How to enable support for class properties in the latest version BabelJS?


Does anyone know how to enable support for properties of a class in the latest version BabelJS?

import React from 'react'; import {Component} from 'react'; export default class Button extends Component { constructor(){ super(); } myProp = {}; // ERROR: /path/to/file/Button.jsx: Unexpected token (9:11) render(){ return <div></div>; } }


With Babel 6, you use the <a href="http://babeljs.io/docs/plugins/syntax-class-properties/" rel="nofollow">syntax-class-properties plugin</a>, by installing it:

npm install babel-plugin-syntax-class-properties

and adding it to your .babelrc:

{ "plugins": ["syntax-class-properties"] }
