# Class fields support for Acorn [![NPM version](https://img.shields.io/npm/v/acorn-class-fields.svg)](https://www.npmjs.org/package/acorn-class-fields) This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript. It implements support for class fields as defined in the stage 3 proposal [Class field declarations for JavaScript](https://github.com/tc39/proposal-class-fields). The emitted AST follows [an ESTree proposal](https://github.com/estree/estree/pull/180). ## Usage This module provides a plugin that can be used to extend the Acorn `Parser` class: ```javascript const {Parser} = require('acorn'); const classFields = require('acorn-class-fields'); Parser.extend(classFields).parse('class X { x = 0 }'); ``` ## License This plugin is released under an [MIT License](./LICENSE).
