Module parse failed: es6 react component with JSX inside .JS file

Question

Webpack Babel loader fails when importing an es6 react component with .js as the filename extension. If the filename extension is changed to .jsx babel compiles properly. Any clue?

var config = {
  entry : {
    "login" : PAGE_DIR + '/login/index.js',
    "app" : PAGE_DIR + '/app/index.js'
  },
  output: {
    path: BUILD_DIR,
    filename: '[name]-bundle.js'
  },
  module : {
		rules : [
    	{
        test : /\.(js|jsx)$/,
        include : PAGE_DIR,
				exclude: [
				  path.resolve(__dirname, "node_modules"),
				],
        loaders : ['babel-loader']
      }
		]
  }
};

EDIT:

I finally figured it out. I had made a mistake by adding an include folder. My components resided outside the include folder and all these components were not getting parsed with the loader. What I found is webpack only parse files which matches the test pattern and is also inside the include folder.

var webpack = require('webpack');
var path = require('path');

var BUILD_DIR = path.resolve(__dirname, 'client/assets/js');
var APP_DIR = path.resolve(__dirname, 'app/');

var config = {
  entry : {
    "login" : APP_DIR + '/pages/login/index.js',
    "app" : APP_DIR + '/pages/app/index.js'
  },
  output: {
    path: BUILD_DIR,
    filename: '[name]-bundle.js'
  },
  module : {
    loaders : [
      {
        test : /\.jsx?/,
        include : APP_DIR,
        loader : 'babel-loader'
      }
    ]
  }
};

module.exports = config;
