## 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`.

|
||||
|
||||
## 🚴 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.
|
||||
* `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
|
||||
|
||||
## License
