# CDS protocol adapter for GraphQL

## About this project

A GraphQL protocol adapter for [SAP Cloud Application Programming Model](https://cap.cloud.sap) Node.js.

This adapter generically generates a GraphQL schema for the models of an application and serves an endpoint that allows you to query your services using the GraphQL query language.

_**WARNING:** This package is in an early general availability state. This means that it is generally available, with stable APIs unless otherwise indicated, and you can use it for production. However, please note the [current limitations](#limitations) listed below._

## Requirements and Setup

1. Simply add the GraphQL adapter to your project using `npm`:

   ```js

   npm add @cap-js/graphql

   ```

> This command will set up the GraphQL plug-in with the `@sap/cds` runtime. It enables the new [middlewares architecture](https://cap.cloud.sap/docs/node.js/middlewares) in Node.js and registers a GraphQL endpoint at `/graphql` serving all CRUD requests for the application services found in your model.

  

2. Annotate the services you want to serve, e.g. using `@graphql` or `@protocol: 'graphql'`.

3. Run your server as usual, e.g. using `cds watch`.

> The runtime will serve all annotated services via GraphQL at the default configured endpoint.

## Limitations

- **Actions** and functions are not yet supported.

- **CDS annotations** like `@readonly` aren’t considered during schema generation.

- **Cursor-based Pagination** – we currently support offset-based pagination, and will add cursor-based pagination going forward. While we intend to support both variants then, it is not guaranteed that we can do so without breaking changes to current behaviour.

- **Extensions** are not yet considered.
