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.

Type-safe S3 Select queries with Kysely
That’s where Kysely comes to the rescue: Kysely is a type-safe and devX-friendly typescript SQL query builder. It was designed to work with PostgreSQL and MySQL, but it exposes a few classes that can let us write queries without being connected to an actual relational database.
- Vue and trpc?

Announcing a new TypeScript ORM
prisma (mentioned in the article), zapatos, pgtyped and kysely are the most popular currently I think.
switch between a limited interface and a query builder (MikroORM, TypeORM). This feels like using two different libraries, switching between two different sets of limitations. Kysely is a nice query builder with good TS support, but MikroORM is using Knex instead so you're losing TS, and TypeORM has a custom query builder, less user-friendly than Knex.

Which ORM do you prefer with nodejs/Typescript project and why ?
I'd love to see Kysely as an option.

You might not need an ORM
Kysely[1] and zapatos[2] are excellent solutions for type-safe typescript query builders. It’s hard to go back to the days of spending 20-30% of your time in the object mapping layer.

Simple CQRS in NodeJS with Typescript
Querying the database (PostgreSQL) should not be ground breaking. Personally I like to have full type-safety so we can easily catch bugs during the development time without introducing any tests that are just testing the data type from our datastore to match the data type our API expects. I like to go database schema first, which means that we generate types from the database schema and work with those. Any change to the schema of the database is made with SQL migrations and after that, the typescript types are regenerated. Another approach is to use a code-first tool like TypeORM or Prisma. However in my experience such tools often produce not efficient SQL queries and are less easy to extend. In my projects I use library kysely (https://github.com/koskimas/kysely) with kysely-codegen (https://github.com/RobinBlomberg/kysely-codegen) to have a full type-safe SQL builder.

GraphQL and data security
I think you can't implement every security policy for every type you can request in every resolver. It requires a lot of code duplication and increase complexity. It's simply not maintainable. I ended up thinking that security policies should be applied by the layer that is in charge to load the graph, but this is just my opinion. I discussed all this things in a Medium article (https://blog.devgenius.io/how-to-secure-your-graphql-api-part-1-eb41f66ec07e) where I also proposed a solution based on a library that me and my team built to simplify the data access in a GraphQL context (it's name is Typetta and you can find more details here https://twinlogix.github.io/typetta/).

MongoDB access library in NodeJS?
I used Mongoose in the past, but I found it rough in terms of typing, that is important in a TS context. I also tried the official driver but, you know, it's only a driver. I (and my team) ended up building something new, a sort of a type-safe open-source ORM we named Typetta (https://twinlogix.github.io/typetta/). We are using it in some production projects, with a very good feedback, but my questions is still there: how do others face the problem of managing a data layer on top of MongoDB?
