# Create User

> Create a new user in the system with email and password

This endpoint creates a new user account in the PostgreSQL database using Prisma ORM. The user data is stored with the provided email and password.

## Endpoint

```
POST /usuarios
```

## Request Body

<ParamField body="email" type="string" required>
  The user's email address. Must be unique in the database.
</ParamField>

<ParamField body="password" type="string" required>
  The user's password. This will be stored as provided (note: password hashing should be implemented for security).
</ParamField>

## Response

<ResponseField name="id" type="integer">
  The unique identifier assigned to the newly created user
</ResponseField>

<ResponseField name="email" type="string">
  The email address of the created user
</ResponseField>

<ResponseField name="password" type="string">
  The password as stored in the database
</ResponseField>

## Status Codes

* **201 Created** - User successfully created
* **500 Internal Server Error** - Database error or validation failure

## Example Request

```bash theme={null}
curl -X POST http://localhost:3000/usuarios \
  -H "Content-Type: application/json" \
  -d '{
    "email": "user@example.com",
    "password": "securePassword123"
  }'
```

## Example Response

### Success (201)

```json theme={null}
{
  "id": 1,
  "email": "user@example.com",
  "password": "securePassword123"
}
```

### Error (500)

```json theme={null}
{
  "error": "Error al insertar en Postgres"
}
```

## Error Handling

Common errors include:

* **Duplicate email**: If the email already exists in the database
* **Missing required fields**: If email or password is not provided
* **Database connection issues**: If the PostgreSQL database is unavailable

## Implementation Details

The endpoint implementation (from `/backend/index.js:24-36`):

```javascript theme={null}
app.post('/usuarios', async (req, res) => {
  try {
    const nuevoUsuario = await prisma.user.create({
      data: {
        email: req.body.email,
        password: req.body.password
      }
    });
    res.status(201).json(nuevoUsuario);
  } catch (error) {
    console.log("DETALLE DEL ERROR:", error);
    res.status(500).json({ error: "Error al insertar en Postgres" });
  }
});
```

## Security Considerations

<Warning>
  The current implementation stores passwords in plain text. For production use, implement password hashing using bcryptjs (already imported in the project).
