```graphql
query {
  human(id: 1002) {
    name
    appearsIn
    starships {
      name
    }
  }
}

### Basic Setup with ASP.NET Core and EF Core

Source: https://github.com/graphql/graphql.github.io/blob/source/src/code/language-support/c-net/server/entity-graphql.md

This snippet demonstrates how to configure Entity GraphQL in an ASP.NET Core application using Entity Framework Core to automatically build a GraphQL schema from an existing data model.

```APIDOC
## Configure Entity GraphQL with ASP.NET Core and EF Core

### Description
This example shows the basic setup for exposing an existing data model as a GraphQL API using Entity GraphQL with ASP.NET Core and Entity Framework Core. It includes configuring services and endpoints.

### Method
N/A (Configuration)

### Endpoint
N/A (Configuration)

### Parameters
N/A

### Request Example
N/A

### Response
N/A

### Code Example (C#)
```csharp
// expose an existing data model with ASP.NET & EF Core
public class Startup {
  public void ConfigureServices(IServiceCollection services)
  {
      services.AddDbContext<DemoContext>();
      // Auto build a schema from DemoContext. Alternatively you can build one from scratch
      services.AddGraphQLSchema<DemoContext>(options =>
      {
          // modify the schema (add/remove fields or types), add other services
      });
  }

  public void Configure(IApplicationBuilder app, DemoContext db)
  {
      app.UseRouting();
      app.UseEndpoints(endpoints =>
      {
          // defaults to /graphql endpoint
          endpoints.MapGraphQL<DemoContext>();
      });
  }
}
```
```

### Install GraphQLBox Dependencies

Source: https://github.com/graphql/graphql.github.io/blob/source/src/code/language-support/javascript/client/graphql-box.md

Installs the core GraphQLBox packages along with necessary cache management and request parsing modules via npm.

```bash
npm install @graphql-box/core @graphql-box/client @graphql-box/request-parser @graphql-box/cache-manager @graphql-box/debug-manager @graphql-box/fetch-manager @graphql-box/helpers @cachemap/core @cachemap/reaper @cachemap/indexed-db @cachemap/constants @cachemap/types
```

### GET /graphql

Source: https://github.com/graphql/graphql.github.io/blob/source/src/pages/learn/serving-over-http.mdx

Executes a GraphQL query operation using the HTTP GET method. This is suitable for caching but limited by URL length constraints.

```APIDOC
## GET /graphql

### Description
Executes a GraphQL query operation. Use this for queries only; mutations must use POST.

### Method
GET

### Endpoint
/graphql

### Parameters
#### Query Parameters
- **query** (string) - Required - The GraphQL query document string.
- **variables** (string) - Optional - A JSON-encoded string of query variables.
- **operationName** (string) - Optional - The name of the operation to execute if multiple are provided.

### Request Example
GET /graphql?query={me{name}}&variables={"id":1}

### Response
#### Success Response (200)
- **data** (object) - The result of the GraphQL execution.
- **errors** (array) - Optional - List of errors if any occurred.
- **extensions** (object) - Optional - Additional metadata.

#### Response Example
{
  "data": {
    "me": {
      "name": "John Doe"
    }
  }
}
```

### Tartiflette Hello World Example

Source: https://github.com/graphql/graphql.github.io/blob/source/src/code/language-support/python/server/tartiflette.md

A Python script demonstrating a basic GraphQL API with Tartiflette. It defines a 'hello' query and executes it asynchronously. Requires the tartiflette library.

```python
import asyncio
from tartiflette import Engine, Resolver
@Resolver("Query.hello")
async def resolver_hello(parent, args, ctx, info):
    return "hello " + args["name"]
async def run():
    tftt_engine = Engine("""
type Query {
    hello(name: String): String
}
""")
    result = await tftt_engine.execute(
        query='query { hello(name: "Chuck") }'
    )
    print(result)
    # {'data': {'hello': 'hello Chuck'}}
if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(run())
```

### Execute Hello World GraphQL Query with graphql-clj

Source: https://github.com/graphql/graphql.github.io/blob/source/src/code/language-support/clojure/server/graphql-clj.md

This snippet demonstrates how to define a GraphQL schema and execute a simple 'Hello world!' query using the graphql-clj library. It involves setting up the schema, defining a resolver function, and using the executor to process the query. Dependencies include the graphql-clj library itself.

```clojure
(def schema "type QueryRoot {
    hello: String
  }")

(defn resolver-fn [type-name field-name]
  (get-in {"QueryRoot" {"hello" (fn [context parent & rest]
                              "Hello world!")}})
          [type-name field-name]))

(require '[graphql-clj.executor :as executor])

(executor/execute nil schema resolver-fn "{ hello }")
```
