Here's how to use a Browser Sync server with Brunch. Place this file along side `brunch-config.js`, and start Brunch with the `--server` option.

brunch-server.js

const browserSync = require('browser-sync');

module.exports = (port, path, callback) => {
  const browserSyncServer = browserSync.create();
  browserSyncServer.init({
    port,
    serveStatic: [path],
    // Other Browser Sync options go here
  }, callback);
  return {close: () => browserSyncServer.exit()}
};
