## README

# AWS Amplify Data Schema Builder

This repository contains the implementation for the Amplify Data Schema Builder package `@aws-amplify/data-schema`, the Amplify Data Client `generateClient()`, as well as supporting utilities, automated tests, and performance benchmarks.

These packages are dependencies of `@aws-amplify/backend` and `aws-amplify` (Amplify JS). _They are not intended to be installed and used directly._

## Quickstart

To get started with AWS Amplify, visit [AWS Amplify Quickstart](https://docs.amplify.aws/react/start).

```bash
npm create amplify@latest
```

## Package Description

`@aws-amplify/data-schema` contains:

1. Schema Builder API implementation (`a.schema()`, `a.model()`, `a.string()`, etc.)
1. Type mapping that emits client-side types from the schema definition
1. `generateClient()` factory for generating a strongly-typed client from the schema definition
