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?

Navigate inside the directory of your app first. According to the official create-react-app website. When you run npm run build or yarn build you create a build directory with a production build of your app.
Npm-build. The npm build is used to build a package, the synopsis is given in the next section. Synopsis npm build [<package-folder>] where <package-folder> is a folder that contains a package. json in its root.
First, go to the package. json file and change the version of react , react-dom , and react-scripts to the desired version. Next, clear the node_modules and the package-lock. json file.
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.

Also you can use "serve" tool, using "npx". in this case no need to install it globally.
npx serve -s build
Navigate inside the directory of your app first.
According to the official create-react-app website. When you run npm run build you create a build directory with a production build of your app.
After running the command above the next thing you can do to check the build version of your app is to to install serve to serve your status site on the port 5000 by default.
npm install -g serve
serve -s build
This will copy the link to your clipboard that you can paste in your browser and see the build version of you app.

First of all run
npm install -g serve
It will install globally the serve, and then execute
serve -s build
You've to first install serve package globally.
If you're using yarn, run this command to do so: yarn global add serve.
For npm: npm install -g serve
And then execute:
serve -s build
