You can use http-server for doing so. First of all generate a build using the command ng build --prod --aot --output-hashing=none. This will create a dist folder in your directory structure.
After this, run http-server ./dist, which will start serving your project from dist folder.
Make sure you have installed http-server globally using
npm install http-server -g
