MongoDB
4.0 / 5
A document database: data is stored as JSON, in the same shape it has in the code. On this site it underpins authentication and the Laboratorio's live experiments.
MongoDB stores documents in the natural shape of your data: a game of the Laboratorio's role-playing game is a document, with its players inside, not a constellation of tables with joins. For prototyping and for domains that change often, that flexibility is welcome.
On this site it handles authentication and the state of the experiments, with very practical details like TTL indexes: you tell it a game expires in 60 days and Mongo deletes it on its own. Flexibility has its flip side: without schema discipline (here, validation with Zod and types), the database ends up being a box of surprises.
