## About
[**📚 Read this template tutorial! 📚**][template-docs]
This template is designed for compiling Rust libraries into WebAssembly and
publishing the resulting package to NPM.
Be sure to check out [other `wasm-pack` tutorials online][tutorials] for other
templates and usages of `wasm-pack`.
[tutorials]: https://rustwasm.github.io/docs/wasm-pack/tutorials/index.html
[template-docs]: https://rustwasm.github.io/docs/wasm-pack/tutorials/npm-browser-packages/index.html
## 🚴 Usage
### 🐑 Use `cargo generate` to Clone this Template
[Learn more about `cargo generate` here.](https://github.com/ashleygwilliams/cargo-generate)
```
cargo generate --git https://github.com/rustwasm/wasm-pack-template.git --name my-project
cd my-project
```
### 🛠️ Build with `wasm-pack build`
```
wasm-pack build
```
### 🔬 Test in Headless Browsers with `wasm-pack test`
```
wasm-pack test --headless --firefox
```
### 🎁 Publish to NPM with `wasm-pack publish`
```
wasm-pack publish
```
## 🔋 Batteries Included
* [`wasm-bindgen`](https://github.com/rustwasm/wasm-bindgen) for communicating
between WebAssembly and JavaScript.
* [`console_error_panic_hook`](https://github.com/rustwasm/console_error_panic_hook)
for logging panic messages to the developer console.
* [`wee_alloc`](https://github.com/rustwasm/wee_alloc), an allocator optimized
for small code size.

## How to install
```sh
npm install
```
## How to run in debug mode
```sh
# Builds the project and opens it in a new browser tab. Auto-reloads when the project changes.
npm start
```
## How to build in release mode
```sh
# Builds the project and places it into the `dist` folder.
npm run build
```
## How to run unit tests
```sh
# Runs tests in Firefox
npm test -- --firefox
# Runs tests in Chrome
npm test -- --chrome
# Runs tests in Safari
npm test -- --safari
```
## What does each file do?
* `Cargo.toml` contains the standard Rust metadata. You put your Rust dependencies in here. You must change this file with your details (name, description, version, authors, categories)
* `package.json` contains the standard npm metadata. You put your JavaScript dependencies in here. You must change this file with your details (author, name, version)
* `webpack.config.js` contains the Webpack configuration. You shouldn't need to change this, unless you have very special needs.
* The `js` folder contains your JavaScript code (`index.js` is used to hook everything into Webpack, you don't need to change it).
* The `src` folder contains your Rust code.
* The `static` folder contains any files that you want copied as-is into the final build. It contains an `index.html` file which loads the `index.js` file.
* The `tests` folder contains your Rust unit tests.
