> ### ElysiaJS + Drizzle ORM codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the [RealWorld](https://github.com/gothinkster/realworld) spec and API.

This codebase was created to demonstrate a fully fledged backend application built with **[ElysiaJS](https://elysiajs.com/)** and **[Drizzle ORM](https://orm.drizzle.team/)** including CRUD operations, authentication, routing, pagination, and more.

We've gone to great lengths to adhere to the **ElysiaJS** and **Drizzle ORM** community styleguides & best practices.

For more information on how this works with other frontends/backends, head over to the [RealWorld](https://github.com/gothinkster/realworld) repo.

# How it works

## Architecture

This project follows the [Bedstack](https://bedstack.js.org/) architecture - a modular, layered approach to building TypeScript backends:

- **Modular structure** - Each domain (users, articles, comments, etc.) is a self-contained module with its own controller, service, repository, and DTOs
- **Layered design** - Clear separation between Controller (HTTP handling) → Service (business logic) → Repository (data access)
- **Type-safe data flow** - DTOs define request/response shapes, mappers transform between layers, schemas define database tables

```
src/
├── users/          # User module
│   ├── users.controller.ts
│   ├── users.service.ts
│   ├── users.repository.ts
│   ├── users.schema.ts
│   ├── dto/
│   └── mappers/
├── articles/       # Article module (same structure)
├── shared/         # Shared utilities and error handling
└── app.module.ts   # Root module composing all features
```

## Technologies

- **[ElysiaJS](https://elysiajs.com/)** - Web framework for HTTP
- **[Drizzle ORM](https://orm.drizzle.team/)** - TypeScript ORM for PostgreSQL
- **[ArkType](https://arktype.io/)** - Runtime validation
- **[Scalar](https://scalar.com/)** - API documentation
- **[Bun](https://bun.sh/)** - JavaScript runtime and package manager
- **[Biome](https://biomejs.dev/)** - Linting and formatting

# Getting started

1. **Install dependencies**

```sh
    bun i
    ```

2. **Create a `.env` file**

```sh
   cp .env.example .env
   ```

Use the provided example values or replace them with your own.

3. **Ensure Docker daemon is running and start the database service**

```sh
   bun db:start
   ```

4. **Migrate the schema to the database**

```sh
   bun db:migrate
   ```

5. **Run the development server**

```sh
   bun dev
   ```

6. **Run the API tests**

```sh
   bun run test # not `bun test`!
   ```

7. **(Optional) Start the [database studio](https://orm.drizzle.team/drizzle-studio/overview)**
   ```bash
   bun db:studio
   ```

# Deploy to production

> [!TIP]
> See more info in ElysiaJS's [Deploy to production](https://elysiajs.com/patterns/deploy) pattern.

1. **Build the app**

```sh
   bun run build # not `bun build`!
   ```

2. **Run the server**

```sh
   bun preview
   ```
