@webassemblyjs/utf8

What is @webassemblyjs/utf8?

@webassemblyjs/utf8 is a utility package for encoding and decoding UTF-8 strings in the context of WebAssembly. It provides functions to convert between UTF-8 byte arrays and JavaScript strings, which is useful when dealing with WebAssembly text format (WAT) or binary format (WASM).

What are @webassemblyjs/utf8's main functionalities?

Encode a string to UTF-8

This feature allows you to encode a JavaScript string into a UTF-8 byte array. The `encode` function takes a string as input and returns a Uint8Array representing the UTF-8 encoded bytes.

const { encode } = require('@webassemblyjs/utf8');
const utf8Array = encode('Hello, WebAssembly!');
console.log(utf8Array);

Decode a UTF-8 byte array to a string

This feature allows you to decode a UTF-8 byte array back into a JavaScript string. The `decode` function takes a Uint8Array as input and returns the corresponding string.

const { decode } = require('@webassemblyjs/utf8');
const utf8Array = new Uint8Array([72, 101, 108, 108, 111, 44, 32, 87, 101, 98, 65, 115, 115, 101, 109, 98, 108, 121, 33]);
const str = decode(utf8Array);
console.log(str);

Other packages similar to @webassemblyjs/utf8

text-encoding

The `text-encoding` package provides a polyfill for the TextEncoder and TextDecoder APIs, which are used to encode and decode strings to and from various encodings, including UTF-8. It offers similar functionality to @webassemblyjs/utf8 but is more general-purpose and not specifically tailored for WebAssembly.

utf8

The `utf8` package is a well-known library for encoding and decoding UTF-8 strings in JavaScript. It provides similar functionality to @webassemblyjs/utf8 but is more focused on general UTF-8 encoding and decoding rather than being part of a WebAssembly toolchain.
