If you want to run frontend(React) and backend(Node) at the same time install concurrently and nodemon.

npm i concurrently 
npm install -g nodemon

then at the package.json file add concurrently to run both frontend and backend together.

"scripts": {
    "start": "node server/index.js",
    "backend": "nodemon server/index.js",
    "frontend": "npm run start --prefix client",
    "dev": "concurrently \"npm run backend\" \"npm run start --prefix client\""
  },

If you want to run only your frontend go to client folder and open your terminal and type

npm start or yarn start
