@aws-sdk/util-utf8-node

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

The @aws-sdk/util-utf8-node package is designed for encoding and decoding UTF-8 content specifically in Node.js environments. It provides utilities to convert strings to UTF-8 byte arrays and vice versa, which is particularly useful when working with AWS SDKs that require such transformations for handling text in various AWS services.

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

UTF-8 Encoding

Converts a JavaScript string to a UTF-8 encoded byte array. This is useful for preparing data for transmission or storage in formats that require UTF-8 encoding.

"const { fromUtf8 } = require('@aws-sdk/util-utf8-node');
const utf8EncodedString = fromUtf8('Hello World');"

UTF-8 Decoding

Converts a UTF-8 encoded byte array back into a JavaScript string. This is useful for reading data that was stored or transmitted as UTF-8 encoded bytes.

"const { toUtf8 } = require('@aws-sdk/util-utf8-node');
const decodedString = toUtf8(utf8EncodedString);"

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

text-encoding

The 'text-encoding' package provides a polyfill for the Encoding Living Standard's API, offering broader encoding and decoding capabilities beyond UTF-8, including legacy encodings. It's more versatile than @aws-sdk/util-utf8-node but might be overkill for applications only needing UTF-8 support.

iconv-lite

This package offers conversion between various character encodings, including UTF-8, in Node.js. Unlike @aws-sdk/util-utf8-node, which is focused on UTF-8 and designed for AWS SDK usage, iconv-lite supports a wide range of encodings, making it suitable for applications requiring conversion between various character sets.
