How do the files generated by webpack watch go into memory like dev server?

for separate projects, webpack dev server will put the js packaged by the development environment into memory and will not generate physical files on the hard disk. For projects that are not separated from each other, you need to use webpack watch for real-time packaging. How can this real-time packaged file be put into memory?
