cratchit

A Rust-based library for handling accounting data.

Building

There are two methods of building. The first is building natively, which allows you to run tests locally. To build natively, run: cargo build

To build the wasm module, you need to first install the necessary prerequisites: ```

We use nightly rust for a few features

rustup default nightly

Install wasm-pack

curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh

Install the latest npm (if you don't have npm installed, then you'll need

to do this first. It comes with nodejs, so however you want to install nodejs

on your system is probably fine)

npm install npm@latest -g ```

Once the prerequisites are installed, you can run: wasm-pack build

Testing

If you compiled the native code, you can run the unit tests with the command: cargo test

To test the wasm module, we have a very small test application in www. You will need to set it up locally on your machine. To do this, run: ```

First, make sure the wasm package is linked within npm

cd pkg npm link

Now, install npm dependencies and make sure we can see the cratchit wasm

module

cd ../www npm install npm link cratchit ```

You should now be able to run: npm start

within the www subdirectory, which will spawn a webserver at localhost:8080 that you can navigate to within a web browser to test the wasm module.
