How to build the code to one directory when exec 'npm run start'

[TerryChenUI]

Now when I exec command of 'npm run start', it will not build the code to directory.
I want to watch the file and rebuild the code to one directory.
how to config it?

Can you clarify what you are trying to accomplish?
Are you trying to run a single command that both runs the app via npm run start, and builds your app via npm run build? And you also want to retriggering the build when a file changes?

Building the app takes a long time for large apps, so I would not recommend rebuilding everytime there is a file change.

For example,

1. I config a host like this:

127.0.0.1 abc.com

2. I config nginx to direct the UI code dist directory which is compiled by devmode.

So when I change a file, then rebuild to the dist directory, how can it work?

So create-react-app doesn't support rebuilding the app every time a file changes because building takes a long time.
