Sequelize vs Entity Framework Core: What are the differences?

Entity Framework Core and Sequelize are popular Object-Relational Mapping (ORM) libraries used in different ecosystems for database management. Entity Framework Core is primarily designed for .NET applications, while Sequelize is intended for Node.js applications. Let's explore the key differences between Entity Framework Core and Sequelize:

  1. Language and Platform: Entity Framework Core is specifically designed for .NET applications, which use C# or other .NET languages. On the other hand, Sequelize is intended for Node.js applications, which use JavaScript or TypeScript. As a result, the usage and integration of these libraries depend on the underlying technology stack of the project.

  2. Ecosystem and Integration: Entity Framework Core seamlessly integrates with other Microsoft technologies and libraries, making it an ideal choice for .NET developers who want a cohesive ecosystem. It works well with ASP.NET Core for building web applications, and it has strong integration with Visual Studio for development. Sequelize, being a Node.js library, naturally integrates with the Node.js ecosystem, including popular frameworks like Express.js. It is also well-suited for projects that follow the JavaScript ecosystem and prefer the simplicity of Node.js.

  3. Data Source Support: Entity Framework Core is known for its extensive support for various database systems, including SQL Server, MySQL, PostgreSQL, SQLite, and more. Additionally, it can connect to NoSQL databases through extensions like EF Core Cosmos DB provider. On the other hand, Sequelize mainly focuses on SQL databases, supporting databases such as MySQL, PostgreSQL, SQLite, and MSSQL. While Sequelize does support some NoSQL databases, its strength lies in handling SQL databases.

  4. Query Syntax: Entity Framework Core follows LINQ (Language Integrated Query) syntax, which allows developers to write database queries using C# or VB.NET code directly in the application codebase. This provides strong typing and compile-time checking, enhancing code readability and maintainability. Sequelize, on the other hand, uses JavaScript-based query syntax that may not offer the same level of type safety as LINQ. However, Sequelize does provide support for Promises and async/await, making it more suitable for asynchronous Node.js applications.

In summary, Entity Framework Core is a robust ORM solution tailored for .NET applications, offering strong integration with the .NET ecosystem and diverse database support. On the other hand, Sequelize is a popular choice for Node.js developers, providing a straightforward and JavaScript-centric approach to handling SQL databases.

What is Entity Framework Core?

It is a lightweight, extensible, open source and cross-platform version of the popular Entity Framework data access technology. It can serve as an object-relational mapper (O/RM), enabling .NET developers to work with a database using .NET objects, and eliminating the need for most of the data-access code they usually need to write.

What is Sequelize?

Sequelize is a promise-based ORM for Node.js and io.js. It supports the dialects PostgreSQL, MySQL, MariaDB, SQLite and MSSQL and features solid transaction support, relations, read replication and more.
