## README

# acorn-node

[Acorn](https://github.com/acornjs/acorn) preloaded with plugins for syntax parity with recent Node versions.

It also includes versions of the plugins compiled with [Bublé](https://github.com/rich-harris/buble), so they can be run on old Node versions (0.6 and up).

## Install

```
npm install acorn-node
```

## Usage

```js
var acorn = require('acorn-node')
```

The API is the same as [acorn](https://github.com/acornjs/acorn), but the following syntax features are enabled by default:

 - Bigint syntax `10n`
 - Numeric separators syntax `10_000`
 - Public and private class instance fields
 - Public and private class static fields
 - Dynamic `import()`
 - The `import.meta` property
 - `export * as ns from` syntax

And the following options have different defaults from acorn, to match Node modules:

 - `ecmaVersion: 2019`
 - `allowHashBang: true`
 - `allowReturnOutsideFunction: true`

```js
var walk = require('acorn-node/walk')
```

The Acorn syntax tree walker. Comes preconfigured for the syntax plugins if necessary.
See the [acorn documentation](https://github.com/acornjs/acorn#distwalkjs) for details.
