## Usage

```terminal
  $ npx @prisma/codemods <transform> <path> <...options>
```

- `<transform>` - See [Transforms](#transforms) for available choices
- `<path>` - The directory of your app. i.e ./my-awesome-project

## Options

- `(-f)orce` - Bypass Git safety checks and forcibly run codemods
- `(-s)chemaPath` - Specify a path to your ./prisma/schema.prisma
- `(-d)ry` - Dry run (no changes are made to files)
- `(-p)rint` - Print transformed files to your terminal
- `--instanceNames=myClient` - Useful when importing an already instantiated client (i.e import myClient from './myClient')

## Transforms

| `<transform>` | Description                                                 | Example                                         |

| `to$`         | to\$: Converts deprecated `prisma.x` methods to `prisma.$x` | `npx @prisma/codemods to$ ./my-project`         |
| `update-2.12` | Includes `namespace`/`findUnique`/`to$`                     | `npx @prisma/codemods update-2.12 ./my-project` |
