body-parser-graphql [](https://www.npmjs.com/package/body-parser-graphql)\n[](https://github.com/semantic-release/semantic-release)[](https://circleci.com/gh/supergraphql/body-parser-graphql)[](https://codeclimate.com/github/supergraphql/body-parser-graphql)[](https://coveralls.io/github/supergraphql/body-parser-graphql)[](https://renovateapp.com/) \nExpress body-parser that supports the `application/graphql` MIME type.\n\n## How does it work?\n`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`.\n\nReceived request:\n```graphql\n{\n posts {\n id\n title\n }\n}\n```\n`request.body` value after the middleware:\n```js\n{\n query: {\n posts {\n id\n title\n }\n }\n}\n```\n\nIf an `application/json` request is received, it applies the JSON body-parser.\n\n## Installation\n\nInstall `body-parser-graphql` using your favorite package manager:\n```shell\n$ yarn add body-parser-graphql\n$ npm install body-parser-graphql\n```\n\n## Usage\n\nThe `body-parser-graphql` can be used as a drop-in replacement for the normal `json` body-parser.\n\n```diff\nimport * as express from 'express'\n- import * as bodyParser from 'body-parser'\n+ import * as bodyParser from 'body-parser-graphql'\n\nconst app = express()\n\n- app.use(bodyParser.json())\n+ app.use(bodyParser.graphql())\n\n// Your express routes\n\napp.listen(/* your configuration */)\n```\n\nAlternatively, you can also import the body-parser directly:\n\n```typescript\nimport { bodyParserGraphQL } from 'body-parser-graphql'\n\napp.use(bodyParserGraphQL())\n```\n\n\n
