BigInt support for Acorn

This is a plugin for Acorn - a tiny, fast JavaScript parser, written completely in JavaScript.

It implements support for arbitrary precision integers as defined in the stage 4 proposal BigInt: Arbitrary precision integers in JavaScript. The emitted AST follows ESTree.

Usage

This module provides a plugin that can be used to extend the Acorn Parser class:

const {Parser} = require('acorn');
const bigInt = require('acorn-bigint');
Parser.extend(bigInt).parse('100n');
