This is the Koa integration of GraphQL Server. GraphQL Server is a community-maintained open-source GraphQL server that works with all Node.js HTTP server frameworks: Express, Connect, Hapi, Koa and Restify. [Read the docs](http://dev.apollodata.com/tools/apollo-server/index.html).

## Principles

GraphQL Server is built with the following principles in mind:

* **By the community, for the community**: GraphQL Server's development is driven by the needs of developers
* **Simplicity**: by keeping things simple, GraphQL Server is easier to use, easier to contribute to, and more secure
* **Performance**: GraphQL Server is well-tested and production-ready - no modifications needed


Anyone is welcome to contribute to GraphQL Server, just read [CONTRIBUTING.md](./CONTRIBUTING.md), take a look at the [roadmap](./ROADMAP.md) and make your first PR!

## Usage

```js
import koa from 'koa'; // koa@2
import koaRouter from 'koa-router'; // koa-router@next
import koaBody from 'koa-bodyparser'; // koa-bodyparser@next
import { graphqlKoa } from 'graphql-server-koa';

const app = new koa();
const router = new koaRouter();
const PORT = 3000;

// koaBody is needed just for POST.
app.use(koaBody());

router.post('/graphql', graphqlKoa({ schema: myGraphQLSchema }));
router.get('/graphql', graphqlKoa({ schema: myGraphQLSchema }));

app.use(router.routes());
app.use(router.allowedMethods());
app.listen(PORT);
```
