Package description
The urlsafe-base64 npm package provides utilities for encoding and decoding Base64 strings in a URL-safe manner. This means that the encoded strings are safe to use in URLs without needing additional encoding or escaping.
Encoding
This feature allows you to encode a Buffer into a URL-safe Base64 string. The encoded string can be safely used in URLs.
const urlsafeBase64 = require('urlsafe-base64');
const buffer = Buffer.from('Hello, World!');
const encoded = urlsafeBase64.encode(buffer);
console.log(encoded); // Outputs: 'SGVsbG8sIFdvcmxkIQ'Decoding
This feature allows you to decode a URL-safe Base64 string back into a Buffer. The decoded Buffer can then be converted back to its original string form.
const urlsafeBase64 = require('urlsafe-base64');
const encoded = 'SGVsbG8sIFdvcmxkIQ';
const buffer = urlsafeBase64.decode(encoded);
console.log(buffer.toString()); // Outputs: 'Hello, World!'Validation
This feature allows you to validate whether a given string is a valid URL-safe Base64 encoded string.
const urlsafeBase64 = require('urlsafe-base64');
const encoded = 'SGVsbG8sIFdvcmxkIQ';
const isValid = urlsafeBase64.validate(encoded);
console.log(isValid); // Outputs: trueThe base64url package provides similar functionality for encoding and decoding Base64 strings in a URL-safe manner. It also includes methods for encoding and decoding strings and buffers, and it is widely used in the Node.js community.
The js-base64 package is a robust library for encoding and decoding Base64 strings. It supports both standard and URL-safe Base64 encoding, making it a versatile choice for various use cases.
The base64-js package is a pure JavaScript implementation for encoding and decoding Base64 strings. It is lightweight and efficient, and it supports URL-safe encoding as well.
Readme
URL Safe Base64 util module for Node.js applications
With npm do:
npm install urlsafe-base64
Require it within your module:
var URLSafeBase64 = require('urlsafe-base64');
Encodes a buffer as a URL Safe Base64 string. This function encodes to the RFC 4648 Spec where '+' is encoded as '-' and '/' is encoded as '_'. The padding character '=' is removed.
var randomURLSafeBase64;
crypto.randomBytes(32, function(err, buf) {
if (err) {
throw err;
return;
};
randomURLSafeBase64 = URLSafeBase64.encode(buf);
});
Decodes a URL Safe Base64 string as a buffer.
var someURLSafeBase64 = '';
URLSafeBase64.decode(someURLSafeBase64); // returns a buffer
Validates a string if it is URL Safe Base64 encoded.
var validURLSafeBase64 = '';
URLSafeBase64.validate(validURLSafeBase64); // returns true
var invalidURLSafeBase64 = '/+=='
URLSafeBase64.validate(invalidURLSafeBase64); // returns false
