问题
So, I developed a small React application using create-react-app. (I have always made applications from scratch.)
Then, after I was kind of happy with it, I decided to run npm run build to make an optimized production build.
Can someone please tell me how I can run the production build instead of the Dev build?
回答1:
When you run npm run build your console should actually say something like the following
The build folder is ready to be deployed.
You may serve it with a static server:
npm install -g serve
serve -s build
The build script is building your entire app into the build folder, ready to be statically served. However actually serving it require some kind of static file server, like the the one they propose.
After running the command serve -s build you can access your production build at localhost (on the specified port).
You can of course run whatever static file server you like, I usually use express for this, however serve seems like the easiest option to just serve your statics files with a single command.

use this command : npm install -g serve -s build
