create-react-app npm run start in production mode. Maybe not possible?

Question

I need to run the server like I simply do with:

npm run start

but I need to use the production mode. Is this possible?

In ember or angular it is possible. How to do in create-react-app?

I tried npm run start --prod but nothing.

Solution 1

The best option is probably to do a normal production build and then run it locally.
First install an HTTP server:

npm install serve -g

Then:

npm run build
serve -s build

By default, it will run on port 5000 so your local URL is http://localhost:5000

Solution 2

To serve the app in production mode you need to follow below steps

1. create a production build

   npm run build

2. install npm serve globally

   npm i -g serve

3. You may serve it with a static server now

   serve -s build

For the development in production you can enable Hot reloading in react app without ejecting

With just 3 lines of code, you can turn on HMR, but with one big caveat: React state and DOM state are not preserved between reloads. This is kind of a bummer.

You can add these lines to index.js to turn on standard Webpack HMR that doesn’t preserve state between reloads:

if (module.hot) {
  module.hot.accept();
}
