nestjs-auth-graphql-mikroorm-starter VS TypeORM

GitHub - Jenyus-Org/nestjs-auth-graphql-mikroorm-starter: A NestJS boilerplate with authentication, GraphQL and MikroORM.

Well, the best I can offer is the NestJS starter that I go over in the third blog post I linked. I have two implementations of it, one using TypeORM and one using MikroORM. Other, more complex, projects unfortunately aren't open-source for the time-being, but they all implement the same patterns that I went over in the posts.

The good thing about NestJS at least is that MikroORM has a great integration for it. It may not be first-party but at least it's almost a drop-in replacement for TypeORM and I'm really hoping it starts doing well. I've also started to transition to it for my company and have been working in a boilerplate for this setup if you're curious in checking it out.

I see, thanks! I'm actually working on implementing that in my MikroORM NestJS boilerplate which is a copy of my TypeORM version of that. I'm mostly just a little worried about production performance and stability, but at least MikroORM uses KnexJS under the hood so I have a very familiar query builder to work with if issues arise whereas TypeORM's query builder isn't that great IMHO.

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.

We decided to use MySQL for a database. and TypeOrm for ORM. The ER diagram is provided below. For example, the task_assignments table holds information about user assignments to tasks. While in DDD, there is a pattern to design denormalized tables that reflect the structure of domain objects more directly, but this time, a more conventional table design was chosen. TypeOrm models:

How does this compare to using directly an ORM lib that supports browser like TypeORM [0] via SQL.js [1]?

* Patch a third-party library that was setting an HTTP header to `null`. NodeJS handles this case just fine, but Deno throws an error [2].

After all of that work, I finally was able to use Deno in my project. It was really cool! Unfortunately, both VS Code and IntelliJ with Deno are essentially unusable [3]. Or, at least, unacceptably slow compared to what I had with NodeJS.

TypeORM is a very convenient ORM for JS apps. We use it with NestJS and running it on NodeJS.

We are going to start using TypeORM as an ORM to help us interact with Postgres, but we also have an example of using Prisma in the future and everything that we have to adapt to switch the ORMs if necessary. At the end we are implementing neon.tech as a production database, right? 😉

TypeORM is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a high-level abstraction over relational databases, making it easy to perform CRUD (Create, Read, Update, Delete) operations.

TypeORM places its focus on TypeScript and JavaScript (ES7+) development. It offers compatibility with various database systems, including MySQL, PostgreSQL, SQLite, and MongoDB. What sets TypeORM apart is its robust integration with TypeScript. It provides a user-friendly experience with a convenient decorator-based syntax for defining entities and relationships. Additionally, TypeORM supports the repository pattern and enables eager loading, enhancing its versatility for developers.

ᴬ typeorm officially supports mssql@v9, but the support for the custom stream builder was added in mssql@v10. Since mssql is a peer dependency of typeorm, you can force override it and use the Cloud SQL Connector with typeorm. There is an open PR to add support for mssql@v10 in typeorm.
