# Data API Local Serverless Plugin

[![Master](https://github.com/marcgreenstock/data-api-suite/workflows/master/badge.svg)](https://github.com/marcgreenstock/data-api-suite/actions) [![NPM](https://img.shields.io/npm/v/data-api-local-serverless.svg)](https://www.npmjs.com/package/data-api-local-serverless)

## Summary

**Data API Local Serverless Plugin** is a plugin for the [Serverless Framework](https://serverless.com/) that starts a [Data API for Aurora Serverless](https://aws.amazon.com/blogs/aws/new-data-api-for-amazon-aurora-serverless/) emulator. Its purpose is to simplify the development of serverless applications using the Data API by making it available offline and local, similar to [serverless-dynamodb-local](https://github.com/99xt/serverless-dynamodb-local) but for PostgreSQL (MySQL coming soon).

## [Data API for Aurora Serverless Suite](https://github.com/marcgreenstock/data-api-suite#readme)

This library is part of the **[Data API for Aurora Serverless Suite](https://github.com/marcgreenstock/data-api-suite#readme)**, a [monorepo](https://en.wikipedia.org/wiki/Monorepo) that includes libraries, [Serverless Framework](https://serverless.com/) plugins and development tools to simplify and enhance the development, deployment and use of the [Data API for Aurora Serverless](https://aws.amazon.com/blogs/aws/new-data-api-for-amazon-aurora-serverless/) on Amazon Web Services.

## Installation

```sh
$ npm install data-api-local-serverless serverless-offline --save-dev
