# Mock Data

Generate mock user records as JSON for testing and development.

## Commands

```bash
devv mock                        # 5 records
devv mock --count 20             # 20 records
```

## Examples

```bash
# Generate test data
devv mock --count 10

# Save seed data to file
devv mock --count 100 > seed-data.json

# Generate and format
devv mock --count 3 | devv json format
```

## Output

```bash
$ devv mock --count 2
[
  {
    "id": 1,
    "name": "User 1",
    "email": "user1@example.com",
    "createdAt": "2026-06-15T08:23:41.000Z"
  },
  {
    "id": 2,
    "name": "User 2",
    "email": "user2@example.com",
    "createdAt": "2026-07-01T14:12:09.000Z"
  }
