Make sure you have NodeJS
Use npm install to install packages.
You need start the application with command npm start. The application will be running at http://localhost:8080 , if you need start on the other port you can change a start command in the package.json file.
For the best start test scenario use command npm run test:best
For typical start test scenario use command npm run test:typical
P.S. You can also run npm run prettier for code formatting
