Two projects on one database, or make an API?

Question

Software design

Now there is a telegram bot that works with the database. I want to make a web version of the same project that will work with the same database, and now I’m thinking how it would be better to do it: use one database for two projects, or make another separate API project, and use endpoints in the web version? (You never know, suddenly in the future you will need another version for mobile phones). What is the best way to do it in terms of architecture?

Answer 1

Usually they write API-frontend (its instances), whose clients are content consumers. Well, behind the API is its own database and caching, if necessary.
