The prepares for next-server.
I also took this as an opportunity to get all build directory paths from a single location, as they were previously scattered across webpack/babel plugins and loaders.
* Use without .js for the filename.
* Modify the chunk filename to add .js via webpack
* Add import chunk's hash to the filename via webpack.
* Remove buildId from dynamic import urls.
* Make sure next-export work with dynamic imports
* Propagate source maps through combine assets step
* Use constant development build id
* Move combine assets step before uglify step
This ensures that uglify will catch these changes.
* Move dynamic chunks step before uglify step
This ensures that uglify will catch these changes.
* Use chunk templates for page and dynamic chunks
This is a little more in line with how webpack generates its bootstrap and should have better compatibility with other plugins and source map generation.
* Register combined source map with chunks
This ensures that a sourcemap is fully generated.
* Do not minimize combined map inputs
