Automatically apply migrations on serverless deploy

I've got a basic Todo app using Turso DB and Nuxt: https://github.com/Amar-Gill/nuxt-todo I'm wondering if there is a way to automatically apply migrations when I deploy to Vercel? The build command is npm run build. Right now, I open a shell into my Turso DB and paste the migration scripts. I might have to wait for a migration runner in drizzle-kit to ship: https://orm.drizzle.team/kit-docs/faq#how-do-i-apply-migrations-generated-by-drizzle-kit

part of the challenge of using the migrate function is that the _journal.json file is not preserved in a nuxt build output

here's an example using nitro plugin system: https://github.com/Atinux/nuxt-todos-edge/blob/main/server/plugins/migrations.ts but again only for dev -- on prod the _journal.json file is not available

can also use nuxt build time hooks:

import { createDb } from "./server/utils/drizzle/create-db";
import { migrate } from "drizzle-orm/libsql/migrator";

// https://nuxt.com/docs/api/configuration/nuxt-config
export default defineNuxtConfig({
  devtools: { enabled: true },
  runtimeConfig: {
    tursoDbUrl: "file:./server/sqlite.db",
    tursoDbToken: "",
  },
  hooks: {
    ready(nuxt) {
      const runtimeConfig = nuxt.options.runtimeConfig;

      const db = createDb(runtimeConfig);

      console.log("Migrating database...");
      migrate(db, { migrationsFolder: "./drizzle" })
        .then(() => console.log("Database migrated."))
        .catch(console.error);
    },
  },
});

import { createDb } from "./server/utils/drizzle/create-db";
import { migrate } from "drizzle-orm/libsql/migrator";

// https://nuxt.com/docs/api/configuration/nuxt-config
export default defineNuxtConfig({
  devtools: { enabled: true },
  runtimeConfig: {
    tursoDbUrl: "file:./server/sqlite.db",
    tursoDbToken: "",
  },
  hooks: {
    ready(nuxt) {
      const runtimeConfig = nuxt.options.runtimeConfig;

      const db = createDb(runtimeConfig);

      console.log("Migrating database...");
      migrate(db, { migrationsFolder: "./drizzle" })
        .then(() => console.log("Database migrated."))
        .catch(console.error);
    },
  },
});
