Base64 Encoding and Decoding Library

This JavaScript library provides methods to encode and decode strings using Base64 encoding. The library includes functions to handle UTF-8 encoding and decoding to ensure proper encoding of Unicode characters.

Features

Base64 Encoding: Convert a string to its Base64 encoded representation. Base64 Decoding: Convert a Base64 encoded string back to its original representation. UTF-8 Encoding: Convert a string to its UTF-8 encoded representation (internal use). UTF-8 Decoding: Convert a UTF-8 encoded string back to its original representation (internal use).

Usage

Importing the Library

You can import the Base64 library in your JavaScript project:

import { Base64 } from 'str-base64';

Creating an Instance

Create an instance of the Base64 class:

const base64 = new Base64();

Encoding a String

Use the encode method to encode a string to Base64:

const encodedString = base64.encode('Hello, World!');
console.log(encodedString); // Outputs: "SGVsbG8sIFdvcmxkIQ=="

Decoding a String

Use the decode method to decode a Base64 encoded string:

const decodedString = base64.decode('SGVsbG8sIFdvcmxkIQ==');
console.log(decodedString); // Outputs: "Hello, World!"
