Push with schema in separate files

I have my schemas setup something like customer.ts vendor.ts inventory.ts public.ts In my config I have schema: "./app/lib/data/db/schema/*" In public.ts I am creating tables with pgTable but in the non public ts files I am creating a schema with export const customer = pgSchema("customer") and then creating tables with export const customerTable = customer.table("customer", {fieilds here}) When I run drizzle-kit push:pg all that is created is anything in the public file and pgTable What am I missing?

Tried it with the simple example in docs too and it still doesn’t work ‘import { serial, text, pgTable, pgSchema } from "drizzle-orm/pg-core"; export const mySchema = pgSchema("my_schema") export const mySchemaUsers = mySchema.table('users', { id: serial('id').primaryKey(), name: text('name'), });’

@A_Dev I do the same thing

database/schema/index.ts

database/index.ts looks something like this:

import { schema, relations } from "./schema"

const db = drizzle(client, {
    schema: {
        ...schema,
        ...relations
    },
})

export {
    db, 
    schema,
    relations,
    ...
}

import { schema, relations } from "./schema"

const db = drizzle(client, {
    schema: {
        ...schema,
        ...relations
    },
})

export {
    db, 
    schema,
    relations,
    ...
}

tsconfig.json

{
  ...,
  "compilerOptions": {
    ...,
    "paths": {
      ...,
      "@database": [
        "./src/lib/server/database"
      ],
    }
  }

{
  ...,
  "compilerOptions": {
    ...,
    "paths": {
      ...,
      "@database": [
        "./src/lib/server/database"
      ],
    }
  }

Basic server side useage:

import { db, schema } from "@database"

const results = await db.select().from(schema.users)
// or
const results = await db.query.users.findMany()

import { db, schema } from "@database"

const results = await db.select().from(schema.users)
// or
const results = await db.query.users.findMany()

The setup docs are a mess, so it took a lot of trial and error

Yeah they are. Much appreciated I’ll give that a shot!

@Scarcer why redeclare the schemas and relations as additional objects? surely using a barrel export would achieve the same effect and have far less code on your part eg

export * from "./users"
export * from "./email"
....other schema definitions

export * from "./users"
export * from "./email"
....other schema definitions

@Scarcer im asking from a point of best practices and effeciency. I am genuinely curious regarding the thought process behind your implementation

Scarcer•12mo ago

@Darth_Fuzzy The reason is lame. Simply, linters in vs code don't track that implementation as well.

Waking up this post again! Let's say if I want to have a schema for auth, audit and public. If I try to delegate this to different files I get: ReferenceError: Cannot access 'authSchema' before initialization The error disappears if I put all the table definitions in the same file as the authSchema. How would I approach this problem in a structured way?
