Sequelize VS MikroORM

Sequelize - modern Typescript and NodeJS ORM for Oracle, Postgres, MySQL, MariaDB, SQLite, SQL Server+docs

If you use Sequalize, TypeORM or for MongoDB, we have Mongoose these types of ORM tools, then you are safe by default because these help us against the SQL query injection attacks by default.

Our orders microservice will have its own set of teachnologies just like we earlier plotted that is mysql database and sequelize orm. MySQL is an open-source relational database management system (RDBMS) that is widely used for building web applications and managing data. It is a popular choice for many developers and organizations due to its performance, reliability, and ease of use. Sequelize is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a way to interact with relational databases like MySQL, PostgreSQL, SQLite, and MSSQL using JavaScript or TypeScript. It simplifies database operations by allowing developers to use JavaScript objects to represent database tables and records, instead of writing raw SQL queries. In this microservice, we will use it to query our MySQL database.

However, some ORM operations can’t be translated into a single SQL query that easily. Let’s take Sequelize's findOrInsert. It first sends a SELECT query like this:

Sequelize is an extensively employed ORM for Node.js. It supports relational databases, such as MySQL, PostgreSQL, SQLite, and MSSQL. Sequelize boasts a comprehensive array of features for database modeling and querying. It caters to various coding styles by accommodating both Promise and Callback-based APIs. Moreover, it encompasses advanced functionalities such as transactions, migrations, and associations, making it well-suited for intricate database operations.

I made a small change to the new documentation for Sequelize! I was just scrolling through the documentation and found this mistake that could lead others to weird debugging sessions, so as soon as I found it, I submitted a PR for them! You can check out the contribution here!

The image above is a chart comparing three popular ORM tools from the npmtrends.com. ERDIA only supports TypeORM for now, but the roadmap is to support Sequelize and Prisma as well.

I tried every solution in this guide https://github.com/sequelize/sequelize/issues/6907 and many others, but I feel that Next 13 is the latest and it is not supporting other ORMs than Prisma. And I am not comfortable working with Prisma due to the absence of migrations, CLI and so much more.

I mean I am not really a pro be dev. But there is such tools as https://sequelize.org/ and it can work with different DBs, if your current DB doesn't support this you can always switch to that one which do. Switching to another language doesn't really do much.

In my usual NodeJS tech stack, which includes GraphQL, NestJS, SQL (predominantly PostgreSQL with MikroORM), I encountered these limitations. To overcome them, I've developed a new stack utilizing Rust, which still offers some ease of development:

Mikro-ORM is a TypeScript ORM that focuses on simplicity and efficiency. It supports various SQL databases and MongoDB. Mikro-ORM is known for its simplicity and developer-friendly APIs. It provides a concise syntax for defining data models and relationships, making it easy to use.

I found MikroORM [0] to be quite reasonable if you're in the TS ecosystem already. It was also easy to do custom, raw queries, and really just felt like it wasn't in the way.

It also does code generation into its own module, so good luck with hoisting in a monorepo where you want multiple independent prisma schemas. MikroORM[1] is a much better alternative to Prisma in my opinion but any ORM carries some form of baggage.
