SST + Drizzle ORM example project

Current example was inspired by and created from twitch stream -> https://www.twitch.tv/videos/1704293186

In this stream @thdr tried to use Prisma + Kysely to setup automatic database migrations using sst

We have prepared simple MVP example of how to achieve both migrations and ORM functionality using just Drizzle ORM

Note: Current example just showing a possibility to use drizzle orm in serverless environment using AWS Lambda/Custom Resources/etc. In next versions of those examples we can setup Custom resources, by examples how SST Team already did here

Initial setup

We used create-sst bootstrap script

npx create-sst

Add drizzle dependencies to your project using pnpm

cd packages/core
pnpm i drizzle-orm@latest
pnpm i drizzle-kit -D

Project structure

In this repo you may found same project structure as create-sst script will generate. Just few things were added:

packages/core/sql/index.ts

Current file contain drizzle AwsDataApi connection setup + drizzle migrations setup. You can check more about drizzle-orm and drizzle-kit usage

import { RDSDataClient } from "@aws-sdk/client-rds-data";
import { drizzle } from "drizzle-orm/aws-data-api/pg";
import { migrate as mig } from "drizzle-orm/postgres-js/migrator";
import { RDS } from "sst/node/rds";

const rdsClient = new RDSDataClient({});
export const db = drizzle(rdsClient, {
  database: RDS.rds.defaultDatabaseName,
  secretArn: RDS.rds.secretArn,
  resourceArn: RDS.rds.clusterArn,
});

export const migrate = async (path: string) => {
  return mig(db, { migrationsFolder: path });
};

packages/core/sql/schema.ts

Current file contains basic table schema definition, that can be used in further queries

import { integer, pgTable, text } from "drizzle-orm/pg-core";

export const users = pgTable("users", {
  id: integer("id").primaryKey(),
  name: text("name"),
});

We have added 2 Lambda Functions
- lambda.ts -> check, that query to newly created database was invoked without errors
- migrator.ts -> lambda, that currently invoked using API, to simulate migration process from lambda code

How to run this example

Install dependencies

pnpm install

Run the migration script in core package

cd packages/core
pnpm run migrate

Run sst deploy or sst dev from the root of the project

pnpm run deploy

pnpm run dev

From outputs use ApiGateway base url to invoke lambda functions. You can also run these endpoints from the SST console.
- /migrate - to simulate migration process
- / - to check if query is working as expected

Add new migrations

Core package has npm script migrate. By running this script drizzle-kit will generate new sql file in output folder, that was chosen in cli params
