This will require NPM.
Inside the frontend directory, you can run the following commands:
npm install
This downloads dependencies defined in the project and generates a node_modules folder with the installed dependencies.
npm start
This runs the app in the development mode. Open http://localhost:3000/ to view it in the browser. The page will reload if you make edits. You will also see any lint errors in the console.
npm run build
This builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
