@aws-sdk/util-base64-node

What is @aws-sdk/util-base64-node?

The @aws-sdk/util-base64-node package is designed for encoding and decoding strings or data using the Base64 encoding scheme specifically in Node.js environments. This is particularly useful when dealing with web data or APIs that require Base64-encoded strings.

What are @aws-sdk/util-base64-node's main functionalities?

Base64 Encoding

This feature allows you to encode plain text into Base64 format. It's useful for encoding data that needs to be safely transmitted over media that are designed to deal with textual data.

const { toBase64 } = require('@aws-sdk/util-base64-node');
const encodedData = toBase64('Hello World');
console.log(encodedData);

Base64 Decoding

This feature enables you to decode Base64 encoded data back into its original string format. It's essential for retrieving the original data from a Base64 encoded string received from web sources or APIs.

const { fromBase64 } = require('@aws-sdk/util-base64-node');
const decodedData = fromBase64('SGVsbG8gV29ybGQ=');
console.log(decodedData);

Other packages similar to @aws-sdk/util-base64-node

base64-js

base64-js is a popular npm package that provides similar Base64 encoding and decoding functionalities. It is lightweight and does not depend on the Buffer class available in Node.js, making it suitable for use in both browser and Node.js environments. This contrasts with @aws-sdk/util-base64-node, which is optimized specifically for Node.js.

js-base64

js-base64 is another widely used package that supports both Base64 encoding and decoding. It works in various JavaScript environments including browsers, Node.js, and React Native. Unlike @aws-sdk/util-base64-node, js-base64 also includes additional capabilities such as handling Unicode strings and Base64URL encoding/decoding.
