Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
LINQ to DB
- Upserting complex data models from an API into EF Core entities

LiteDB: A .NET embedded NoSQL database
Before checking this out, people might want to take a look through the issues and pull requests of which there are 500+ and 50+ respectively [1]. I was really optimistic about this project and it was headed in a great direction, but it's not in a production ready state, and it seems that the main guy behind it has decided to move onto other things. It's been about a year since there was any significant activity.
I just mention this because a lot of these little issues might only become more apparent after integrating the db into your project and so it can be a bit annoying. I ended up swapping to Linq2DB [1]. It's something, more or less, similar offering an ORM/LINQ type system as well as the ability to also use direct SQL if desired. But the neat thing is that it also uses a standardized API for the LINQ query language, so you can do things like swap from SQLite to PostgreSQL in one* line of code, so long as you're not using any provider specific extensions.

Flyweight: An ORM for SQLite
I had a positive experience with Linq2db? https://github.com/linq2db/linq2db
I mention because I had something of the opposite experience with it. It not only ended up yielding the correct queries, but I saw a significant increase in performance. And the neat thing about it, beyond ORM and linq-to-sql, is a common interface amongst providers - so you can do things like swap from SQLite to Postgres with 1 line* of code, so long as you're not using provider specific extensions.

.NET 6 - ORM vs Stored Procedures - Azure Functions + SQL Databases
Temporary tables are covered by linq2db. But better to show Stored Proc maybe your final query just needs several CTE which also supported by linq2db.
-
Expression trees for LINQ
My learning path was supporting linq2db, not short way. StackOverflow was original source to find something like, how to do if operator in Expression Tree, how to throw exception in Expression Tree, how to build dynamic filter, ect.

Dapper is it worth using now with the improvements in EF in dotnet 6?
Checkout linq2db No need for Dapper or EF with this library. I wouldn't want to miss it.
- What is the best PostgreSQL ORM tool for use in a .NET Framework 4.7 application?
-
SchemaTypist: Entity generator for Dapper and SqlKata
Why not linq2db? Faster than Dapper and has LINQ support.
-
EF Core is good for most things.
Probably you can understand why linq2db was born 15 years ago
-
EF vs Dapper - a false dilemma
As others have mentioned, I think linq2db comes closest to this.

NodeJS Security Best Practices
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.

[DDD] Tactical Design Patterns Part 3: Presentation/Infrastructure Layer
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:

SQLSync – Stop Building Databases
How does this compare to using directly an ORM lib that supports browser like TypeORM [0] via SQL.js [1]?
-
Deno Cron
* 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 - remove children with orphanedRowAction
TypeORM is a very convenient ORM for JS apps. We use it with NestJS and running it on NodeJS.

Authentication part 3 using NestJS and Postgres database neon.tech
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? 😉

From Good to Great: Scaling Applications with TypeORM Optimization
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.

Top 6 ORMs for Modern Node.js App Development
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.

Deep Dive into Google Cloud SQL Connector for Node.js
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.

Leverage the power of PostgreSQL for validating data
By the way, what is ORM (and TypeORM)? The scope of this post will be increased if I introduce those. I recommend checking out What is an ORM by Ihechikara Vincent Abba and TypeORM’s official documentation.
What are some alternatives?
