@loxjs/node-base64 is a Node.js module that provides URL-safe Base64 encoding and decoding. It follows the RFC 4648 Spec for Base64 encoding, where '+' is encoded as '-' and '/' is encoded as '_'. Additionally, it can remove padding characters '=' for a more compact representation.

npm install @loxjs/node-base64

Or with yarn:

yarn add @loxjs/node-base64

This module exports three main functions: encode, decode, and validate. You can use these functions to handle URL-safe Base64 strings within your Node.js applications.

const base64 = require('@loxjs/node-base64');

// Encode a string to Base64
const encodedString = base64.encode('Hello World!');
console.log(encodedString); // Output: SGVsbG8gV29ybGQh (without padding '=' characters)

const base64 = require('@loxjs/node-base64');

// Encode a string to Base64 and keep padding '=' characters
const encodedStringWithEq = base64.encode('Hello World!', true);
console.log(encodedStringWithEq); // Output: SGVsbG8gV29ybGQh== (with padding '=' characters)

const base64 = require('@loxjs/node-base64');

// Decode a URL Safe Base64 string
const decodedString = base64.decode('SGVsbG8gV29ybGQh');
console.log(decodedString); // Output: Hello World!

const base64 = require('@loxjs/node-base64');

// Validate a URL Safe Base64 string
const isValid = base64.validate('SGVsbG8gV29ybGQh');
console.log(isValid); // Output: true

Encodes a buffer or string to URL Safe Base64.

• str (String|Buffer): The string or buffer to encode.
• witheq (Boolean): Optional. If true, retains padding '=' characters. Defaults to false.

Decodes a URL Safe Base64 string to its original representation.

• str (String): The URL Safe Base64 string to decode.

Validates whether a string is a URL Safe Base64 encoded string.

• str (String): The string to validate.
