| # 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. | |
