@webassemblyjs/helper-buffer

What is @webassemblyjs/helper-buffer?

@webassemblyjs/helper-buffer is a utility package designed to assist with buffer operations in the context of WebAssembly. It provides functions to manipulate and interact with buffers, which are essential when dealing with WebAssembly binary data.

What are @webassemblyjs/helper-buffer's main functionalities?

createBuffer

The `createBuffer` function allows you to create a new buffer of a specified size. This is useful when you need to allocate memory for WebAssembly operations.

const { createBuffer } = require('@webassemblyjs/helper-buffer');
const buffer = createBuffer(10); // Creates a buffer of 10 bytes
console.log(buffer);

concatUint8Array

The `concatUint8Array` function concatenates two Uint8Array buffers into a single buffer. This is particularly useful when you need to merge multiple binary data chunks.

const { concatUint8Array } = require('@webassemblyjs/helper-buffer');
const buffer1 = new Uint8Array([1, 2, 3]);
const buffer2 = new Uint8Array([4, 5, 6]);
const concatenatedBuffer = concatUint8Array(buffer1, buffer2);
console.log(concatenatedBuffer);

allocBuffer

The `allocBuffer` function allocates a buffer of a specified size, similar to `createBuffer`, but it may have different internal handling or optimizations.

const { allocBuffer } = require('@webassemblyjs/helper-buffer');
const buffer = allocBuffer(10); // Allocates a buffer of 10 bytes
console.log(buffer);

Other packages similar to @webassemblyjs/helper-buffer

buffer

The `buffer` package from Node.js provides a way of handling binary data directly in JavaScript. It is a core module in Node.js and offers a wide range of functionalities for buffer manipulation, making it a more comprehensive solution compared to @webassemblyjs/helper-buffer.

typedarray

The `typedarray` package provides a polyfill for the TypedArray API in JavaScript. It allows for the creation and manipulation of typed arrays, which are similar to buffers. While it offers broader support for different types of arrays, it may not be as specialized for WebAssembly as @webassemblyjs/helper-buffer.

arraybuffer-slice

The `arraybuffer-slice` package provides a method to slice ArrayBuffers, which is a common operation when dealing with binary data. While it focuses on a specific functionality, it can be used in conjunction with other buffer manipulation libraries to achieve similar results as @webassemblyjs/helper-buffer.
