I'm fairly new to MERN and we're trying to deploy an app to DigitalOcean with one main domain and 2 subdomain.

we have the following setup for our app.

Three separate repos:

• Api (backend server for reading writing data)
• User (front end for users of our app)
• Admin (back end for admins)

We have 3 domains / subdomains registered in the following format: domain.com (user) admin.domain.com (admin) api.domain.com (api)

Questions:

• How do we setup the droplet to accommodate this configuration? (user and admin side should point to api server)
• How do we deploy to the three separate repos from github to the one droplet while respecting the corresponding domain / subdomains?

Other considerations: Do we need to use Nginx? Pm2? We will be using mongodb as our database.

Thank you!
