We’re using Prisma (
https://prisma.io) schemas for a particular data exchange project we’re doing so that we can generate JSON schemas, SQLite schemas, PostgreSQL schemas, etc. We have even found a generator to create basic Elixir code from the Prisma schemas.
We’re not using anything else from Prisma, but if we had to implement something else in JS to talk to a database, that would be a contender for our database interface layer (there are only a couple of others that are even remotely usable, having suffered through the disaster of a Sequelize implementation). We’re more likely to use Elixir and Ecto.
