如何在 create-react-app 中关闭生产构建并使用开发模式？

Question

First I have an app running in development mode, then I created a production build using:

yarn run build

And then served it by using:

serve -s build

Everything was working fine. But now I want to go back to development mode. How it can be done?

Answer 1

First delete the production code, which is build folder. if you're running Linux, Mac Os, so run the below command in the project directory,

rm -rf build

and now start the development server

yarn run start or npm run start
