Wagi-Ruby

Demo of executing a ruby script in Wagi

Running the demo

Ruby files are placed in './lib' directory.

Run make serve to start wagi.

$ curl 'http://localhost:3000'

The 'ruby-wasm32-wasi/usr' is mounted to '/usr' to allow use of default gems. (base64, pp, etc...)

Running the demo on spin

Run make serve-spin

$ curl 'http://localhost:3000'

Adding gems

$ GEM_HOME=${PWD}/.gem gem install awesome_print

Building Ruby for wasi at home

Follow the Ruby wasm build docs

NOTE: If you're building on arm you must use an arm build of binaryen. I used the latest version.

Copy the Ruby build to the project directory

$ cp [ruby source dir]/ruby-wasm32-wasi .

Rename the ruby binary.

cp ./ruby-wasm32-wasi/usr/local/bin/ruby ./ruby.wasm

Bindle will only set the media type to 'application/wasm' if the file extension is '.wasm'.
