Ability to update public directory without rebuilding CSS/JS

[iaseth]

I have a project where a big part of the api consists of static json files inside the public directory. The json files are updated or added every few minutes and the project is rebuilt and redeployed. Running npm run build is not needed/practical because the code is not changing and it takes too long. So currently I just do this:

cp -r public/* dist/

It would be great if there was a command/flag like npm run build --update-public-directory that updates the public dir inside dist without rebuilding the codebase.
