=================

Make Fermyon Spin WebAssembly Modules run on NGINX Unit.

The repository will contain some exploratory tools.

Quickstart
==========

Clone the spin repository

$ git clone https://github.com/fermyon/spin.git

Build the wasm module.

$ cd spin/examples/wasi-http-rust
$ cargo build --target wasm32-wasi

Grab the Wasmtime C API

$ wget -O- https://github.com/bytecodealliance/wasmtime/releases/download/v13.0.0/wasmtime-v13.0.0-x86_64-linux-c-api.tar.xz | tar -xvf -

Clone this repository

$ git clone git://git.digital-domain.net/project_blackbird.git

Build it

$ cd project_blackbird
$ make WASMTIME_C_API=/path/to/wasmtime-c-api WASM_MODULE=/path/to/spin/examples/wasi-http-rust/target/wasm32-wasi/debug/wasi_http_rust.wasm

Run it

$ ./wasmtime-wasi-http
