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.

any recommendations for a good query builder library with good support?
I recently started using drizzle orm and I am now looking for something similar in python, my goal is to be as close to sql syntax as possible without just passing dml commands as strings, type safety would be cool as well, I saw this one pypika but it ha a lot of open issues and no commits for a year, is there anything similar but more stable?

Ask HN: Is SQLAlchemy the industry standard Python ORM in 2023?
Yes it is. I haven't seen many Python projects using Prisma and
Note that there are several types of technologies that can help connect an application to an SQL database:
- SQL builders: the best known project seems to be Pypika by Kayak (https://github.com/kayak/pypika) but it seems to be dead of sleeping.

Write an SQL query builder in 150 lines of Python
https://github.com/kayak/pypika
Have used in multiple projects and have found it's the right balance between ORMs and writing raw SQL. It's also easily extensible and takes care of the many edge cases and nuances of rolling your own SQL generator.

Migrating to SQLAlchemy 2.0
There is a middle-ground between writing SQL statement strings in your code, and a full-blown ORM: query builders. At least in my experience with small to medium projects, these have far fewer footguns while keeping the code composable and readable. Here's one for Python: https://github.com/kayak/pypika

Sneakiest development trap: making easy easier...
And sometimes invest instead in learning a technology rather than hide it: for example slonik encourages you to write normal SQL queries by making SQL templating easier and safer. In turn, your IDE would be able to understand those queries and give you support based on the database schemas you actually have.

Drizzle is just as unready for prime-time as Prisma, what else is there?
I'd push you to consider using postgres, slonik or similar for database queries. With these libraries, you just write SQL, but they perform input sanitization for you. So you can safely write:
- Slonik: PostgreSQL client for Node.js with runtime validation
-
PostgresJs: The Fastest full featured PostgreSQL client for Node.js and Deno
You can already use postgres with Slonik.

It is not going to be the default because it is way slower.

Test node_version:18 test_only:postgres-integration is taking 3 minutes.
Test node_version:18 test_only:pg-integration is taking 38 seconds.

Integrating Slonik with Express.js
For those uninitiated, Slonik is a battle-tested SQL query building and execution library for Node.js. Its primary goal is to allow you to write and compose SQL queries in a safe and convenient way. Now, let's see how it pairs with Express.js.
-
Which Postgres client are you using?
I am the maintainer of Slonik and I am trying to understand what portion of this sub-users are using Slonik vs other libraries, and if they are using anything else – what are their reasons for it.

JEP Draft: String Templates (Final)
It's nice that they implemented string templates essentially exactly the same way Javascript template literals and tag functions work. They even give an example of using it to create a prepared statement (e.g. DB."SELECT * FROM foo WHERE bar = \{inputParam}") which is exactly what many NodeJS libraries due, e.g. Slonik https://github.com/gajus/slonik, like sql`SELECT * FROM foo WHERE bar = ${inputParam}`;

We use TypeScript not based on preference, but because we want to make money
I've found libraries like Zod useful when interacting with external data sources like a database. Slonik[1] uses Zod to define the types expected from a SQL query and then performs runtime validation on the data to ensure that the query is yielding the expected type.
I don't think it's necessary to use Zod/runtime validation everywhere, but it's a nice tool to have on hand.

Is ORM still an anti-pattern?

The Epic Stack by Kent C. Dodds
Have you tried Slonik (https://github.com/gajus/slonik)? It won't generate types from queries automatically, but it encourages writing SQL vs. a query builder and allows type annotations of queries with Zod. Query results are validated at runtime to ensure the queries are typed correctly.
