dot.wasm

Dot product accelerated by WebAssembly

Quick Start

This quickstart uses vite to quickly scaffold a JavaScript project.

npm create vite@latest    # select the options you want
npm install dot.wasm      # install the library

Now where you want to use the library (in a JS or TS file)

// we need to import it with it's path (the wasm file is not handled properly by vite)
import { init, dot } from "./node_modules/dot.wasm";

Before using the dot function we need to call init to instantiate the WebAssembly module. The dot function takes two ArrayLike objects as its arguments. This can either be JavaScript Arrays or Typed Arrays.

await init();
console.log(
  dot(new Float32Array([1, 2]), new Float32Array([3, 4]))
); // 11

This function throws an error if the two arguments:

1. are of different lengths
2. are of different types
3. are not in the list of supported types
