How to implement interface for table?

Say I have an interface of User

interface User {
  id: string,
  name: string,
  age: number
}

interface User {
  id: string,
  name: string,
  age: number
}

and this is how I declare my schema

export const user = pgTable("user", {
  id: serial("id"),
  name: text("name"),
  age: integer("age"
});

export const user = pgTable("user", {
  id: serial("id"),
  name: text("name"),
  age: integer("age"
});

How do I make sure that the user table implement the User interface that I have declared?

Why do it the other way? You can first declare schema and be it your interface with

type User = InferModel<typeof user>

type User = InferModel<typeof user>

This, I’m working in a monorepo where I have a module for Web, one for API and one for shared interface. The workflow is I first create an interface in the shared interface module then use it in both web and api modules. This way I can make sure the api returns the correct type for the web.

@nqhtrung I'm not sure if this is what you are looking for, but the types in here might be helpful for you: https://github.com/digidem/mapeo-core-next/blob/981070acfd22ca68d4537f666749bccc5ef033dc/lib/schema/schema-to-drizzle.js (they might not be completely correct - this is an in-progress PR)
