# BigInt support for Acorn
|
|
|
|
[](https://www.npmjs.org/package/acorn-bigint)
|
|
|
|
This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.
|
|
|
|
It implements support for arbitrary precision integers as defined in the stage 3 proposal [BigInt: Arbitrary precision integers in JavaScript](https://github.com/tc39/proposal-bigint). The emitted AST follows [an ESTree proposal](https://github.com/estree/estree/blob/132be9b9ec376adbc082dd5f6ba78aefd7a1a864/experimental/bigint.md).
|
|
|
|
## Usage
|
|
|
|
This module provides a plugin that can be used to extend the Acorn `Parser` class:
|
|
|
|
```javascript
|
|
const {Parser} = require('acorn');
|
|
const bigInt = require('acorn-bigint');
|
|
Parser.extend(bigInt).parse('100n');
|
|
```
