Express body-parser that supports the `application/graphql` MIME type.

## How does it work?
`body-parser-graphql` checks the `Content-Type` header of the request. If the Content-Type is `application/graphql`, the request is transformed into a 'normal' `application/json` GraphQL request, and the `Content-Type` header is set to `application/json`.

Received request:
```graphql
{
posts {
id
title
}
}
```
`request.body` value after the middleware:
```js
{
query: {
posts {
id
title
}
}
}
```

If an `application/json` request is received, it applies the JSON body-parser.

## Installation

Install `body-parser-graphql` using your favorite package manager:
```shell
$ yarn add body-parser-graphql
$ npm install body-parser-graphql
```

## Usage

The `body-parser-graphql` can be used as a drop-in replacement for the normal `json` body-parser.

```diff
import * as express from 'express'
- import * as bodyParser from 'body-parser'
+ import * as bodyParser from 'body-parser-graphql'

const app = express()

- app.use(bodyParser.json())
+ app.use(bodyParser.graphql())

// Your express routes

app.listen(/* your configuration */)
```

Alternatively, you can also import the body-parser directly:

```typescript
import { bodyParserGraphQL } from 'body-parser-graphql'

app.use(bodyParserGraphQL())
```
