Before
We use MongoDB as our primary database. It provided great performance and versatility, but in combination with Nest.js and GraphQL the overhead in templating and files to create was just too huge.
After
We switched to Prisma.js and Postgres for the reason of great DX. We migrated our data with ease and instantly dropped 100s of schema files off our repository. Also we do not have to deal with cyclic module dependencies when developing our graph api. Its just a pleasure.
