@aws-sdk/util-base64

What is @aws-sdk/util-base64?

@aws-sdk/util-base64 is a utility package provided by AWS SDK for JavaScript. It offers functions to encode and decode Base64 strings, which are commonly used in data encoding and transmission.

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

Base64 Encoding

This feature allows you to encode a string into Base64 format. The `toBase64` function takes a string as input and returns its Base64 encoded version.

const { toBase64 } = require('@aws-sdk/util-base64');
const data = 'Hello, World!';
const encodedData = toBase64(data);
console.log(encodedData); // Outputs: 'SGVsbG8sIFdvcmxkIQ=='

Base64 Decoding

This feature allows you to decode a Base64 encoded string back to its original format. The `fromBase64` function takes a Base64 encoded string as input and returns the decoded string.

const { fromBase64 } = require('@aws-sdk/util-base64');
const encodedData = 'SGVsbG8sIFdvcmxkIQ==';
const decodedData = fromBase64(encodedData);
console.log(decodedData); // Outputs: 'Hello, World!'

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

base64-js

The `base64-js` package provides utilities for encoding and decoding Base64 strings. It is a lightweight and efficient library that offers similar functionalities to @aws-sdk/util-base64, but it is not tied to AWS SDK.

js-base64

The `js-base64` package is another popular library for Base64 encoding and decoding. It offers a simple API and is widely used in the JavaScript community. It provides similar functionalities to @aws-sdk/util-base64 but is more focused on general use cases.

buffer

The `buffer` package is a part of Node.js core libraries and provides a way to handle binary data, including Base64 encoding and decoding. It is more versatile and can handle various binary data manipulations, making it a more comprehensive solution compared to @aws-sdk/util-base64.
