First, setup the .env file:
MONGODB_URI = 'mongodb+srv://...'
MONGO_DB = 'database'
MONGO_COLLECTION = 'collection'
REDIRECT_URL = 'https://example.com'
IPINFO_TOKEN = '00a0a0a000a0a0'
TITLE = 'Example | Example App'
Then, run the server:
npm i
npm run build
npm run start
Open http://localhost:3000 with your browser to see the result.
The easiest way to deploy the app is to use the Vercel Platform from the creators of Next.js.
