## About
|
||||
|
||||
Wasm package for oxc compiler.
|
||||
|
||||
## 🚴 Usage
|
||||
|
||||
```js
|
||||
import oxc from 'oxc-wasm'
|
||||
|
||||
const ast = oxc.main(code, options)
|
||||
```
|
||||
|
||||
### 🛠️ 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.
