@aws-sdk/util-utf8-browser

What is @aws-sdk/util-utf8-browser?

The @aws-sdk/util-utf8-browser package is designed for encoding and decoding UTF-8 content in web browsers. It provides utilities to convert between string data and Uint8Array binary format, facilitating the handling of text data in web applications that interact with AWS services or any other use cases requiring UTF-8 encoding/decoding.

What are @aws-sdk/util-utf8-browser's main functionalities?

UTF-8 Encoding

This feature allows you to encode a JavaScript string into a Uint8Array using UTF-8 encoding. It's useful for preparing text data for binary-safe transmission or storage.

const { fromUtf8 } = require('@aws-sdk/util-utf8-browser');
const encodedData = fromUtf8('Hello, world!');

UTF-8 Decoding

This feature enables the decoding of a Uint8Array binary data back into a JavaScript string using UTF-8 decoding. It's essential for converting received binary data into a human-readable format.

const { toUtf8 } = require('@aws-sdk/util-utf8-browser');
const decodedString = toUtf8(new Uint8Array([72, 101, 108, 108, 111]));

Other packages similar to @aws-sdk/util-utf8-browser

text-encoding

The 'text-encoding' package provides a polyfill for the Encoding Living Standard's API, offering encoding and decoding of textual data. It covers a broader range of encodings compared to @aws-sdk/util-utf8-browser, which focuses specifically on UTF-8.

buffer

The 'buffer' package is a node.js library for binary data manipulation that can be used in browsers. It includes methods for encoding and decoding strings in various character encodings, including UTF-8. It offers more general-purpose binary data handling capabilities compared to the more focused UTF-8 encoding/decoding functionality of @aws-sdk/util-utf8-browser.
