$inferSelect and $inferInsert doesn't return table types

Hey There, Im Using Koa.js having issues with inserting as the types arent correctly referenced from the table. tsconfig.json:

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "commonjs",
    "lib": ["ESNext"],
    "outDir": "dist",
    "rootDir": "src",
    "noImplicitAny": false,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "esModuleInterop": true,
    "skipLibCheck": false,
    "forceConsistentCasingInFileNames": true,
    "moduleResolution": "node",
    "allowSyntheticDefaultImports": true,
    "strict": true
  },
  "include": ["src/**/*.ts", ".drizzle.config.ts"],
  "exclude": ["node_modules", "dist"]
}

drizzle.config.ts:

import { defineConfig } from "drizzle-kit";

export default defineConfig({
  dialect: "postgresql",
  schema: "./src/database/schema",
  out: "./drizzle",
  dbCredentials: {
    url: process.env.DATABASE_URL as unknown as string,
  },
});

Drizzle instantiation:


import postgres from "postgres";
import { PostgresJsDatabase, drizzle } from "drizzle-orm/postgres-js";
import dotenv from "dotenv";

dotenv.config();

import * as schema from "./schema";

declare global {
  var database: PostgresJsDatabase<typeof schema> | undefined;
}

let database: PostgresJsDatabase<typeof schema>;

const DATABASE_URL = process.env.DATABASE_URL as unknown as string;

if (process.env.NODE_ENV === "production") {
  database = drizzle(postgres(DATABASE_URL), { schema });
} else {
  if (!global.database) {
    global.database = drizzle(postgres(DATABASE_URL), {
      schema,
      logger: true,
    });
  }

  database = global.database;
}

export default database;

Here is my table definition:


export const agencies = pgTable("agencies", {
  id: serial("id"),
  //   id: varchar("id", { length: 32 })
  //     .$defaultFn(() => generateId("user"))
  //     .primaryKey(),
  name: text("name").notNull(),
  createdAt: timestamp("created_at").defaultNow().notNull(),
  updatedAt: timestamp("updated_at").default(sql

current_timestamp

),
  deletedAt: timestamp("deleted_at"),
});

export type Agency =  typeof agencies.$inferSelect;
export type NewAgency = typeof agencies.$inferInsert;

Agency type outputs to:

type Agency = any

NewAgency type outputs to:


type NewAgency = {
    name: any;
    id: any;
    createdAt: any;
    updatedAt: any;
    deletedAt: any;
}

here is the code in my persistency layer:


export async function createNewAgency(values: NewAgency) {
  console.log(values);
  try {
    return await database.insert(agencies).values({
      name: values.name,
    });
  } catch (error) {
    console.log(error);
  }
}

Fixed: Two things to check for Make sure your typescript version is updated to latestt if possible also, if there is a silent type error within the schema definition then it will not give the correct type the culprit:

  parentId: varchar("parent_id", { length: 30 }).references(
    () => agencies.id,
    {
      onDelete: "cascade",
    }
  ),

changed to:

  parentId: varchar("parent_id", { length: 30 }).references(
    (): any => agencies.id,
    {
      onDelete: "cascade",
    }
  ),
