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.

Features

  • In-memory emulation of PostgreSQL behavior
  • Works with TypeORM, Sequelize, and pg driver
  • Supports most PostgreSQL SQL syntax and features
  • Ideal for fast, isolated unit testing
  • No external dependencies or database server needed
  • Supports schemas, relations, and transactions
