Drizzleでcreated_atとupdated_atを設定する

import { timestamp } from "drizzle-orm/pg-core";

export const timestamps = {
  createdAt: timestamp("created_at", { mode: "date", precision: 3, withTimezone: true })
    .defaultNow(),
  updatedAt: timestamp("updated_at", { mode: "date", precision: 3, withTimezone: true })
    .defaultNow()
    .$onUpdateFn(() => new Date())
};

export const projects = pgTable("projects", {
  id: serial("id").primaryKey(),
  slug: text("slug").notNull().unique(),
  displayName: text("display_name").notNull(),
  ...timestamps
});
