What is @aws-sdk/util-base64-browser?
@aws-sdk/util-base64-browser is a utility package designed for encoding and decoding Base64 strings in browser environments. It is part of the AWS SDK for JavaScript and provides simple functions to handle Base64 operations, which are often needed for encoding binary data as text.
What are @aws-sdk/util-base64-browser's main functionalities?
Base64 Encoding
This feature allows you to encode a string into Base64 format. The `toBase64` function takes a string input and returns its Base64 encoded version.
const { toBase64 } = require('@aws-sdk/util-base64-browser');
const input = 'Hello, World!';
const encoded = toBase64(input);
console.log(encoded); // 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 and returns the decoded string.
const { fromBase64 } = require('@aws-sdk/util-base64-browser');
const encoded = 'SGVsbG8sIFdvcmxkIQ==';
const decoded = fromBase64(encoded);
console.log(decoded); // Outputs: 'Hello, World!'
Other packages similar to @aws-sdk/util-base64-browser
js-base64
The `js-base64` package provides similar functionality for encoding and decoding Base64 strings. It is a lightweight and fast library that works in both Node.js and browser environments. Compared to @aws-sdk/util-base64-browser, `js-base64` is more general-purpose and not tied to the AWS SDK.
base-64
The `base-64` package is another library for Base64 encoding and decoding. It is simple and easy to use, supporting both Node.js and browser environments. Like `js-base64`, it is a standalone package and not part of a larger SDK like @aws-sdk/util-base64-browser.
buffer
The `buffer` package from Node.js provides a `Buffer` class that can be used for Base64 encoding and decoding among other binary data operations. It is more versatile and powerful compared to @aws-sdk/util-base64-browser, but it is also more complex and primarily designed for Node.js environments.
