knex-types VS pgtyped

GraphQL.js + Knex.js + knex-types (TypeScript generator for Knex)

And in order to have auto-complete and type checking, you can combine it with knex-types.

I generate TypeScript enums and types from the actual database schema using knex-types as part of the yarn db:reset script that used during local development (after making changes to the db schema migration files). See example project.

I tried to take advantage of TypeORM in a couple of projects, but then reverted back to knex + knex-types — just a PostgreSQL client with query builder works great, IMO, especially for GraphQL API development.

Nope. Just plain GraphQL.js + Knex.js (example), often typed manually since it's not where most of the time spend on when building an API server (though it can be automated via a scaffolding script if there are too many db tables). Generating TypeScript definitions off the actual db schema using knex-types (example).

Luckily, there is a solution! Assuming you have a database table that looks like this (Knex migration):

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 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/.

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!

Cool. How does this compare to SafeQL, PgTyped, and Postgres language server ?

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.

There's pgtyped, which I believe does almost the same as sqlc

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

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.

I would highly recommend trying out pgTyped if you want typesafe queries with postgres. It's fantastic!
