Introduction

This is a step-by-step tutorial to demonstrate how to run computations expressed with orx-parallel’s parallel iterators in a threaded WebAssembly browser app.

The project has three parts:

1. computation/ contains ordinary Rust code and tests.
2. wasm_bindings/ exposes the Rust functions to JavaScript.
3. app/ contains the HTML, CSS, TypeScript, and Vite configuration. TypeScript client calls parallel computations through a worker.

The app starts one shared thread pool. threads: 0 lets the runtime choose the available capacity. Each computation also receives a thread count: 0 uses all initialized threads, while a positive value limits that computation.

Prerequisites

Install Rust and Cargo, Node.js and npm, and the wasm32-unknown-unknown Rust target:

rustup target add wasm32-unknown-unknown

Get started

Create your example application’s directory

mkdir par_wasm
cd par_wasm
