For an app with related users, matches, and messages, MongoDB with Mongoose is a popular, flexible choice. For highly relational data with complex joins, consider a SQL database. Choose based on your data shape.
Mongoose gives schemas, validation, and middleware in Node. It prevents bugs by enforcing structure, runs validators before saves, and gives a clear model-based way to interact with MongoDB instead of the raw driver.
