Package description

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);
