## README

# Astro Compiler

Astro's compiler, written in Rust with [NAPI-RS](https://napi.rs/) bindings for Node.js.

## Install

```
npm install @astrojs/compiler-rs
```

## Usage

#### Transform `.astro` to JavaScript

The Astro compiler transforms `.astro` component files into JavaScript modules whose default export generates HTML.

```js
import { transform } from "@astrojs/compiler-rs";

const result = transform(source, {
  filename: "/Users/astro/Code/project/src/pages/index.astro",
  sourcemap: "both",
});
```

#### Parse `.astro` and return an AST

The compiler can emit an ESTree-compatible AST using the `parse` method.

```js
import { parse } from "@astrojs/compiler-rs";

const result = parse(source);

console.log(JSON.stringify(result.ast, null, 2));
```
