+# REST API Example with Elysia & Prisma
+
+This example shows how to implement a **simple Todo REST API with TypeScript** using [Elysia](https://elysiajs.com/) and [Prisma Client](https://www.prisma.io/docs/concepts/components/prisma-client). It connects to a Postgres database via the [`@prisma/adapter-pg`](https://www.prisma.io/docs/orm/overview/databases/postgresql/pg-driver-adapter) driver adapter.
+
+This example uses [Prismabox](https://github.com/m1212e/prismabox) to automatically generate Elysia validation models from the Prisma schema, ensuring type safety and eliminating the need to manually define validation schemas.
+
+## Project structure
+
+- `src/index.ts` – defines the Elysia server and the REST routes for todos.
+- `src/lib/prisma.ts` – creates a Prisma Client using `@prisma/adapter-pg`.
+- `prisma/schema.prisma` – Prisma schema with the `Todo` model.
+- `prisma/seed.ts` – seeds the database with sample todos.
+
+## Getting started
+
+### 1. Download the example and install dependencies
+
+```bash
+npx try-prisma@latest --template orm/elysia --name elysia
+cd elysia
+bun install
+```
+
+> Alternatively clone this repo and run `bun install` inside `prisma-examples/orm/elysia`.
+
+### 2. Configure `DATABASE_URL`
+
+Create a Postgres database (Prisma Postgres, Supabase, Railway, Docker, etc.) and copy the direct connection string:
+
+```
+postgresql://USER:PASSWORD@HOST:PORT/DATABASE?sslmode=require
+```
+
+Create a `.env` file in the project root and add the URL:
+
+```bash
+touch .env
+
+# .env
+DATABASE_URL="postgresql://USER:PASSWORD@HOST:5432/DATABASE?sslmode=require"
+```
+
+### 3. Generate Prisma Client & Prismabox models, migrate & seed the database
+
+```bash
+bunx prisma generate
+bunx prisma migrate dev --name init
+bunx prisma db seed
+```
+
+This generates:
+- **Prisma Client** - for database operations
+- **Prismabox models** - Elysia validation schemas (in `src/generated/prismabox/`)
+- Creates the tables defined in [`prisma/schema.prisma`](./prisma/schema.prisma)
+- Runs [`prisma/seed.ts`](./prisma/seed.ts) to insert demo data
+
+### 4. Start the REST API server
+
+```bash
+bun run dev
+```
+
+The server listens on `http://localhost:3000`.
+
+## API Endpoints
+
+- `GET /todos` – get all todos
+- `GET /todos/:id` – get a single todo by ID
+- `POST /todos` – create a new todo
+- `PUT /todos/:id` – update a todo
+- `PATCH /todos/:id/toggle` – toggle todo completion status
+- `DELETE /todos/:id` – delete a todo
+
+## Example API requests
+
+### Get all todos
+
+```bash
+curl http://localhost:3000/todos
+```
+
+### Create a todo
+
+```bash
+curl -X POST http://localhost:3000/todos \
+  -H "Content-Type: application/json" \
+  -d '{"title": "Buy groceries"}'
+```
+
+### Update a todo
+
+```bash
+curl -X PUT http://localhost:3000/todos/1 \
+  -H "Content-Type: application/json" \
+  -d '{"title": "Buy groceries and cook dinner", "completed": true}'
+```
+
+### Toggle todo completion
+
+```bash
+curl -X PATCH http://localhost:3000/todos/1/toggle
+```
+
+### Delete a todo
+
+```bash
+curl -X DELETE http://localhost:3000/todos/1
+```
+
+## Features
+
+- **Type-safe API**: Elysia's built-in schema validation with `Elysia.t` ensures type safety at both runtime and compile time.
+- **Prismabox Integration**: Automatically generates Elysia validation models from Prisma schema, eliminating manual schema definitions.
+- **Prisma ORM**: Full type safety with Prisma Client and automatic type inference.
+- **PostgreSQL**: Uses `@prisma/adapter-pg` for direct database connections.
+- **Bun runtime**: Optimized for Bun's fast JavaScript runtime.
