    Feature-rich ORM for modern Node.js and TypeScript, it supports PostgreSQL (with JSON and JSONB support), MySQL, MariaDB, SQLite, MS SQL Server, Snowflake, Oracle DB (v6), DB2 and DB2 for IBM i.

    If your application doesn't necessitate raw SQL/NoSQL, opt for Object-Relational Mappers (ORMs) like Sequelize or Object-Document Mappers (ODMs) like Mongoose for database queries. They feature built-in protection against injection attacks, such as parameterized queries, automatic escaping, and schema validation, and adhere to some security best practices.

  • Mongoose

    MongoDB object modeling designed to work in an asynchronous environment.
