# migration:create

> Generate a new migration file.

Generate a new migration file with its test file inside a module. The migration is named automatically from a timestamp version, the `migrations.ts` export file is regenerated, and `bin/migration/up.ts` is created for the module if it does not already exist.

## Usage

```bash theme={null}
ooneex migration:create [options]
```

## Examples

```bash theme={null}
ooneex migration:create
```

```bash theme={null}
ooneex migration:create --module=blog
```

## Options

| Option     | Description                         | Default  |
| ---------- | ----------------------------------- | -------- |
| `--module` | Module the migration is created in. | `shared` |
