Watching? #5

It would be awesome if changes made in transpiled packages were to cause the same automatic reloading as files changed within the /pages directory. It appears this case is considered in the plugin implementation, and has been iterated on in recent changes, but it is not working for me.

I have a reproduction case here: curran/nextjs-esm-example#4

Reproduction specifics:

• Uses NextJS 7
• Uses Lerna (symlinks)
• Uses an Express app that invokes Next

Desired behavior:

• The NextJS dev server should reload when you change files in the transpiled package.

Current behavior:

• The NextJS dev server does not reload when you change files in the transpiled package (but it does reload if you change files locally).

I notice there's already something going on with watchOptions at https://github.com/martpie/next-plugin-transpile-modules/blob/master/index.js#L59, but I don't know enough about Webpack to assess why the reloading would not be working here.

I can confirm the webpackDevMiddleware is in fact getting set up, and the regex has been replaced.

console.log(ignored); from within the plugin yields the following:

[ /\.git/,
  /\.next\//,
  /node_modules(?!\/(some-es6-package)(?!.*node_modules))/ ]

Still, when I change a file inside /node_modules/some-es6-package/, the watcher does not catch the change.

P. S. Thanks for maintaining this plugin! It's super useful.
