Readme

babel-plugin-parser-opts
Pass arbitrary Babylon parser options to Babel.
Babel internally uses Babylon to parse JavaScript. However, it does not expose all of Babylon's options to be changed by users. This plugin makes it possible to change all of these options.

Installation

$ npm install babel-plugin-parser-opts

Usage

Via .babelrc

.babelrc
{
  "plugins": [
    [ "parser-opts", { "allowReturnOutsideFunction": true } ]
  ]
}

Via Node API

require('babel-core').transform('code', {
  plugins: [
    [ 'parser-opts', { allowReturnOutsideFunction: true } ]
  ]
});

Parser plugins
