webpack-add-dependency-plugin
In case you are including files to a webpack build indirectly, i.e. through mini-html-webpack-plugin, then it's likely webpack build process won't be aware of them while you are developing and running the project through webpack-dev-server or a similar solution. webpack-add-dependency-plugin solves this issue by letting you make webpack aware of these files.
Example:
; moduleexports = ... plugins: path: "./templates/page.html" ;
Most likely you'll generate these declarations programmatically using tools like glob and webpack-merge but above should give you idea of the basic API.
