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.

Show HN: Sqlbind a Python library to compose raw SQL
I had my own take on this concept[1], though with considerably less language magic involved. I imagine there's a lot of these kind of things running around. My criteria were:
a) let me write actual SQL, not a python DSL that generates SQL
b) be placeholder-safe
c) be composable

Write an SQL query builder in 150 lines of Python
This is my middle-ground solution for Python: https://github.com/bdowning/sql-athame
Still fundamentally manipulating SQL text (which is a feature as I don't want to learn a full DSL), but it handles wrangling embedded placeholders while you're composing stuff and some other common compositional tasks. It's worked well for me anyway but I'm under no illusions it'd be right for everyone.
Not an original concept regardless; my original version of this was in Node: https://github.com/bdowning/sql-assassin, but a few years after I wrote that (and mostly didn't use it) I found https://github.com/gajus/slonik which was very similar and much more fleshed-out; I rolled _some_ of its concepts and patterns into sql-athame.

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.
https://github.com/gajus/slonik/actions/runs/6616647651
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.
What are some alternatives?
PyPika - PyPika is a python SQL query builder that exposes the full richness of the SQL language using a syntax that reflects the resulting query. PyPika excels at all sorts of SQL queries but is especially useful for data analysis.
Knex - A query builder for PostgreSQL, MySQL, CockroachDB, SQL Server, SQLite3 and Oracle, designed to be flexible, portable, and fun to use.
pgcli - Postgres CLI with autocompletion and syntax highlighting
TypeORM - ORM for TypeScript and JavaScript. Supports MySQL, PostgreSQL, MariaDB, SQLite, MS SQL Server, Oracle, SAP Hana, WebSQL databases. Works in NodeJS, Browser, Ionic, Cordova and Electron platforms.
