ADVICE WANTED - Typescript PostgreSQL without ORM
I have so far found: - kanel https://github.com/kristiandupont/kanel - and pg-to-ts https://github.com/danvk/pg-to-ts

Postgres to TypeScript Interfaces and Enums
There are many forks of schemats out there that add various features. Here’s mine: https://github.com/danvk/pg-to-ts
It copies Postgres comments over to JSDoc/TSDoc comments, emits some data about foreign key relationships and supports TS types for json/jsonb columns via @type comments. Feel free to copy any of those feature if you think they’re good ideas :)

I made a Twitter clone using Deno and Fresh
Did you check https://github.com/koskimas/kysely ? It was great when I used it. It has great TS support.
- Full-Stack TypeScript with tRPC and React

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.
