsbG8gV29ybGQ

To decode a Base64Url string use

const s = base64UrlDecode('text');

This will decode text Base64Url string

// for example
const s = base64UrlDecode('SGFwcHkgZmFjZQ');

results in Happy face
