wasm-on-server-runtime-rust

This repository is part of the "Execute untrusted customer code on the server with Web Assembly (Wasm) components" blog post.

It contains a web server that exposes a POST endpoint at http://127.0.0.1:8080/run. The request payload is a WebAssembly component binary which will be executed in a Rust WebAssembly engine.

The Wasm Interface Type (WIT) used by this engine can be found at ./wit/world.wit.

To look at examples of how to create a WebAssembly component for this engine:

• github.com/mootoday/wasm-on-server-guest-rust
• github.com/mootoday/wasm-on-server-guest-javascript

For guides to write Wasm components in other languages, please refer to the official docs.

Getting started

1. Install Devbox

   curl -fsSL https://get.jetify.com/devbox | bash
   

2. Run the web server

   devbox run dev
   

3. Build and deploy either a Rust or Javascript Wasm component.
