Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
The base64url npm package provides utilities for encoding and decoding data in base64url format, which is a URL-safe variant of base64. It is commonly used to encode data in a way that can be safely transmitted over URLs without encoding issues.
Encoding to base64url
This feature allows you to encode a string or buffer into base64url format. The provided code sample demonstrates how to encode the string 'Hello World!' using the base64url package.
"use strict"; const base64url = require('base64url'); const encoded = base64url('Hello World!'); console.log(encoded);
Decoding from base64url
This feature enables you to decode a base64url encoded string back into its original form. The code sample shows how to decode the string 'SGVsbG8gV29ybGQh' back to 'Hello World!'.
"use strict"; const base64url = require('base64url'); const decoded = base64url.decode('SGVsbG8gV29ybGQh'); console.log(decoded);
From base64 to base64url
This feature allows you to convert a base64 encoded string to a base64url encoded string. The code sample illustrates converting a base64 string 'SGVsbG8gV29ybGQh==' to base64url format.
"use strict"; const base64url = require('base64url'); const base64 = 'SGVsbG8gV29ybGQh=='; const base64urlString = base64url.fromBase64(base64); console.log(base64urlString);
To base64 from base64url
This feature converts a base64url encoded string back to a standard base64 encoded string. The code sample demonstrates converting 'SGVsbG8gV29ybGQh' from base64url to regular base64.
"use strict"; const base64url = require('base64url'); const base64urlString = 'SGVsbG8gV29ybGQh'; const base64 = base64url.toBase64(base64urlString); console.log(base64);
js-base64 is a robust base64 encoder/decoder that is fully compatible with `atob()` and `btoa()`, built to work in both browser and Node.js environments. It offers similar functionality to base64url but does not focus specifically on URL-safe encoding.
base64-js is a package that provides functions to encode and decode base64 data. It is similar to base64url but does not inherently provide URL-safe encoding, which means it might require additional steps to handle URL encoding.
urlsafe-base64 is a package that offers encoding and decoding functions specifically designed to be safe for use in URLs, similar to base64url. It provides a straightforward API for handling base64 encoding with URL safety in mind.
For turning strings or buffers into base64url encoded strings. It can also convert base64url to regular base64.
$ npm install base64url
const base64url = require('base64url');
const data = "I am a teapot hear me roar";
const encoded = base64url(data);
// convert from base64url to regular ol' base64
const b64 = base64url.toBase64(encoded);
// convert from base64 to base64url
const b64url = base64url.fromBase64(b64)
// decode base64url
data === base64url.decode(encoded);
