HMR not working on /pages for projects named *.github.io

[elmasse]

There is a reported issue with next v7.0.2 (vercel/next.js#5429) that prevents HMR to work with projects that contains .git in the name.
I'm posting this to keep track of the issue resolution and for future reference the quick workaround is to set the webpackDevMiddleware watchOptions as follows using next.config.js:

module.exports = {
  webpackDevMiddleware(config) {
    config.watchOptions = {
      ignored: [
        /\.git\//,
        /\.next\//,
        /node_modules/
      ]
    }
    return config;
  }
}

Fixed on next 7.0.3 / 8.0.0
