Specs Wasm Usage Example

This simple example shows the (almost) minimum amount of code currently required to run specs on wasm (in the browser!).

Prerequisites

• Running linux with the standard development tools available for your distribution.
• Rust installed

Getting Started

Clone this repository:

git clone https://github.com/jojolepro/specs_wasm

Make sure that rust nightly is installed and up to date:

rustup install nightly
rustup update

Make nightly the default toolchain:

rustup default nightly

Add the rust-src component:

rustup component add rust-src

Install the wasm-bindgen cli tools:

cargo install -f wasm-bindgen-cli

Install Xargo

cargo install -f xargo

And run the build.sh script!

./build.sh

Open up firefox nightly and navigate to about:config

In there, you want to enable the javascript.options.shared_memory flag.

Once this is done, navigate to http://127.0.0.1:8000 , open the browser console and click the "Run!" button at the top of the page.
