Additional information

According to the documentation it is possible to write the manifest to disk while using hot module replacement. It does not explain anything about how to do this though.

Please update the documentation to show how this can be done.

The compiler ensures that module IDs and chunk IDs are consistent between these builds. It typically stores these IDs in memory (e.g. with webpack-dev-server), but it's also possible to store them in a JSON file.
