webpack --watch and webpack-dev-server are different.webpack-dev-server provides a browser-accessible server, but does not have the ability to save the product to the file system (see ).It must be webpack --watch in order for it to be saved to the file.

To have your product saved to a file while using webpack-dev-server, you can use write-file-webpack-plugin.
