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.

Ask HN: Does Anyone Like GraphQL?
The main (and only) criticism I’ve ever heard about graphql in the companies I worked for was that it is very js-oriented all the best libs/frameworks for it are for react frontend / node server mostly.
Backend scala / php devs looked at it with distaste in their eyes, coming up with various reasons why its not a good idea.
And to be fair with tools like openapi / grpc a lot of the benefits of graphql can be replicated.
Even if they are clumsy and fragmented compared to it in my eyes, they still work well enough and keep devs in all camps happy enough, and compromise as they say is “when everyone is equally unhappy”.
Now placed in situations like this I am usually forced to reimplement graphql tooling with the chosen api tech (for example https://github.com/ovotech/laminar) and if me as a single dev could do it, then I’d wager if there was stronger tech leadership, all the other tech tribes could just smooth the edges that they didn’t like for using graphql in their respective languages … but sadly that has not been my experience.

Ask HN: Do you use JSON Schema? Help us shape its future stability guarantees
I use it extensively in prod. Well the superset that is OpenApi. It enables contract first development where any change to the api is done in the schema fist, and then implemented by the clients/server.
Since we have tooling[0] that validates requests and responses at runtime, the clients can be absolutely sure of what they receive (we through 500 if the server attempts to respond with an undocumented respond) And the server is also sure about the shape of the requests. This allows us to validate everything at compile time too, generating typescript types for both client and server.
And since we have similar tooling regarding our data stores (typescript types for sql queries) most of the time if there is a bug, the code would simply not compile - pretty nifty!

Bad TypeScript Habits to Break This Year
If the api has some contract with it OpenApi / Swagger / etc, its surprisingly easy to write a parser that would convert those to typescript types. TS has an awesome use as a library itself where you can write the ast with, and then tell it to convert it to code.
We use it to great effect ourselves, by generating types for axios.
https://github.com/ovotech/laminar/tree/main/packages/lamina...
Now granted, you’re now trusting the api writers with their contract, but if its another team in the org we’ve found it to be warranted.

Type-Safe Printf() in TypeScript
There is an implementation of SQL that operates on a table shaped type, entirely at type level. For your amusement: https://github.com/codemix/ts-sql
There are a bunch of more practical takes that codegen types from your database and generate types for your queries, eg: https://github.com/adelsz/pgtyped
To me the second approach seems much more pragmatic because you don’t need to run a SQL parser in a fairly potato interpreter on every build

ORMs are nice but they are the wrong abstraction
ORMs suck, but raw SQL embedded in your code sucks too.
This might be good time to plug my TypeScript non-ORM: https://jawj.github.io/zapatos/.
I should say I also like what I've seen of https://kysely.dev/ and https://pgtyped.dev/.

An effective way to build a heavy CRUD Rest API?
Thank you for suggestions they helped me finding what I was looking for. I will either pick kysely or https://pgtyped.dev/, but first I will do some tests. Thanks!

compile-time SQL validations and type generation in TypeScript & Node
Cool. How does this compare to SafeQL, PgTyped, and Postgres language server ?

Petrol: embedding a type-safe SQL API in OCaml using GADTs
I would instead rely on code generation like https://github.com/adelsz/pgtyped, because the embedded type-safe SQL will never fully cover all the features of vanilla SQL, for example Common Table Expression (CTE), window functions etc.

Kysely: TypeScript SQL Query Builder
For Postgres there is https://github.com/adelsz/pgtyped, sounds pretty much like what you describe?

Is postgresql-typed a good starting library for a production application?
Avoiding the cost of learning EDSL that many Haskell DB libraries provide, I found out that only postgresql-typed and postgresql-simple allow to write only raw SQL queries easily. As I extensively use pgtyped for production Node.js application, I am thinking about using postgresql-typed. While I could find many resources for postgresql-simple, the same cannot be said try for postgresql-typed.
