## Sangria akka-http Example

An example [GraphQL](https://graphql.org) server written with [akka-http](https://github.com/akka/akka-http), [circe](https://github.com/circe/circe) and [sangria](https://github.com/sangria-graphql/sangria).

[![Deploy](https://www.herokucdn.com/deploy/button.png)](https://heroku.com/deploy)

After starting the server with

```bash

sbt run

# or, if you want to watch the source code changes

 

sbt ~reStart

``` 

you can run queries interactively using [graphql-playground](https://github.com/prisma/graphql-playground) by opening [http://localhost:8080](http://localhost:8080) in a browser or query the `/graphql` endpoint directly. The HTTP endpoint follows [GraphQL best practices for handling the HTTP requests](http://graphql.org/learn/serving-over-http/#http-methods-headers-and-body).

Here are some examples of the queries you can make:

```bash

$ curl -X POST localhost:8080/graphql \

  -H "Content-Type:application/json" \

  -d '{"query": "{hero {name, friends {name}}}"}'

```

this gives back the hero of StarWars Saga together with the list of his friends, which is of course R2-D2:

```json

{

  "data": {

    "hero": {

      "name": "R2-D2",

      "friends": [

        {

          "name": "Luke Skywalker"

        },

        {

          "name": "Han Solo"

        },

        {

          "name": "Leia Organa"

        }

      ]

    }

  }

}

```

Here is another example, which uses variables:

```bash

$ curl -X POST localhost:8080/graphql \

  -H "Content-Type:application/json" \

  -d '{"query": "query Test($humanId: String!){human(id: $humanId) {name, homePlanet, friends {name}}}", "variables": {"humanId": "1000"}}'

```

The result should be something like this:

```json

{

  "data": {

    "human": {

      "name": "Luke Skywalker",

      "homePlanet": "Tatooine",

      "friends": [

        {

          "name": "Han Solo"

        },

        {

          "name": "Leia Organa"

        },

        {

          "name": "C-3PO"

        },

        {

          "name": "R2-D2"

        }

      ]

    }

  }

}

```
