pg-mem

pg-mem is an in-memory PostgreSQL emulator for Node.js and TypeScript that allows you to simulate a Postgres database without a real server. It’s perfect for unit testing and development scenarios where spinning up a full database would be too heavy. pg-mem supports many Postgres features and is compatible with various ORMs like TypeORM and Sequelize.
