Sequelize
Sequelize is an Object-Relational Mapping (ORM) library for Node.js that provides a high-level abstraction for interacting with SQL databases. It supports multiple database systems like PostgreSQL, MySQL, SQLite, and MSSQL, allowing developers to define models, perform queries, and handle migrations using JavaScript or TypeScript. By abstracting raw SQL, it simplifies database operations and promotes code maintainability in Node.js applications.
Developers should learn Sequelize when building Node.js applications that require robust database interactions with SQL databases, as it reduces boilerplate SQL code and provides features like model associations, transactions, and migrations. It is particularly useful for projects using Express.js or other Node.js frameworks where consistent data modeling and query building are needed, such as in web APIs, e-commerce platforms, or content management systems.
