Use MikroORM with SvelteKit and Postgres

Create the database

npx ezhst db create main
npx ezhst db info --json
npx ezhst env set DATABASE_URL="postgresql://..."

The connection string uses a public host with TLS, so it works from your laptop too. Put it in your local .env for development.

Install MikroORM

npm i @mikro-orm/core @mikro-orm/postgresql

Create the client

import { MikroORM } from "@mikro-orm/postgresql";

const orm = await MikroORM.init({
  clientUrl: process.env.DATABASE_URL,
  entities: [],
});

export const db = orm.em.fork();

Register your entities in the entities array and fork the entity manager for each request in real handlers.

Anything under $lib/server is blocked from browser code, which keeps database credentials safe.

Query it from a route

import { db } from "$lib/server/db";
import { error, json } from "@sveltejs/kit";
export const GET = async ({ request }) => {
  const rows = await db.getConnection().execute("select id, email from users limit 20");
  return json(rows);
};

Run migrations

Run migrations from your machine, with DATABASE_URL set to the EasyHost connection string.

npx mikro-orm migration:up

Commit the migration files so every environment applies the same changes.

Deploy

npx ezhst deploy

Each database allows 20 concurrent connections, and SvelteKit shares them across requests. See the SvelteKit hub for every SvelteKit guide, or free SvelteKit hosting for what is included. See also the Postgres product page.

Frequently asked questions

Is Postgres free for my SvelteKit app?

Yes. Each EasyHost project can have one Postgres 16 database with no expiry date.

Can I use MikroORM locally against the same database?

Yes. The connection string works from outside EasyHost. A separate development database is safer once you have real data.
