# prisma-database-rewinder

[![npm version](https://badge.fury.io/js/prisma-database-rewinder.svg)](https://badge.fury.io/js/prisma-database-rewinder)

`prisma-database-rewinder` is a port of [database-rewinder](https://github.com/amatsuda/database_rewinder) for [Prisma](https://github.com/prisma/prisma).  

This library is designed to **extremely fast** clean up test database records in Integration tests using a database.  

It's currently intended for use with Jest and PostgreSQL.  

## Installation

```

npm install prisma-database-rewinder

or

yarn add prisma-database-rewinder

or

pnpm add prisma-database-rewinder

```

## Usage

At the beginning of your Jest test file, include the following setup:

```typescript

// prepare prisma client for test db

const prismaTestClient = new PrismaClient();

const rewinder = new PrismaDatabaseRewinder(prismaTestClient);

beforeAll(async () => {

  await rewinder.beforeAll();

});

afterEach(async () => {

  await rewinder.afterEach();

});

```

This setup ensures that your test database is cleaned up before all tests run and after each test completes, keeping your database in a consistent state and ready for the next test.
